Description

The invention relates to devices, devices and methods for distribution, Billing and payment of digital media content.

The Internet is ideal as a global digital network as a technical platform for the distribution of digital data from content providers their customers. Media content such as texts, audio content such as music or speech, Images and moving video content are now almost entirely digital Shape produced or can be digitized with little effort. By advanced compression techniques such as MP3 (for audio Area) or MPEG (for the video area) can also contain data-intensive content over today's still relatively narrow-band on the consumer side Internet infrastructure can be transported. Also for use by the Customer specific software belongs in the context of the present Invention for the aforementioned digital content.

A provider of such multimedia content typically operates one a broadband dedicated line constantly connected to the internet and particularly powerful computer, a so-called "server". The customer the content provider must each have access to one using the internet have connected or connectable computers, for example to one so-called "personal computer" (PC), and using suitable Internet Service protocols such as - in the simplest case - the "hypertext Transport Protocol "(HTTP) the content representing data from the server download the local computer ("client"). The digital content often stored in the form of a file on the local computer before they can be used there. Alternatively, so-called "streaming" - Protocols are available where the data representing the content during the download from the server computer to the client computer can be immediately converted into perceptible sensory impressions without the client computer generates a file corresponding to the digital content and is filed.

It is no longer just stationary devices according to Art of a PC into consideration, which is connected to the Internet connected or connectable. Mobile devices are available that easily can be taken along. Examples of this are handy players ("Player") for example for MP3 audio files or for digital reading materials ("e- Books "). Recently, devices for converting digital content into perceptible sensations known via a wireless Radio frequency connection to the Internet, for example Mobile phone networks such as GSM or UMTS.

With regard to those technical devices and processes that are used be a digital content in a sensual for the consumer implement perceptible form; usually become different Differentiated media types. For texts and images including video Sequences are addressed to the eye and one speaks of "Display devices" or "display method". With the sense of hearing responsive audio media is referred to as "playback devices" or "rendering process". It is possible that digital media also address other senses, in particular the sense of touch and the sense of smell. The object of this invention is in its most general form in one Relationship to the implementation of all of these different media types into one suitable form for each sensory perception. The following text The general inventive aspects discussed apply regardless of certain linguistic expressions such as "display", "playback", "playback" etc., basically for all forms of media consumption, as long as they are not explicitly to certain media types, such as page oriented Texts are limited. The use of software is also included here subsumed, because even when running software such as one The consumer interacts with a computer game or word processing software on the level of sensory impressions. Regardless, it appears unavoidable that there are concrete, illustrative examples restrict to certain media types.

There are unresolved problems with billing and Payment concepts for this type of modern distribution of digital content.

Experience has shown that the first and fundamental question is whether the customer is at all willing for the consumption of digital content on the Internet through the pure Internet connection costs, fees to the respective Pay content providers. The answer to this question depends essentially depends on the required technical infrastructure.

• 1. Zum einen ist - zumindest für die Vereinigten Staaten - inzwischen durch Gerichtsprozesse deutlich geworden, dass zumindest das ursprüngliche Geschäftsmodell wohl nicht durch die Schrankenbestimmungen des U.S.- Copyright-Rechtes gedeckt sein dürfte.
• 2. Zum anderen basiert der Geldfluß vom Konsumenten zum Anbieter nach der Theorie dieses Geschäftsmodells immer noch auf dem Verkauf materieller Güter, denn nur durch den Kauf einer entsprechenden Audio-CD sollte sich der Konsument den Zugang zum Server verschaffen können.
  Dies muß in Zeiten einer digitalen Internet-Ökonomie als Nachteil gewertet werden.
• 3. Dadurch, dass die vom Server heruntergeladenen MP3-Audiodateien die ursprünglich auf der Audio-CD vermarkteten Werke in überaus guter Qualität repräsentieren und darüber hinaus über das Internet ohne großen Aufwand und ohne weiteren Qualitätsverlust weiterverbreitet werden können, entsteht ein Anreiz für die Kunden des Unternehmens, die heruntergeladenen MP3-Audiodateien ihrerseits nicht etwa nur engen Freunden oder Verwandten, sondern darüber hinaus einer breiten Öffentlichkeit unentgeltlich zur Verfügung zu stellen. Dadurch entgehen den Inhalteanbietern Einnahmen, da die Verbreitung der MP3-Audiodateien in einem weitaus größeren Umfeld stattfindet als der entgeltliche Verkauf der Audio-CDs.
• 4. Schließlich ist der temporäre Besitz einer passenden Audio-CD nicht mit einer legitimen Eigentümerstellung an diesem Datenträger gleichzusetzen, d. h. es ist nicht auszuschließen, dass Audio-CDs vom Eigentümer kurzzeitig an Dritte ausschließlich zum Zweck der Zugangsverschaffung auf dem Server ausgeliehen werden.

For example, a United States-based company (MP3.COM) operates a business that includes an offer to all Internet users, originally content distributed only as an audio CD ("compact disk") in the form of audio files in MP3 format free of charge to be able to download. The original concept originally contained a control component in such a way that the downloading of the MP3 audio file belonging to a specific audio CD from a central server operated by the company is only enabled for a single customer if this customer previously had a characteristic data sample of a corresponding audio -Transfer CD to the server, whereby the proof should be provided that the customer in question already has a purchase of this CD and the provision of a corresponding MP3 audio file is covered by copyright restrictions. This approach cannot be considered forward-looking for several reasons:

• 1. On the one hand - at least for the United States - legal proceedings have now made it clear that at least the original business model is unlikely to be covered by the limitation provisions of US copyright law.
• 2. On the other hand, according to the theory of this business model, the flow of money from the consumer to the supplier is still based on the sale of material goods, because the consumer should only be able to gain access to the server by purchasing an appropriate audio CD.
  In times of a digital internet economy, this must be seen as a disadvantage.
• 3. The fact that the MP3 audio files downloaded from the server represent the works originally marketed on the audio CD in extremely good quality and can also be redistributed via the Internet without great effort and without further loss of quality, creates an incentive for the customers of the Company to make the downloaded MP3 audio files available not only to close friends or relatives, but also to a broad public free of charge. This means that content providers lose revenue because the distribution of MP3 audio files takes place in a much larger environment than the sale of audio CDs for a fee.
• 4. Finally, the temporary possession of a suitable audio CD cannot be equated with a legitimate ownership position on this data carrier, ie it cannot be ruled out that audio CDs can be loaned to the third party by the owner for the sole purpose of providing access to the server.

Possibly also in view of the deficits of the above Billing and payment concept from MP3.COM has another in the United States-based company, Napster Inc., another Business model developed, the users of which can enjoy free of charge especially digital content present as MP3 audio files. With this concept ("peer-to-peer file sharing") there is no central one Server computers for storing digital content more; the MP3 audio files and other content is only available on the local client computers under the Control of the customers of this company saved. The central Napster Server computer only takes on a mediation function, i. H. he takes from Napster customers receive a request for specific digital content and then delivers the Internet address of such client computers on which a corresponding file is available for download. retrievable is therefore only what at least one Napster Customer to download on a computer under his control ready for call. The original business concept assumes that the non-commercial exchange of copyrighted works under Private is covered by copyright restrictions, whereby it is assumed that the commercial brokerage through Napster non-commercial-private nature of the distribution of digital content is not impaired. In this case too it seems to have become clear at the moment that the business model is at least in line with the U.S. Copyright law is not compliant.

In the known peer-to-peer concepts, there is a flow of money from the consumer Conceptually not intended for content providers. The owners of the Exploitation rights for digital content therefore feel a significant lack available technical concepts to also under the conditions of Internet economists bill and earn a reasonable fee can.

Here, technical approaches, peer-to-peer transactions appear on the Internet for example at the level of the infrastructure of Internet access providers To fundamentally want to prevent forced filtering of Internet data streams, to be problematic. Firstly, from political and legal aspects out that there is a need for widespread enforcement of these concepts is possible. Secondly, new technical ones are constantly being added Concepts designed to facilitate file sharing through peer-to-peer transactions last but not least to harden against legal-administrative interventions. An example for this is the peer-to-peer file transfer protocol "Gnutella", which in contrast to the Napster concept without a central mediation server. Against the identifiability of the client participants of such a protocol and the related coherent possibility, against the legal-administrative way the use of these techniques have become cryptographic Anonymization techniques are available, such as those in the so-called "Freenet" protocol have been incorporated.

A basic technical requirement for the possibility of a sustainable Billing of a usage fee for the use of digital content Consumers are adequately protected against unauthorized reproduction. If this problem is not solved, it does not appear to be economically viable Billing possible.

• - die Distribution von digitale Inhalte verkörpernden Dateien sowohl über das Internet als auch mittels körperlicher Datenträger wie beispielsweise CDs ausschließlich in verschlüsselter Form erfolgt, und/oder
• - bei denen digitale Inhalte verkörpernde Dateien mit steganographisch verdeckten Informationen, sogenannten "Wasserzeichen" oder "Watermarks", versehen sind, die Auskunft über den urheberrechtlichen Status der darin abgebildeten Werke wiedergeben und die durch den Konsumenten nicht wieder durch illegitime technische Manipulationen aus den die digitalen Inhalte repräsentierenden Dateien entfernt werden können.

For this purpose, cryptographic concepts are available in which

• - The distribution of digital content-embodying files takes place exclusively in encrypted form both over the Internet and by means of physical data carriers such as CDs, and / or
• - in which digital content-embodying files are provided with steganographically concealed information, so-called "watermarks" or "watermarks", which provide information about the copyright status of the works depicted therein and which are not reproduced by the consumer through illegitimate technical manipulations from the digital ones Files representing content can be removed.

The cryptographic keys required to decrypt the files As a consequence of this approach, any unauthorized access by third parties, especially effectively and reliably withdrawn from that of consumers become. This can be realized in a particularly advantageous form by Bring content providers to special devices or from others let interested companies bring to the market on their functional Reliability of content providers relies on them and in particular cryptographic keys preferably, for example, in special ones sealed assemblies are included, with appropriate technical Measures are taken to ensure that the data stored therein cryptographic keys are instantly deleted as soon as one Manipulation attempt is detected.

Embedding watermarks in digital content enables you to do so no sustainable billing practice for media use the consumers. The content provider also has control over this the equipment required by means of which consumers can use the manage digital content. The devices are based on their functionality the content provider (s) rely, designed to Filter out the steganographically embedded copyright information and in suitably evaluate to unauthorized use, in particular to prevent unauthorized duplication.

An example of such a technical infrastructure is from the SDMI project (Secure Digital Music Initiative) known.

In general, devices and methods that serve the copyright monopoly of the author or his legal successor technically enforce digital content as "Digital Rights Management System "(DRMS).

Technical concepts for DRMS are for example from US-A-6,112,181 as well known from US-A-6,138,119.

But also such a closed technical infrastructure with a DRMS, the consumer any use not authorized by the content provider digital content effectively and permanently blocked does not solve the problem distribution, billing and payment of digital content as flexible as possible both on the Internet and by means of physical data carriers such as for example CDs.

Nevertheless, the coupling with a cryptographically prevents abuse "hardened" DRMS in a method of spreading according to the invention, Billing and payment of digital media content as well as at one corresponding device is only a preferred form of implementation; compellingly Such a cryptographically hardened DRMS is not required.

DRMS are known, with which digital content by means of suitable technical concepts, pricing information can be added. For example, are based on XML ("Extensible Markup Language") Markup language XrML ("Extensible rights Markup Language"), whose Specification can be obtained from http://www.xrml.org/, precautions included to provide pricing information in a data processing system map a suitable shape. However, such approaches create problems in the area of technical settlement of billing and payment still not solved satisfactorily.

As things stand, such closed systems include one DRMS can only be enforced on the market if it is also for the consumer offer noticeable advantages, because the presence of the DRMS is determined by the Consumers tend to be viewed as a hindrance at first. But it is also not in such a way that consumers are not ready for use pay digital content to the content provider; it rather comes to the fact that the methods of billing and payment the To meet customer requirements. In this regard, the current one State of the art significant deficits.

One of the problems of previous technical systems for distribution, billing and paying for digital content is that it is too inflexible Set up concepts for purchase or subscription pricing.

For example, systems are known in which, for example, by credit card payment A full purchase price must be paid before any digital content representing file can be downloaded from a server computer. This leads in particular to the fact that a prior, free viewing of the digital content by the consumer on suitability, favor, etc., etc. is no longer possible. This creates a high inhibition threshold for the acquisition of digital content created by purchase, because if you don't like one Reverse processing of the purchase usually fails because of the consumer - unlike for example when buying a physical book or a CD - the factual power of disposal over him as a copy transferred file is difficult to reliably withdraw.

On the other hand, systems are known which have a usage-dependent distribution, Billing and payment of digital content according to the type of "video on demand" enable. However, such systems have the disadvantage that the Fine-grained accounting for the existence of a data connection of the Terminal (client) is coupled to a server of the content provider. Even though the data transmission costs by using modern Telecommunications technology is steadily falling, it is currently an unrealistic one Assumption that consumers always have one when using digital content uninterrupted and secure access to telecommunications networks will be available at a low cost.

An important social aspect when using media is the option of Consumers to be able to act anonymously when purchasing media, for example, by purchasing physical media for cash on one Kiosk. Known digital distribution, billing and payment concepts under Use of data traffic networks such as the Internet in particular are based on an identifiability of the individual consumers. There is a need for an improved technical infrastructure for distribution, billing and Payment for digital content in which the consumer also acts anonymously can.

As is well known, the market for digital content prevails as well as the market for technical devices with which digital content is sensual to the consumer a competition that is very different produces technical embodiments of this technical infrastructure. It is a major disadvantage for the customer, however, if this diversity is also reflected in a variety of accounting and payment systems. In in practice, this diversity means that consumers are expected to to maintain numerous individual contracts with providers of payment systems, such as for example credit card companies, companies for mobile-based Payment systems and others. Due to these disadvantages, the acceptance of technical infrastructures for controlled distribution, billing and Payment of digital content is severely impaired.

The object of the invention is therefore to provide an apparatus and a method for Specify the distribution, billing and payment of digital content where the above disadvantages are reduced or overcome and in which in particular a finer-level billing without permanent data connection for example with a billing server.

The object is achieved by the features of the independent Claims. Advantageous embodiments of the invention are in each subordinate claims referring to them.

• - Zum einen führt dieser Ansatz dazu, dass der volle Kaufpreis berechnet wird, auch wenn der Konsument nur einen Teil der auf dem Datenträger gespeicherten Inhalte nutzt.
• - Außerdem erfordert die Verbreitung von Medieninhalten durch Vertrieb körperlicher Vervielfältigungsstücke eine aufwendige und kostenträchtige Logistik bei Herstellung, Lagerung und Verkauf der Datenträger.
• - Zum anderen ermöglicht aber die Körperlichkeit der Datenträger eine vergleichsweise einfach zu handhabende Abrechnung der vom Konsumenten zu entrichtenden Entgelte, vorausgesetzt, die unkontrollierte Duplizierung der Datenträger ist für den Konsumenten hinreichend unattraktiv, beispielsweise hinsichtlich des zum Kopieren erforderlichen Aufwandes oder hinsichtlich unvermeidlicher Qualitätsverluste, wie sie etwa bei Analogkopien von Inhalten auf Audio- oder Videokassetten zwangsläufig auftreten.

The solution according to the invention enables an improved technical infrastructure for the distribution (distribution), billing and payment of digital content, by means of which a partial or total departure from the rigid binding of media use to the purchase of material data carriers such as CDs, DVDs or video cassettes can be implemented , According to the principles of conventional media use, the consumer acquires a single copy of a physical data medium with content recorded on it through a purchase act, which he can dispose of at his own discretion:

• - On the one hand, this approach leads to the full purchase price being calculated, even if the consumer only uses part of the content stored on the data carrier.
• - In addition, the distribution of media content through the distribution of physical copies requires complex and costly logistics in the manufacture, storage and sale of the data carriers.
• - On the other hand, the physicality of the data carrier enables a comparatively easy to handle billing of the fees to be paid by the consumer, provided that the uncontrolled duplication of the data carrier is sufficiently unattractive for the consumer, for example in terms of the effort required for copying or inevitable loss of quality such as that such as inevitably occur with analog copies of content on audio or video cassettes.

In the transition to the non-physical distribution of digital content via Data networks are automatically eliminated due to the high physicality of the Disk-related transaction costs. At the same time, however, none of them Differentiation between the legitimate through a purchase act Acquired "original" of a file representing digital content and its copies made almost effortlessly and free of charge. With a digital distribution of files via data transmission networks such as the Internet in particular Distinguishing between "original" and "copy" no longer makes any sense.

The solution according to the invention is therefore based on the approach that in one digital economy the purchase of copies of digital content representing file with the following and logically based on it Right of disposal of the consumer purchasing the copy must be replaced or at least supplemented by the concept of (in the Granting access and usage rights ("fee Rights ") to the consumer, but this no longer means ownership to exercise typical material control over a data carrier in the Location is.

• - wird einerseits eine Lösung des Problems der beliebigen Kopierbarkeit von digitale Inhalte repräsentierenden Dateien ermöglicht, da durch eine in geeigneter Weise ausgestaltete technische Infrastruktur der Besitz von ("Original"-)Dateien durch den Konsumenten nicht mehr für den Nutzungsvorgang ausschlaggebend ist; während nämlich im Zusammenhang der erfindungsgemäßen Lösung die Dateien als solche im Prinzip ohne Beeinträchtigung der Interessen der Rechteinhaber durch den Konsumenten beliebig kopiert und verbreitet werden können, muß nur die für die Nutzung der in den Dateien enthaltenen Inhalte erforderlichen kritischen Zugangsrechtsinformation wiederum mit technischen Mitteln gemäß der erfindungsgemäßen Lösung streng unter Kontrolle gehalten werden;
• - wird andererseits potentiell die Gefahr aus der Abhängigkeit des Konsumenten von der fortwährenden Einräumung von Zugangs- und Nutzungsrechten durch den Inhalteanbietern größer, denn im Gegensatz zum Kauf- und Besitzmodell herkömmlicher Prägung basiert das Zugangs- und Nutzungsmodell auf der Annahme, dass dem Konsumenten fortwährend ein Inhalteanbieter als Gegenüber zur Verfügung steht, der gewillt, bereit und in der Lage ist, die aufgrund von Zugangs- und Nutzungsrechten ihm zustehende Leitung auch tatsächlich zu erbringen. Stellt der Inhalteanbieter - aus welchen Gründen auch immer - seinen Geschäftsbetrieb ein oder verzichtet er beispielsweise aus wirtschaftlichen Überlegungen oder auf äußeren Druck auf die Fortführung der Vermarktung eines bestimmten Inhaltes, so ist der Konsument nicht mehr wie beim Kauf- und Besitzmodell in der Lage, auf sein erworbenes, in Besitz genommenes und archiviertes Vervielfältigungsstück für eine fortgesetzte Konsumnutzung zurückzugreifen.

Through this paradigm shift away from purchase and possession and towards temporary granting of access and usage rights

• - On the one hand, a solution to the problem of the arbitrary copiability of files representing digital content is made possible, since through a suitably designed technical infrastructure, the possession of ("original") files by the consumer is no longer decisive for the usage process; while in the context of the solution according to the invention the files as such can in principle be copied and distributed as desired without impairing the interests of the rights holders by the consumer, only the critical access right information required for the use of the contents contained in the files must again be obtained using technical means in accordance with the solution according to the invention are kept strictly under control;
• - On the other hand, the risk from the dependency of the consumer on the constant granting of access and use rights by the content provider is potentially greater, because in contrast to the purchase and ownership model of conventional character, the access and use model is based on the assumption that the consumer is constantly Content provider is available as a counterpart who is willing, willing and able to actually perform the management due to access and usage rights. If the content provider - for whatever reason - ceases to operate its business or, for economic reasons or for external pressure, for example, refrains from continuing to market a certain content, the consumer is no longer able to, as with the purchase and ownership model to use his acquired, owned and archived copy for continued consumption.

The solution according to the invention therefore provides, in particular, a technical infrastructure with which an access and use concept as a replacement or supplement to the purchase and ownership model is technically possible:
The aspect of the integration of a card module in a solution according to the invention, which is explained in more detail below, also makes it possible to incorporate "use" and "possession" in a synthesis, since the right of use can be linked to a physical object which is difficult to duplicate and which also the consumer embodies the rights of use transferred to him.

• - Zum einen ist ein gleichmäßiger Qualitätsstandard gewährleistet, d. h. im Gegensatz zu nicht-kommerziellen unentgeltlichen Tauschbörsen muß der Konsument nicht mit technisch mangelhaft aufbereiteten Dateien rechnen, und
• - durch das unten näher erläuterte Konzept der Statusrechte und dessen technischer Implementierung ist es auf der kaufmännischen Ebene möglich, Angebote zu gestalten, bei denen der Konsument über die reine, einen digitalen Inhalt repräsentierende Datei hinaus einen attraktiven Mehrwert erwerben kann.

The advantages of the solution according to the invention make it possible to make concepts for the use of digital content by the consumer, which are subject to payment, more attractive in relation to free exchanges, since the consumer receives more than just a file embodying digital content:

• - On the one hand, a uniform quality standard is guaranteed, ie in contrast to non-commercial, free exchange exchanges, the consumer does not have to reckon with technically inadequate files, and
• - The concept of status rights and its technical implementation, which is explained in more detail below, makes it possible on the commercial level to design offers in which the consumer can acquire attractive added value beyond the pure file representing digital content.

Technical portal solution

• - Gezielte Individuelle Übertragung bestimmter Inhalte "on demand" von der Portal-Datenverarbeitungseinrichtung an eine bestimmte, bei einem Konsumenten betriebene Vorrichtung, und
• - Ungezielte Übertragung bestimmter Inhalte durch "Broadcast"-Techniken von der Portal-Datenverarbeitungseinrichtung an eine unbestimmte Vielzahl von bei einer Menge von Konsumenten betriebenen Vorrichtungen.

A first aspect in connection with the invention is that the distribution (distribution), billing and payment of digital media content for a large number of content providers and for a large number of consumers can be handled via a technical portal data processing device. In particular, files representing digital content can be loaded via digital wide area networks (WAN) on the one hand by content providers onto the portal data processing device and on the other hand downloaded by the consumer from this portal data processing device. In particular, two forms of expression are provided:

• - Targeted individual transmission of certain contents "on demand" from the portal data processing device to a specific device operated by a consumer, and
• - Untargeted transmission of certain content by "broadcast" techniques from the portal data processing device to an indefinite number of devices operated by a large number of consumers.

The portal data processing device can also access and Manage usage rights and billing data from consumers operate operated devices and based on this Billing data bills both that of each consumer Paying usage fees as well as invoices to the individual Make royalties payable to content providers. Finally, the Portal data processing device also the corresponding payment processes transact.

• - Zum einen bleibt dem Konsumenten der Abschluß einer Vielzahl von Einzelverträgen mit Rechteinhabern erspart; erforderlich ist lediglich ein einziger Globalvertrag mit dem Portalbetreiber.
• - Zum anderen kann das Portal-Datenverarbeitungssystem zu einem Inhaltearchiv für alle jemals vermarkteten Dateien mit digitalen Inhalten ausgebaut werden, wodurch der Portalbetreiber gegenüber dem Konsumenten in die Lage versetzt wird, eine Art "Garantenstellung" bezüglich der weiteren Verfügbarkeit der zum Zugangs- und Nutzungsrecht gehörenden Leistung einzunehmen. Auch wenn der Rechteinhaber einen bestimmten Inhalt aufgegeben hat und die entsprechenden Dateien nicht weiter pflegen und archivieren will (sogenannte "Abandonware"), kann der Konsument über die Portal-Datenverarbeitungsvorrichtung eine seinen Zugangs- und Nutzungsrechten gemäße Gegenleistung erhalten.

It is particularly advantageous if the portal data processing device is operated in a mode in which the contents of numerous rights holders are marketed together:

• - Firstly, the consumer is spared the conclusion of a large number of individual contracts with rights holders; All that is required is a single global contract with the portal operator.
• - On the other hand, the portal data processing system can be expanded into a content archive for all files with digital content ever marketed, which enables the portal operator to provide the consumer with a kind of "guarantee" regarding the further availability of those belonging to the right of access and use Performance. Even if the rights holder has given up a certain content and does not want to maintain and archive the corresponding files (so-called "abandonware"), the consumer can receive a consideration in accordance with his access and usage rights via the portal data processing device.

The portal data processing device can also be designed such that they are operated as part of "peer-to-peer" exchanges can. The digital content embodying files are based on, for example Client computers operated by the consumer are available for access. The Management of access and usage rights as well as those related to the functions related to billing and payment then remain typically at the portal data processing facility.

Offline mode

A second aspect in connection with the invention is that the Billing and / or payment of fees for use digital content is not necessarily synchronized with the usage process itself must be designed. That is, depending on the lending policy of Content providers or billing companies can give consumers the opportunity be granted a certain amount of use of digital content make a suitable device according to the invention without an uninterrupted traffic connection during this time any billing center, especially for portal Data processing device must exist. To do this during a Time interval between two billing times all required data collected locally about the usage behavior of the consumer in order to billing the contractually due usage fee next billing time to be able to. This recorded data is preferred by suitable ones Techniques against unauthorized manipulation, in particular by the Protected consumers. It can be provided that the consumer receives a Deposit amount must be deposited in order to credit the credit risk by later Intercept usage of digital content. One is preferred Design where the risk for the content provider or service provider is limited by the fact that further use of digital content is blocked, if the accumulated remuneration exceeds a certain threshold. Only after billing and payment has been made will further use become digital Content released again.

card module

A third aspect in connection with the invention is that especially for storing identity, billing and Payment information preferably an interchangeable module-like element, For example, a chip card or a flash memory module can be used can.

This module does not necessarily have to be a card; It is also possible to use other designs, such as those for the Attaching, in particular sewing or gluing, into clothing are suitable.

For the sake of simplicity, the term "card module" is used in the following; however, other designs are expressly considered to be included.

The card module has an interface by means of which it can share data with others Can replace devices, especially with a device that is suitable and is intended to make digital content perceptible to the consumer make, which is hereinafter referred to as "user device". This Data transmission can, for example, be wired via electrical Connectors, contact fields or coupling lines are made. Likewise, the Wireless data transmission via radio link, for example after Bluetooth standard, or by magnetic induction or optically, for example with Infrared coupling according to the IrDA standard.

• - bei der Verbreitung (Distribution) digitaler Inhalte, beispielsweise durch Speicherung werkbezogener Adreßinformationen, d. h. Referenzinformationen über Netzwerkpfade, über die digitale Inhalte erreichbar sind, oder durch Speicherung der digitale Inhalte repräsentierenden Dateien auf dem Kartenmodul;
• - bei der Abrechnung durch Speicherung abrechnungsbezogener Daten auf dem Kartenmodul, und
• - bei der Bezahlung durch Speicherung von Daten auf dem Kartenmodul, die im Zusammenhang mit der Zahlungsmethode und dem Zahlungsweg stehen.

A card module can be used advantageously in connection with the solution according to the invention

• - in the distribution (distribution) of digital content, for example by storing work-related address information, ie reference information on network paths via which digital content can be reached, or by storing files representing digital content on the card module;
• - when billing by storing billing-related data on the card module, and
• - When paying by storing data on the card module that are related to the payment method and the payment method.

The use of a card module in particular also makes one Bundling of contracts makes it easier because the card module in connection with a A variety of individual devices can be used for the otherwise separate use and Remuneration contracts would have to be concluded.

DRMS

• - Bei Anwendung eines Kartenmoduls können die multimedialen Werke einerseits decoderspezifisch, nicht kartenspezifisch verschlüsselt werden, d. h., die Karte wird zur Berechtigung gegenüber dem Decoder verwendet, wohingegen die Daten der die zu nutzenden digitalen Inhalte repräsentierenden Dateien vom Nutzungsgerät mittels im Decoder abgelegter kryptographischer Entschlüsselungsschlüssel entschlüsselt und in eine sinnlich wahrnehmbare Form umgesetzt werden. Dabei authentifiziert sich das Kartenmodul bevorzugterweise mittels geeigneter kryptographischer Protokolle unter Verwendung der Datenübertragungsschnittstelle gegenüber dem Nutzungsgerät.
• - Bei Anwendung eines Kartenmoduls können die multimedialen Werke andererseits kartenspezifisch, nicht decoderspezifisch verschlüsselt werden, d. h., die Karte wird zur Speicherung der zur Entschlüsselung der digitalen Inhalte erforderlichen kryptographischen Entschlüsselungsschlüssel herangezogen, wobei diese Entschlüsselungsschlüssel über eine hinreichend sichere Datenübertragungskopplung zum Decoder übertragen werden können. Die Daten der die zu nutzenden digitalen Inhalte repräsentierenden Dateien können dann vom Nutzungsgerät mittels der von dem Kartenmodul übertragenen kryptographischen Entschlüsselungsschlüssel entschlüsselt und in eine sinnlich wahrnehmbare Form umgesetzt werden.

A fourth aspect in connection with the invention consists in that all files which embody digital content are preferably distributed in encrypted form. In this way, any unauthorized use of digital content can be effectively prevented in connection with a cryptographic DRMS. In connection with the use of a cryptographic DRMS, it is necessary to store the key or keys, the cryptographic keys required for the lawful decryption of the digital content, in a suitable technical manner so that the consumer can use the content distributed in encrypted form. There are two cases when using a card module:

• - When using a card module, the multimedia works can be encrypted on the one hand decoder-specific, not card-specific, i.e. the card is used to authorize the decoder, whereas the data from the files representing the digital content to be used is decrypted by the user device using cryptographic decryption keys stored in the decoder be implemented in a sensible form. The card module preferably authenticates itself to the user device by means of suitable cryptographic protocols using the data transmission interface.
• - On the other hand, when using a card module, the multimedia works can be encrypted card-specifically, not decoder-specifically, i.e. the card is used to store the cryptographic decryption keys required to decrypt the digital content, whereby these decryption keys can be transmitted to the decoder via a sufficiently secure data transmission link. The data of the files representing the digital content to be used can then be decrypted by the user device using the cryptographic decryption keys transmitted by the card module and converted into a form that can be perceived by the senses.

Flexible pricing models

• - einem werkspezifischen Werketarif, bei dem die Abrechnung unabhängig vom Gerät nach Maßgabe von Eigenschaften des Werkes erfolgt, und
• - einem gerätespezifischen Gerätetarif, bei dem die Abrechnung unabhängig vom Werk nach Maßgabe von Eigenschaften des Gerätes erfolgt, sowie
• - hybride Tarifstrukturen aus Werketarif und Gerätetarif, bei dem beispielsweise ein Werk mit einem höheren Entgelt abgerechnet werden kann, wenn es auf einem Gerät genutzt wird, welches eine höhere Darstellungsqualität (größerer Bildschirm, bessere Tonqualität oder dergleichen) ermöglicht.

A fifth aspect in connection with the invention is that the consumption of digital content is recorded in a finely graded manner and is billed fairly. This means in particular that a possibility is created whereby the consumer only pays the content provider a fee for the parts of the multimedia works that he actually used. If only part of a multimedia work is used, a tariff can be provided that also only bills part of the fee for the use of the entire work. A distinction is made between

• - a factory-specific factory tariff, where billing takes place independently of the device according to the characteristics of the factory, and
• - a device-specific device tariff, where billing takes place independently of the factory according to the properties of the device, and
• - Hybrid tariff structures consisting of works tariff and device tariff, in which, for example, a work can be billed at a higher fee if it is used on a device that enables a higher display quality (larger screen, better sound quality or the like).

• - die zeitbezogene Abrechnung, beispielsweise genutzte Hörzeit bei Audioinhalten;
• - die volumenbezogene Abrechnung, beispielsweise Anzahl der genutzten Seiten eines seitenorientierten Textinhaltes;
• - hybride Abrechnungsmodelle, beispielsweise eine durch zeitbezogene Tarifierungsanteile modifizierte volumenorientierte Abrechnung bei einem seitenorientierten Textinhalt.

Basic instruments for the work tariff are

• - Time-based billing, for example listening time used for audio content;
• - the volume-based billing, for example the number of pages used for a page-oriented text content;
• - Hybrid billing models, for example volume-based billing modified by time-based tariff components for page-oriented text content.

For example, that could be used for half the volume of one digital content, the usage fee is half the amount for the usage of the total content of the intended fee. At a digital content in the form of a text work (book) could for example be a Dimensioning based on the pages used in relation to the total number of Pages are made. But also other non-linear pricing models are possible. Furthermore, a differentiation is made possible as to whether the consumer is a multimedia work like a conventional purchase after a single payment would like to use a fee as often as desired or whether Limitation of usage processes with a significantly reduced fee in Comes into consideration. For example, the fee assessment for a text work also depend on how often the individual text pages of the consumer have been used.

Is the fee for the use of a page-oriented text work exclusively calculated per page display process, there is the serious disadvantage that a Intuitively searching "browsing" for the consumer is extremely cost-intensive is billed because this process may involve a large number of Page displays take place in a short time without the respective page content, as assumed in this pricing model, actually from Consumers could have been used. On the other hand, the fee for the Use of a page-oriented text work would be calculated purely time-dependent a slow reader versus a fast reader as a consumer unduly disadvantaged. An advantageous complex pricing model can in particular, provide a predetermined page fee per page advertisement, whereby a predetermined orientation time is set, before which a page is not assumed to be readable by the reader. This allows one non-discriminatory scrolling function. In addition, each page can have one predetermined reading time can be assigned, after the expiry of the Classification is assumed that the consumer has the offered Can fully accommodate page content. Is the period of time a particular one Page after the orientation time expires on the display is displayed, less than the predetermined reading time, is faked, for example, the reader only used the content to the extent that the Ratio of actual, beyond the orientation time Display time corresponds to the predetermined reading time. For the rest (Remaining) share of the reading time is granted time credit to the reader, i. H., if the consumer views the same page again, it will follow Only then does a new orientation time expire Page usage fee calculated when the credited remaining share time has expired. It is also possible for everyone to stop reading prematurely time credits created on a page in a user-specific time credit Collect account. Additional pages can then be used free of charge from this account to be viewed as.

The device tariffs are particularly time-dependent activation tariffs Consider, for example, a specific individualized device for 24 Hours to use any work is unlocked.

Even if the aspect shown deals with a technical infrastructure, a fair and fine-grained accounting for the use of digital content by the Enables consumers, but this understandably excludes them Classifications based on lump sums are not excluded ("flat rate"). this applies for both factory tariffs and device tariffs.

accounting

• - Zum einen kann für den Konsumenten eine rechnungsartige Aufstellung der von ihm beispielsweise in einem Abrechnungszeitraum getätigten Nutzungsvorgänge digitaler Inhalte aufbereitet werden, aus denen er die Zusammensetzung des Endbetrages ersehen kann.
• - Zum anderen kann für die Inhalteanbieter eine Aufstellung darüber erbracht werden, wie oft und gegebenenfalls auch zu welchen Tarifen bestimmte ihrer digitale Inhalte genutzt worden sind und welche Gesamtvergütung sich hieraus zugunsten des Inhalteanbieters errechnet.

A sixth aspect in connection with the invention is that the use of the digital content is billed on the basis of the pricing models. During billing, a specific amount to be paid by the consumer in a currency recognized as a means of payment or as a fraction or multiple of other units of value is determined on the basis of the details of the usage activities carried out by the consumer on the basis of the applicable pricing model. Two sub-aspects are particularly important for billing:

• - On the one hand, an invoice-like list of the usage processes of digital content, for example in a billing period, can be prepared for the consumer, from which he can see the composition of the final amount.
• - On the other hand, the content provider can be provided with a list of how often and if so at what tariffs certain of their digital content has been used and which total remuneration is calculated in favor of the content provider.

The solution according to the invention therefore makes it possible to use it digitally Content not only towards consumers, but also towards consumers Content providers based on facts and without billing.

status rights

• - Konsumentenspezifische Statusrechte, d. h. bestimmte Statusrechte sind an die Identität des Konsumenten oder gegebenenfalls an eine pseudonyme Identität des Konsumenten gebunden, nicht jedoch an einen bestimmten digitalen Inhalt ("Werk"). Ein Beispiel für diese Kategorie von Statusrechten bilden in der Vergangenheit insgesamt getätigte Umsatzsummen, die beispielsweise als Grundlage für eine Rabattgewährung herangezogen werden können.
• - Konsumentengebundene werkspezifische Statusrechte, d. h. diese Statusrechte sind gleichzeitig sowohl an die Identität des Konsumenten oder an dessen pseudonyme Identität als auch an eine einen digitalen Inhalt ("Werk") repräsentierende Datei gebunden. Ein Beispiel für diese Kategorie von Statusrechten bildet eine werkspezifische Aussage, dass ein bestimmter Konsument ein bestimmtes seitenorientiertes Textwerk bereits derart umfangreich genutzt hat, dass ihm nunmehr tarifgemäß das Recht zukommt, dieses Textwerk ohne weitere Einschränkungen und ohne weitere Berechnung von Nutzungshandlungen nutzen zu dürfen.
• - Konsumentengebundene werkspezifische Statusrechte können auch an eine Gruppe von Werken gebunden sein, beispielsweise alle Werke, die von einem bestimmten Inhalteanbieter, beispielsweise von einem bestimmten Verlag, vermarktet werden.
• - Konsumenten- und werkgebundene Substatusrechte. Diese Statusrechte sind nicht nur an die Identität oder Pseudonymität eines bestimmten Konsumenten, sondern auch darüber hinaus an einen bestimmten Teil eines Werkes gebunden. Ein Beispiel für diese Kategorie von Statusrechten ist das einem bestimmten Konsumenten zukommende Recht, bei der Nutzung eines bestimmten seitenorientierten Textwerkes bestimmte Einzelseiten des Werkes ohne zusätzliche Nachberechnung nutzen zu dürfen, da für die Nutzung dieser Seiten in der Vergangenheit bereits ein maximales tarifgemäßes Entgelt entrichtet worden ist.

A seventh aspect in connection with the invention is to store data features corresponding to status and privilege rights (“privileges”) that the consumer can acquire by executing usage transactions that are enabled and billed via the card. For example, it can be provided that the user can use those pages of a text work without further payment that he has used in the past with sufficient payment. Provision can also be made to grant discounts to the consumer depending on previously used processes. Status rights can be granted in particular at the following levels:

• - Consumer-specific status rights, ie certain status rights are linked to the identity of the consumer or, if applicable, to a pseudonymous identity of the consumer, but not to a specific digital content ("work"). In the past, an example of this category of status rights is the total amount of sales that can be used, for example, as the basis for granting a discount.
• - Consumer-related work-specific status rights, ie these status rights are simultaneously bound both to the identity of the consumer or to his pseudonymous identity and to a file representing a digital content ("work"). An example of this category of status rights is a work-specific statement that a certain consumer has already used a certain page-oriented text work to such an extent that he now has the right to use this text work according to the tariff without further restrictions and without further calculation of usage actions.
• - Consumer-related work-specific status rights can also be linked to a group of works, for example all works that are marketed by a certain content provider, for example by a certain publisher.
• - Consumer and work-related sub-status rights. These status rights are not only linked to the identity or pseudonymity of a certain consumer, but also to a certain part of a work. An example of this category of status rights is the right that a certain consumer has to be allowed to use certain individual pages of the work when using a certain page-oriented text work without additional recalculation, since a maximum tariff-based fee has already been paid for the use of these pages in the past ,

• - Auszahlung von Geldbeträgen oder sonstigen Werteinheiten, gegebenenfalls auch bei Verrechnung mit bestehenden Forderungen aus anderen bereits getätigten oder zukünftig zu tätigenden Nutzungsvorgängen des Konsumenten;
• - unentgeltliche Nutzung bestimmter digitaler Inhalte mit oder ohne zeitliche Beschränkungen;
• - Rabatte bei anderen Akten des Medienkonsums durch den Konsumenten, beispielsweise bei Kinobesuchen, Festivalbesuchen etc., wobei insbesondere verschiedene Vermarktungsformen ein und desselben Werkes gekoppelt werden können, etwa bei Rabattgewährung bei herkömmlichem Buchkauf, wenn der zum Buch gehörige Film mittels der erfindungsgemäßen Lösung digital konsumiert worden ist;
• - Abgabe eines körperlichen Datenträgers mit bestimmten digitalen Werken, beispielsweise einer CD-ROM mit einem bestimmten Musiktitel, wenn dieser hinreichend oft (d. h., mindestens eine vorbestimmte Anzahl von Vorgängen) entgeltpflichtig über die erfindungsgemäße Lösung konsumiert worden ist.

Status rights each establish a right of the beneficiary consumer to a certain service, which, depending on the circumstances of the individual case, can be provided, for example, by the content provider or by the operator of the portal data processing device. The following services are particularly considered:

• - Payment of monetary amounts or other units of value, possibly also when offset against existing claims from other consumer transactions that have already been carried out or will be carried out in the future;
• - free use of certain digital content with or without time restrictions;
• - Discounts on other files of media consumption by the consumer, for example when visiting the cinema, visiting a festival, etc., whereby in particular various forms of marketing of the same work can be coupled, for example when granting discounts for conventional book purchases, if the film belonging to the book is digitally consumed using the solution according to the invention has been;
• - Delivery of a physical data medium with certain digital works, for example a CD-ROM with a certain music title, if this has been consumed sufficiently often (ie, at least a predetermined number of processes) for a fee via the solution according to the invention.

• - offline erfolgen, d. h. die beim Konsumenten betriebene Vorrichtung ermittelt aus den Verbrauchsdaten unmittelbar anhand der Verbrauchschronik die dem Konsumenten zustehenden Statusrechte, oder
• - online erfolgen, d. h., die Portal-Datenverarbeitungsvorrichtung ermittelt die dem Konsumenten zukommenden Statusrechte erst nachdem die Verbrauchschronik durch den Konsumenten von der durch diesen betriebenen Vorrichtung zur Portal-Datenverarbeitungsvorrichtung übertragen worden ist.
  Bei dieser Variante besteht der Vorteil, dass der Konsument animiert wird, möglichst häufig eine Online-Verbindung zur Übertragung der Verbrauchschronik herzustellen.

The acquisition of status rights based on a consumption history can

• - take place offline, ie the device operated by the consumer determines the status rights to which the consumer is entitled from the consumption data directly on the basis of the consumption history, or
• - take place online, ie the portal data processing device determines the status rights attributed to the consumer only after the consumption history has been transferred by the consumer from the device operated by the latter to the portal data processing device.
  This variant has the advantage that the consumer is encouraged to establish an online connection for the transmission of the consumption history as often as possible.

payment methods

• - anonym, d. h. ohne Kenntnis der Identität des Konsumenten und ohne Möglichkeit, durch Rückgriff auf einen Ersatznamen ("Pseudonym") mehrere Mediennutzungsvorgänge verknüpfen zu können,
• - pseudonym, d. h. ohne Kenntnis der Identität des Konsumenten, jedoch mit der Möglichkeit, durch Rückgriff auf einen Ersatznamen ("Pseudonym") mehrere Mediennutzungsvorgänge verknüpfen zu können, als auch
• - unter voller Aufdeckung der Identität des Konsumenten, d. h. unter Aufdeckung von Name und Anschrift des Konsumenten,

möglich ist. An eighth aspect in connection with the invention consists in the fact that the payment of the fees incurred can on the one hand be adapted to known payment systems that have been introduced on the market, but on the other hand preferably by means of technical arrangements

• - anonymously, ie without knowing the identity of the consumer and without being able to link several media usage processes by using a substitute name ("pseudonym"),
• - pseudonym, ie without knowing the identity of the consumer, but with the possibility of being able to link several media usage processes by using a substitute name ("pseudonym")
• - fully revealing the identity of the consumer, ie revealing the name and address of the consumer,

is possible.

• - Bezahlung auf Guthabenbasis, d. h. der Konsument muß vor Aufnahme der Konsumhandlungen einen Geldbetrag hinterlegen, wobei durch technische Sperren keine weitere Nutzung ermöglicht wird, sobald der Guthabenbetrag aufgebraucht ist, oder
• - Bezahlung auf Kreditbasis, d. h. der Inhalteanbieter oder der Betreiber der Portal-Datenverarbeitungsvorrichtung tritt in Vorleistung, indem dem Konsumenten die Nutzung ohne vorherige Hinterlegung eines Guthabens ermöglicht wird, wobei die Bezahlung nach der Abrechnung durch den Konsumenten zu erfolgen hat.
• - Auch bei Bezahlung auf Kreditbasis kann vorgesehen sein, dass ab einem bestimmten Kreditbetrag eine technische Sperre weitere Nutzungshandlungen seitens des Konsumenten unterbindet.

In the context of the solution according to the invention, the following can in particular be provided:

• - Payment on a credit basis, ie the consumer must deposit an amount of money before commencing consumption, whereby no further use is made possible due to technical barriers as soon as the credit amount has been used up, or
• - Payment on a credit basis, ie the content provider or the operator of the portal data processing device makes advance payment in that the consumer is able to use it without first depositing any credit, the payment having to be made after the billing by the consumer.
• - Even when paying on a credit basis, it can be provided that a technical block prevents further usage by the consumer from a certain loan amount.

In principle, payment can be processed via conventional channels such as Credit card, direct debit or bank transfer can be made. Especially However, a variant of the solution according to the invention proves advantageous the payment process with the participation of a card module (see above, third Aspect). Here, the data regarding the with the Consumers have digitally stored the agreed payment method on the card module are used and by using techniques of online payment become.

Reduced complexity "appliances"

A ninth aspect in connection with the invention is the use Reduced complexity usage devices ("Appliances") to digital content to make it perceptible to the consumer. Have been for some time networked through the Internet or other telecommunications systems Data processing facilities not only from companies, but also from End consumers in the context of "electronic commerce" ("e-commerce") Processing of all kinds of business.

Use of the Internet and other telecommunications systems such as for example, proprietary online systems are almost done by the end user always using a "personal computer", also called "PC", or a comparable device, for example a workstation, a portable one Computers ("Notebook") or a mini device to be held in one hand ( "Palmtop").

Personal computers and similar devices have the advantage that the Extent of functionality provided by it to the end user can be determined not only by the hardware used, but by by loading different programs at any time can be changed extremely flexibly. For example, it is possible subsequently install and install certain software if the End users would like to use additional functionalities.

The disadvantage of this universality is the excessive complexity of usual operating systems like Windows or Unix equipped PCs or Workstations. The end user must first have a considerable amount Background knowledge of the structure and functional relationships of the acquire complex overall system in order to realize the potential To be able to use universality to solve specific tasks in practice.

It turns out that not insignificant groups of end users or prospective end users telecommunications services therefore especially for Purposes of e-commerce do not want to or can not use because they use the Unable to master the complexity of PCs or comparable devices are, their use so far de facto a necessary prerequisite for the Participation in or use of telecommunications services.

For the end user in conventional data processing equipment The technical problems that arise are diverse. They usually start that not only set up the operating system, but also one Connection to a telecommunication system, for example the Internet, configured and finally manufactured. The modalities of the Access to the Internet varies locally, depending on the country or Region and moreover in the same place from provider to provider.

Finally, if an operational networked data processing device has been achieved, the end user sees one on the Internet, for example unstructured variety of offers for doing business. With conventional data processing equipment, the end user must develop and acquire extensive local knowledge themselves in order to find the for to be able to use interesting offers via the telecommunications network.

Finally, the end user has found a provider to do business with want to connect more closely, so are usually with any provider numerous special features regarding identification and authentication of the customer as well as the delivery of the ordered goods and payment processing to consider.

Given this problem, it has been proposed so far, extremely to create specialized data processing facilities that only one to provide only functionality or at most a few functionalities capital. An example of this is the cell phone, the one on one Represents telecommunications network coupled data processing device, which essentially has only one purpose, namely the Telephoning is used. A restriction to a single functionality each Device type, however, is proving itself with the increasing importance of networked Data processing equipment as a hindrance because the number of for the different types of use require different device types rises sharply. With an increase in the number of functionalities per device along conventional procedures, for example by adding Text message retrieval on mobile phones is quickly becoming a level of complexity again achieved in terms of device operation, which for broad user groups acts as a deterrent.

An important field of application of e-commerce is related to the distribution of files, the data processing programs, texts, May include images, multimedia works or video animations, through content providers to customers. There is one in this field of application Peculiarity is that the exchange of services between content providers and Customer can run completely disembodied, because both the offer catalog and the Order process, delivery of the ordered goods as well as billing in Form of data exchanged via telecommunications equipment can be handled. A disadvantage of previous approaches to distribution of works is that the customer is usually one Must acquire a copy of the work as a purchase, even if it is only uses it temporarily or in part.

The invention is therefore related to one for such purposes appropriate technical infrastructure.

telecommunications cards

A tenth aspect related to the invention is the approach the technical infrastructure according to the invention for distribution, billing and Payment for digital media content including a card module in the Connection with SIM cards and similar devices in To implement mobile communication radio networks, such as GSM or UMTS. As a result, the functionality of a telecommunications card can be advantageous Way with the functionality of multimedia consumption by this also serves as a card module.

• - die Verbreitung digitaler Inhalte über ein Mobilfunknetz,
• - die Abrechnung des Konsums digitaler Inhalte, gegebenenfalls unter Mitwirkung eines durch das Mobilfunknetz erreichbaren Abrechnungsservers, sowie
• - die Bezahlung konsumierter und abgerechneter digitaler Inhalte insbesondere unter Mitwirkung des Telekommunikationsanbieters, in einer für den Konsumenten transparenten Art und Weise in einer einzigen Anwendungsvorrichtung ("Appliance") zusammenzufassen.

The advantage conveyed by this aspect is, above all, that such a multifunction card enables

• - the distribution of digital content via a mobile network,
• - the billing of the consumption of digital content, possibly with the participation of a billing server that can be reached via the mobile network, and
• - The payment of consumed and billed digital content, in particular with the participation of the telecommunications provider, in a manner transparent to the consumer in a single application device ("appliance").

Although the present invention uses digital content distribution Distribution does not exclude physical data carriers, so it becomes a disembodied one Transfer in terms of minimizing business Transaction costs more important. This requires a suitable digital one Wide area network (WAN). By definition, mobile devices provide access to a digital world traffic network in the form of a digital cellular network represents.

Although the disembodied distribution of digital content by means of wired wide area networks in the context of the present invention such a wireless transmission appears to be entirely possible For example, using a cellular network is particularly advantageous since the In this case, the consumer can carry out his consumption file without being involved wired and therefore not available everywhere Network infrastructure.

The identity or at least pseudonymity of a consumer is that Telecommunications provider that issues the SIM card known. With SIM Cards that are used on a credit basis without a credit amount must be issued by the Telecommunications providers already for billing purposes at least that Know his customer's name and billing address. at The telecommunications provider often has credit-providing SIM cards about information about a specific payment method, for example in the form of a direct debit authorization, amounts due by direct debit from one certain account.

For SIM cards that are prepaid by the telecommunications provider "Prepaid" credit cards are issued, the fees for the Use of digital content from that managed by the telecommunications provider Credit amount will be debited. In principle, pseudonyms or even anonymous services are technically possible. As for the territory of the Federal Republic of Germany comes a pseudonymous or even Anonymous issuance of SIM cards for GSM networks based on relevant Provisions of the telecommunications law not considered, which the empowered users to monitor the Enable telecommunications traffic. Abroad this can However, the situation may be different in individual cases.

Video on demand

There is an eleventh aspect in connection with the solution according to the invention in the approach, a specific appliance for distribution, billing and Provide payment for digital content as video on demand. For example this can take the form of a so-called "set-top box", i.e. H. one Converter device between a cable television network and a television set happen. This set-top box can also be used to adapt analog TV channels be provided with a digitizing device, for example by means of a so-called "frame grabber" device that represents a television field Analog signal is recognized, sampled and digitized.

Play and order

A twelfth aspect relates to a particularly suitable solution for ordering and playing Works and can be realized with an independent inventive idea. Traditionally, intangible works are a. to select via the Internet and to download or stream. Via broadcast it is possible to go to predetermined Times to broadcast certain works encrypted or unencrypted in real time and make it available to the consumer when certain conditions are met. This However, the content provider incurs considerable costs if, for example, films Should be delivered on demand. Because in this case the same film is delayed must be sent over several channels in order to achieve the quasi "on demand effect" for the Realizing consumers is not only overusing the air interface, but the Transmission is still ineffective. The invention is based on the idea of Corresponding channels only illustrative material in the form of trailers or in short form with an application to broadcast as many works as possible in one time To encourage consumers. This is already being done for radio broadcasts anyway, since the Broadcasters must earn their money through advertising revenue. By a suitable one technical device at the consumer can such works with appropriate clear identifiability, for example through verbal or written information of a presenter or technically by adding a work identifier in the broadcast Work (similar to that on the car radio) marked by input on the device become. With the marking of certain works, for example, corresponding filters set up on the receiving part of the device. The trailer can be broadcast over days at multiple intervals. It can be pieces of music (radio), games (Game show), films (video trailer), etc.

At a later time or on a different channel you can change the If necessary, only work in full in the same order of presentation this time Length compressed and encrypted via broadcast to a wide range of consumers be transmitted simultaneously. The preset device at the consumer selects the desired works by filtering them out unwanted works and saves them to a suitable, intended one Storage medium. Is the user through appropriate rights, for example over a rights card (smart card) legitimizes it, so it is able to stored Works to consume. Preferably, fees only fall on an actual one Use of the works. The order of the works can also be done on the Internet or Be done offline, with the delivery of the works being addressed in this case.

Consumable data transfer on the part of the consumer

A twelfth aspect in connection with the solution according to the invention consists in the approach to provide technical arrangements that are suitable and are intended, personal data from the area of the consumer, for example, regarding its consumption habits, to the operator of the To transmit portal data processing system or to individual content providers, in return for using this data in return for the consumer Status rights is remunerated.

Fig. 1 shows schematically an inventive networked data processing means having a server portion 110 and a client portion 120. The server part 110 and the client part 120 are connected to one another for the exchange of data via a telecommunications network 130 referred to as a WAN (Wide Area Network), for example via the analog telephone network, the ISDN network, the Internet or a satellite link. Typically, server part 110 and client part 120 are each assigned a unique address or identifier 112 , 122 for the purpose of data exchange via WAN 130 , for example a telephone number, an Internet address or the like. If the client part 120 wants to establish a connection to the server part 110 via the WAN 130 , it needs information about its address 112 . Conversely, the server part 110 requires information about the address 122 of the client part 120 .

The client part 120 is set up to receive a mobile card module 140 . The card module 140 comprises at least one storage device for the non-volatile storage of data (not shown) and can exchange data with the client part 120 via a data communication device (not shown). The card module 140 can in particular be designed as a chip card; however, other easily transportable designs are also possible. Basic properties of chip cards are known, among others, in Wolfgang Rankl and Wolfgang Effing: "Manual of chip cards", Munich: Carl Hanser Verlag, 2nd edition 1996. The disclosure content of this document is incorporated into the present description by reference. A card module 140 that can be used as a double-sided chip card is particularly preferred. For example, one side of the chip card can be designed by a media content provider (content provider) who issues this card to its customers. When the card is inserted with this side up into a terminal, a preferred connection to a selection page of this provider is established. The other side is designed, for example, by the operator of the portal data processing device. When this side of the card is inserted upward, a connection to a register and / or a search engine of this operator of the portal data processing device is preferably provided, which enables a media content provider to select works independently. However, there is preferably at least one link to the operator of the portal data processing device on the specific page of the media content provider occupying the card page, so that the user does not have to remove the card and turn it over, but also by clicking on a link -Buttons can switch to other providers and their media offerings.

The server part 110 is a computer that is typically associated with a commercial provider of goods and / or services. The server part 110 can be, for example, a computer coupled to the telephone network via modem or ISDN, which can be dialed from the client part 120 via a dial-up line connection for data communication. In another embodiment, the server part 110 is an Internet-connected “World Wide Web” server (“WWW server”) that can communicate with the client part 120 via the “Hypertext Transport Protocol” (“HTTP protocol”). In a further embodiment, the server part is designed, for example, as a computer connected to the Internet which uses the "Simple Mail Transport Protocol"("SMTP") and the "Post Office Protocol"("POP") to send electronic mail ("e-mail ") can exchange with the client part 120 . The invention is not limited to certain types of telecommunication networks or to certain protocols; The above information is only used for illustration.

• - Aspekt (1): Zum einen ermöglicht das Kartenmodul 140 im Zusammenwirken mit dem Clientteil 120 einen systemunabhängigen Aufbau der Kommunikationsbeziehung zum Serverteil 110, beispielsweise durch einen systemunabhängigen Einwählvorgang. Dazu werden Zugangsdaten, Zugangskonfigurationen oder Zugangsprozeduren im Speicher des Kartenmoduls 140 abgespeichert. Dies erspart dem Endbenutzer eine aufwendige Konfiguration der Zugangsdaten beispielsweise zu einem Internet- Zugangsprovider, zu einem Server für elektronische Post oder zu einem Server zur Abwicklung elektronischer Abonnements. In einer bevorzugten Variante kann der Clientteil 120 mit dem Kartenmodul 140 derart ausgestaltet sein, dass der Endbenutzer lediglich das Kartenmodul 140 in den Clientteil 120 einstecken muß, um den Aufbau einer Telekommunikationsverbindung zu einem Serverteil 110 zu initiieren. Dort, wo es angezeigt ist, kann die Initiierung des Aufbaues einer Telekommunikationsverbindung zu dem Serverteil 110 zusätzlich von der Betätigung eines Bedienelementes insbesondere am Clientteil 120 und/oder von der Eingabe einer Sicherheitsinformation, beispielsweise einer PIN, abhängig gemacht werden.
• - Aspekt (2): Das Kartenmodul 140 ermöglicht im Zusammenwirken mit dem Clientteil 120 die Unterscheidung und/oder Identifikation des Endbenutzers gegenüber dem Serverteil 110. Hier bei sind drei Fälle zu unterscheiden: Zum einen kann es Fälle geben, bei denen eine Identifikation des Endbenutzers mit Namen, Adresse usw. nicht erforderlich oder nicht wünschenswert oder gesetzlich nicht zulässig ist, bei denen aber dennoch verschiedene Endbenutzer, die jeweils über gesonderte Kartenmodule 140 verfügen, voneinander unterscheidbar sein sollen. Dies kann einerseits durch eine reine Serialisierung des Kartenmoduls 140 beispielsweise mittels einer in einen nicht überschreibbaren Speicherbereich des Kartenmoduls 140 eingeschriebenen eindeutigen, sich nie wiederholenden Seriennummer geschehen; wenn der Endbenutzer nacheinander verschiedene Kartenmodule 140 mit verschiedener Seriennummer verwendet, kann ohne zusätzliche Verknüpfungsinformationen nicht auf die Person des Endbenutzers rückgeschlossen werden. Eine dritte Variante beinhaltet eine pseudonyme Identifikation des Endbenutzers über mehrere Kartenmodule 140 hinweg, die jedoch ohne zusätzliche Informationen keinen Rückschluß auf die Identität des Endbenutzers zuläßt. Bei vorbezahlten Kartenmodulen 140 wird häufig auf eine Identifikation des Endbenutzers verzichtet werden können. Wenn eine Zahlungsabwicklung über Rechnungsstellung, Kreditkarte, Lastschrift etc. vorgesehen ist, werden in der Regel Daten zur vollen Identifizierung des Endbenutzers erforderlich sein. Ein Pseudonym ist stets dann sinnvoll, wenn der beabsichtigte Leistungstausch auch ohne Kenntnis der Identität des Endbenutzers, aber unter Berücksichtigung des Wissens, welche verschiedenen Kartenmodule 140 ein und demselben Endbenutzer zuzuordnen sind, abgewickelt werden soll (siehe auch insbesondere Aspekt 7).
• - Aspekt (3): Auch ermöglicht das Kartenmodul 140 im Zusammenwirken mit dem Clientteil 120 seine Authentikation gegenüber dem Serverteil 110, d. h., es können bestimmte Echtheitseigenschaften eines Kartenmoduls 140 vom Serverteil aus überprüft werden. Hierzu können bevorzugt bekannte kryptographische Verfahren herangezogen werden. Beispielsweise ist es möglich, in einen einbruchssicher gestalteten ("tamper-proof") nichtflüchtigen Bereich des Speichers (nicht dargestellt) des Kartenmoduls 140 einen einem bestimmten Endbenutzer zugeordneten geheimen kryptographischen Schlüssel zu speichern. Der kryptographische Schlüssel muß jedoch nicht in jedem Fall einem Endbenutzer zugeordnet sein; es ist auch möglich, mit denselben Techniken von einem autorisierten Hersteller befugterweise in den Verkehr gebrachte Kartenmodule 140 von solchen Kartenmodulen zu unterscheiden, die von unbefugten Dritten nachgemacht worden sind.
• - Aspekt (4): Ferner ermöglicht das Kartenmodul 140 im Zusammenwirken mit dem Clientteil 120 die Steuerung zeitlich wiederkehrender Transaktionen gegenüber dem Serverteil 110, insbesondere Abonnements bestimmter Leistungen.
• - Aspekt (5): Weiterhin ermöglicht das Kartenmodul 140 im Zusammenwirken mit dem Clientteil 120 eine Kartenmodulgebundene Entschlüsselung von durch den Serverteil 110 gelieferten Dateien, die beispielsweise Software, Texte und/oder multimediale Werke repräsentieren können. Da durch läßt sich ein wirksamer technischer Schutz von Urheberrechten erreichen.
• - Aspekt (6): Das Kartenmodul 140 ermöglicht im Zusammenwirken mit dem Clientteil 120 ferner eine nach Zeittakt bemessene Nutzung von durch den Serverteil 110 gelieferten Dateien, die beispielsweise multimediale Werke repräsentieren können. Dadurch kann eine technische Infrastruktur zur nutzungszeitabhängigen Berechnung von Urheberrechten realisiert werden (siehe auch insbesondere Aspekt 7).
• - Aspekt (7): Auch ermöglicht das Kartenmodul 140 im Zusammenwirken mit dem Clientteil 120 die Abwicklung von Zahlungsvorgängen gegenüber dem Serverteil 110 beispielsweise durch Übertragung von Kreditkartennummern oder digitalen Wertzeichen ("Digital Cash"). Dabei sind verschiedene Alternativen zu unterscheiden: Zum einen kann ein in den Verkehr gebrachtes Kartenmodul 140 ein vorbestimmtes vorbezahltes Guthaben verkörpern, das durch ein entsprechendes, in dem Speicher (nicht dargestellt) des Kartenmoduls abgespeichertes vorbestimmtes Datenelement repräsentiert wird. Zum anderen kann die Zahlung personenbezogen durch Rechnungsstellung, Kreditkarte oder Lastschrift erfolgen, wobei die notwendigen Angaben zur Identität und die Zahlungsverkehrsdaten (Kontonummer, Kreditkartennummer, Rechnungsadresse etc.) in dem Speicher (nicht dargestellt) des Kartenmoduls 140 abgespeichert sind. Für beide Fälle ist es vorteilhaft, die Authentizität des Kartenmoduls 140 und der in seinem Speicher abgelegten Datenelemente mit einer von der befugten ausgebenden Stelle erzeugten digitalen Signatur abzusichern. Unabhängig von der vorstehenden Unterscheidung zwischen vorbezahltem Guthaben und laufender Abrechnung besteht eine Alternative zwischen einem Erwerb von Dateien nach dem Prinzip des Kaufes, d. h. nach einmaliger Entrichtung eines Kaufpreises besteht eine zeitlich unbeschränkte Nutzungsmöglichkeit, und einer Abrechnung nach Nutzungsintensität, vorzugsweise gemessen an der Nutzungszeit oder an dem Volumen tatsächlich genutzter Daten einer Datei. Schließlich besteht eine weitere unabhängige Alternative zwischen Kartenmodulen 140, die bereits zu dem Zeitpunkt, in dem sie in den Verkehr gebracht werden, mit allen erforderlichen abrechnungsbezogenen Datenelementen versehen sind, und solchen Kartenmodulen 140, bei denen die abrechnungsbezogenen Datenelemente erst nach der Abgabe an den Endbenutzer von dem Serverteil 110 zum Speicher (nicht dargestellt) des Kartenmoduls 140 übertragen werden. Die aus der Kombination dieser drei Alternativen herrührenden acht Einzelfälle bedingen jeweils eine bestimmte technische Ausgestaltung des Kartenmoduls und seiner Interaktion im Rahmen der erfindungsgemäßen Lösung.
• - Aspekt (8): Wenn das Kartenmodul 140 mit genügend Speicherkapazität beispielsweise in Gestalt von sogenanntem Flash-Speicher ausgestattet ist, können Dateien, die beispielsweise Programme für Datenverarbeitungsanlagen, Texte oder multimediale Werke repräsentieren, in dem Kartenmodul zeitweise oder dauernd abgelegt werden. Dadurch wird insbesondere die technische Realisierung von bereits in Aspekt (4) angesprochenen Systemen zum automatisierten periodischen Bezug von Software, Texte und/oder multimediale Werke repräsentierenden und durch den Serverteil 110 distributierten Dateien verbessert.
• - Aspekt (9): Schließlich kann das Kartenmodul 140 im Zusammenwirken mit dem Clientteil 120 dazu herangezogen werden, bestimmte Funktionalitäten durch den Serverteil 110 telematisch freizugeben oder zu sperren.

FIG. 2 shows a schematic illustration of various aspects in the commercial use of a data processing device according to the invention. The interaction of the card module 140 with the client part 120 according to the invention enables the end user (not shown) who accesses the server part 110 via the client part 120 to carry out transactions advantageously.

• - Aspect (1): On the one hand, the card module 140, in cooperation with the client part 120, enables a system-independent establishment of the communication relationship with the server part 110 , for example by means of a system-independent dial-in process. For this purpose, access data, access configurations or access procedures are stored in the memory of the card module 140 . This saves the end user from having to configure the access data, for example, to an Internet access provider, to a server for electronic mail or to a server for processing electronic subscriptions. In a preferred variant, the client part 120 can be configured with the card module 140 in such a way that the end user only has to insert the card module 140 into the client part 120 in order to initiate the establishment of a telecommunication connection to a server part 110 . Where it is indicated, the initiation of the establishment of a telecommunications connection to the server part 110 can additionally be made dependent on the actuation of an operating element, in particular on the client part 120, and / or on the entry of security information, for example a PIN.
• - Aspect (2): The card module 140 , in cooperation with the client part 120, enables the end user to be distinguished and / or identified from the server part 110 . There are three cases here: Firstly, there may be cases in which an identification of the end user by name, address, etc. is not required or not desirable or not permitted by law, but nonetheless in which different end users, each using separate card modules 140 , should be distinguishable from each other. This can be done on the one hand by a pure serialization of the card module 140, for example by means of a unique, never repeating serial number written into a memory area of the card module 140 that cannot be overwritten; if the end user successively uses different card modules 140 with different serial numbers, the end user cannot be inferred without additional link information. A third variant includes a pseudonymous identification of the end user across several card modules 140 , which, however, does not allow any conclusions to be drawn about the identity of the end user without additional information. With prepaid card modules 140 , an identification of the end user can often be dispensed with. If payment processing via invoice, credit card, direct debit, etc. is provided, data will generally be required to fully identify the end user. A pseudonym always makes sense if the intended exchange of services is to be carried out without knowing the identity of the end user, but taking into account the knowledge of which different card modules 140 can be assigned to the same end user (see also in particular aspect 7 ).
• - Aspect (3): In cooperation with the client part 120 , the card module 140 also enables its authentication to the server part 110 , ie certain authenticity properties of a card module 140 can be checked from the server part. Known cryptographic methods can preferably be used for this. For example, it is possible to store a secret cryptographic key assigned to a specific end user in a tamper-proof non-volatile area of the memory (not shown) of the card module 140 . However, the cryptographic key does not always have to be assigned to an end user; it is also possible, using the same techniques, to distinguish card modules 140 that are authorized to be placed on the market by an authorized manufacturer from card modules that have been copied by unauthorized third parties.
• - Aspect (4): Furthermore, the card module 140, in cooperation with the client part 120, enables the control of recurring transactions with the server part 110 , in particular subscriptions to certain services.
• Aspect (5): Furthermore, the card module 140, in cooperation with the client part 120, enables a card module-bound decryption of files supplied by the server part 110 , which files can represent software, texts and / or multimedia works, for example. As a result, effective technical protection of copyrights can be achieved.
• - Aspect (6): The card module 140 , in cooperation with the client part 120, also enables timed use of files supplied by the server part 110 , which can represent multimedia works, for example. This enables a technical infrastructure to be used for calculating copyrights based on usage time (see also in particular aspect 7 ).
• - Aspect (7): In cooperation with the client part 120 , the card module 140 also enables payment transactions to be processed with respect to the server part 110, for example by transferring credit card numbers or digital tokens ("digital cash"). Different alternatives are to be distinguished here: On the one hand, a card module 140 placed on the market can embody a predetermined, prepaid credit, which is represented by a corresponding, predetermined data element stored in the memory (not shown) of the card module. On the other hand, the payment can be made personally by billing, credit card or direct debit, the necessary information on identity and the payment transaction data (account number, credit card number, billing address etc.) being stored in the memory (not shown) of the card module 140 . In both cases, it is advantageous to secure the authenticity of the card module 140 and the data elements stored in its memory with a digital signature generated by the authorized issuing body. Regardless of the above distinction between prepaid credit and ongoing billing, there is an alternative between purchasing files according to the principle of purchase, i.e. after paying a purchase price once, there is unlimited use, and billing according to usage intensity, preferably measured in terms of usage time or the volume of data actually used in a file. Finally, there is another independent alternative between card modules 140 , which are already provided with all the necessary billing-related data elements at the time when they are placed on the market, and those card modules 140 , in which the billing-related data elements are only provided after delivery to the end user are transmitted from the server part 110 to the memory (not shown) of the card module 140 . The eight individual cases resulting from the combination of these three alternatives each require a specific technical configuration of the card module and its interaction in the context of the solution according to the invention.
• - Aspect (8): If the card module 140 is equipped with sufficient storage capacity, for example in the form of what is known as flash memory, files that represent programs for data processing systems, texts or multimedia works, for example, can be stored temporarily or permanently in the card module. This improves in particular the technical implementation of systems already mentioned in aspect ( 4 ) for the automated periodic acquisition of software, texts and / or multimedia works and files distributed by the server part 110 .
• - Aspect (9): Finally, the card module 140, in cooperation with the client part 120, can be used to telematically enable or block certain functionalities by the server part 110 .

In a data processing device according to the invention, not all of them have to Aspects to be realized at the same time.

The exemplary embodiments described below and their variants make use of certain cryptographic techniques such as for example asymmetrical cryptography and digital signatures. A An introduction to applied cryptography can be found, for example, in: Bruce Schneier: "Applied Cryptography", New York: John Wiley & Sons, Inc., 1994. The Disclosure content of this document is made by reference in the present Description added.

Fig. 3 with reference to a schematic view showing a first application of the invention, a data processing device according to the invention. As already shown in FIG. 1, a client part 120 is connected to a server part 110 via a WAN 130 . The client part 120 is provided with a display device 125 which is only shown schematically. The card module 140 received by the client part identifies a specific end user (not shown) to whom the card module 140 is assigned, personally or pseudonymously. In particular, identity information 141 is stored in the card module 140 and can be transmitted to the server part 110 via the WAN 130 . The identity information 141 can be additionally secured on the client part 120 side in the usual way, for example by a PIN or by biometric identity detection devices (not shown). In addition to the card module 140 , other card modules 140 a, 140 b, 140 c can exist, each of which is assigned to the identities SN1, SN2 or SN3. If the card module 140 belonging to the identity SN4 141 is exchanged for one of the other card modules 140 a, 140 b, 140 c, the respective assigned identity information SN1, SN2 or SN3 can be transmitted to the server part 110 . The first application of the invention shown in FIG. 3 is particularly important when an acting subject, for example in his capacity as a contractual partner, is to be at least distinguishable on the part of the server part 110 or else to be identifiable directly or via a pseudonym.

Fig. 4 with reference to a schematic view showing a second application of the invention, a data processing device according to the invention. As already shown in FIG. 1, a client part 120 is connected to a server part 110 via a WAN 130 . The client part 120 is provided with a display device 125 which is only shown schematically. The card module 140 received by the client part can identify, in particular via a predetermined data element, a specific contractual relationship AbD 141 , which in the present example includes the regular delivery (subscription) of a digital multimedia product. In addition to the card module 140 , other card modules 140 a, 140 b, 140 c can exist which are each assigned to the contractual relationships AbA, AbB or AbC ( 141 a, 141 b, 141 c). If the card module 140 belonging to the contractual relationship 141 is exchanged for one of the other card modules 140 a, 140 b, 140 c, the respective assigned contractual relationship information 141 a, 141 b or 141 c can be transmitted to the server part 110 . The respective contractual relationship information 141 , 141 a, 141 b, 141 c is a parameter which controls an automatic selection process with regard to the file (not shown) to be transmitted from the server part 110 to the client part 120 and a multimedia representation, and also with regard to the transmission time.

Fig. 5 shows a fourth application of the invention based on a schematic representation of a data processing device according to the invention. As already shown in FIG. 1, a client part 120 is connected to a server part 110 via a WAN 130 . The client part 120 is provided with a display device 125 which is only shown schematically. The card module 140 received by the client part identifies in particular a specific server part 110 , which can be assigned, for example, to an associated specific service provider SPr4. In addition to the card module 140 , other card modules 140 a, 140 b, 140 c can exist, which are each assigned to the service providers SPr1, SPr2 and SPr3 ( 141 a, 141 b, 141 c). If the card module 140 belonging to the service provider 141 is exchanged for one of the other card modules 140 a, 140 b, 140 c, the respective assigned service provider information 141 a, 141 b or 141 c can be transmitted to the server part 110 . The respective service provider information 141 , 141 a, 141 b, 141 c is a parameter which, in particular, brings about an automatic selection process with regard to the data transmission parameters from the client part 120 , so that an automatic initiation of a data exchange between client part 120 and server part 110 is made possible.

FIG. 6 shows a first variant of an embodiment of the solution according to the invention shown in FIG. 1. As already shown in FIG. 1, a client part 120 set up to receive a card module 140 is connected to a server part 110 via a WAN 130 . The client part 120 is provided with a display device 125 which is only shown schematically. FIG. 6 thus shows a solution in which the client part 120 set up to receive a card module 140 and the display device 125 form a device that is essentially mechanically made in one piece.

FIG. 7 shows a second variant of an embodiment of the solution according to the invention shown in FIG. 1. As already shown in FIG. 1, a client part 120 that is set up to accommodate a card module 140 is provided. The client part 120 is coupled via a data communication device 123 to a display device 125 , only shown schematically, which is connected to a server part 110 via a WAN 130 . Fig. 7 thus shows a solution, in which the appointed for receiving a card module 140 and client part 120, each forming the one hand and connected to the WAN 130 display device 125 on the other hand, a mechanically substantially made in one piece device for itself, wherein the data exchange between the client part 120 and the display part 125 by the data communication device 123 . As technical implementations for the data communication device, wireless and wire-bound devices and methods come into consideration, in particular by data transmission cable (not shown), by radio (not shown) or by infrared, e.g. B. IrDA (not shown).

FIG. 8 shows a third variant of an embodiment of the solution according to the invention shown in FIG. 1. As already shown in FIG. 1, a client part 120 is provided, which is configured to receive a card module 140 and is connected to a server part 110 via a WAN 130 . The client part 120 is coupled via a data communication device 123 to a display device 125 which is only shown schematically. Fig. 8 thus shows a solution in which to receive a card module 140 arranged and connected to the WAN 130 client part 120 on the one hand and the display device 125 on the other hand, each form a mechanically substantially made in one piece device for itself, wherein the data exchange between the client part 120 and the display part 125 by the data communication device 123 . As technical implementations for the data communication device, wireless and wire-bound devices are possible methods, in particular by data transmission cable (not shown), by radio (not shown) or by infrared, e.g. B. IrDA (not shown).

FIG. 9 shows a fourth variant of an embodiment of the solution according to the invention shown in FIG. 1. As already shown in FIG. 1, a client part 120 , which is set up to accommodate at least one card module 140 , is provided, which is connected to a server part 110 via a WAN 130 . In addition to the client part 120, there is a display device 125 , only shown schematically, which is also set up to accommodate at least one card module 140 . FIG. 9 thus shows a solution in which the client part 120, which is set up to accommodate a card module 140 and is connected to the WAN 130 , on the one hand, and the display device 125, on the other hand, each form a device that can be mechanically constructed in one piece, with the data exchange between the client part 120 and the display part 125 by plugging the card module 140 . For example, the card module can be included in the client portion 140 140 for storing supplied by the server portion 110 data. After the relevant data have been stored in the card module 140 , this data can be made perceptible by plugging the card module into the display device. Conversely, it is also possible, for example, to store data relating to ordering processes in the card module 140 if it has been recorded by the display device 125 . After the card module 140 has been plugged into the client part 140, this order data can be sent to the server part 110 via the WAN 130 .

FIG. 10 shows a fifth variant of an embodiment of the solution according to the invention shown in FIG. 1. As already shown in FIG. 1, a client part 120 that is set up to accommodate a card module 140 is provided. The client part 120 is coupled via a data communication device 123 to a display device 125 , only shown schematically, which is connected to a server part 110 via a WAN 130 . Fig. 10 therefore shows a solution, in which the appointed for receiving a card module 140 and client part 120 on the one hand and connected to the WAN 130 display device 125 each form the other hand, a mechanically substantially made in one piece device for itself, wherein the data exchange between the client part 120 and the display part 125 by the data communication device 123 . As technical implementations for the data communication device, wireless and wire-bound device methods come into consideration, in particular by data transmission cable (not shown), by radio (not shown) or by infrared, e.g. B. IrDA (not shown).

The client part 120 shown in FIG. 10 is set up to accommodate a plurality of card modules 140 a- 140 e, which can initiate and control communication processes with the server part 110 independently of one another by means of the card module data (not shown) stored on them, and which in the case of the Server part 110 initiated communication processes are independently addressable from the point of view of server part 110 .

For example, at least one of the card modules 140 a- 140 e can act as a component of a system shown in FIG. 4, ie one card module or several card modules serve as a memory for digitally delivered by the server part 110 via the WAN 130 regularly but asynchronously with respect to operator actions digital multimedia products.

The particularity of the arrangement shown in FIG. 10 compared to the arrangement shown in FIG. 7 is, in particular, that a master card module 140 is provided, with which the display device 125 differs in a special way from the client part 120 or the others used therein Can identify and authenticate card modules 140 a- 140 e. For example, the master card module 140 can be inserted into a digital book used as a display device 125 . The digital book is then set up by the master card module 140 in such a way that certain privileged operating processes can be carried out by the user via the data communication device 123 relative to the client part or the further card modules 140 a- 140 e used therein, for example the activation or blocking of the Client part 120 for deliveries by server part 110 or to carry out ordering processes with respect to server part 110 . For this purpose, the data communication via the data communication device 123 is preferably secured against tapping and manipulation by suitable techniques, in particular cryptographic techniques.

FIG. 11 shows a sixth variant of an embodiment of the solution according to the invention shown in FIG. 1. As already shown in FIG. 1, a client part 120 is provided for receiving a card module 140 , which is connected to a server part 110 via a WAN 130 . The client part 120 is coupled via a data communication device 123 to a display device 125 which is only shown schematically. Also Fig. 10 therefore shows a solution, in which the set up to receive at least one card module 140 and client part 120 on the one hand and connected to the WAN 130 display device 125 each form the other hand, a mechanically substantially made in one piece device for itself, wherein the data exchange between the client part 120 and the display part 125 by the data communication device 123 . The peculiarity of from that shown in Fig. 7 arrangement is shown in Fig. Assembly 11 shown in particular in that the client part 120 a- as well as in the example shown in Fig. 10 case, for receiving a plurality of card modules 140 140 e is established, the can initiate and control communication processes with the server part 110 independently of one another by means of the card module data (not shown) stored on them and which can be independently addressed from the point of view of the server part 110 in the case of communication processes initiated by the server part 110 . For example, at least one of the card modules 140 a- 140 e can act as part of a system shown in FIG. 4; ie one card module or several card modules serve as a memory for digital multimedia products supplied by the server part 110 via the WAN 130 regularly but asynchronously with respect to the operator's operating actions.

In the variant shown in FIG. 11, it proves to be particularly advantageous to implement the client part 120 as a stationary card module station which is essentially permanently connected to the WAN 130 and thus can always initiate data communication processes with respect to the server part 110 and, moreover, from the latter Server part 110 can receive initiated data communication processes asynchronously to user actions, even if the display device 125 is designed as a mobile device that the user carries with him even when he is away.

Both with regard to the variant shown in FIG. 10 and visibly the variant shown in FIG. 11, it can prove to be advantageous to design the display device 125 to accommodate at least one card module 140 , so that the one shown in FIG. 9 can be replaced by repositioning a card module Usage mode can be used.

While in the variants shown in FIGS . 6 to 11 the client part 120 is set up to accommodate at least one card module 140 , FIGS . 12 and 13 each show a variant in which a client part 120 without its own card module is used. FIG. 13 shows a client part 120 which is set up to receive a complete display device 125 , the display device 125 again being set up to receive at least one card module 140 . Data communication between server part 110 and card module 140 takes place in such a way that the exchanged data are passed through display device 125 by means of suitable electronic arrangements. Of course, it is not absolutely necessary for the client part 120 to be set up to accommodate a complete display device 125 . The data exchange between client part 120 on the one hand and display device 125 prepared for receiving at least one card module 140 on the other hand can also be implemented, for example, as shown in FIG. 13 by means of a data communication device 123 . As technical implementations for the data communication device, wireless and wire-bound devices are possible methods, in particular by data transmission cable (not shown), by radio (not shown) or by infrared, e.g. B. IrDA (not shown).

FIGS. 14 and 15 show further variants of embodiment illustrated in FIG. 1, the inventive solution. As already shown in FIG. 1, FIG. 14 also provides a client part 120 which is set up to receive a card module 140 and which is connected to a server part 110 via a WAN 130 . A display device 125 is also connected to the WAN 130 a. The WAN 130 can be identical to the WAN 130 a. An interaction with the server part 110 triggered by the display device 125 and transmitted via the WAN 130 a leads to the transmission of multimedia data from the server 110 via the WAN 130 to the client part 120 . As a result, the user (not shown) can, for example, call up data from the server part 110 while on the move, which data is transmitted via the WAN 130 to the client part 120 set up at home, for example.

Fig. 15 shows a variant in which the client part is provided with a display 125,120. The data retrieved from server part 110 (not shown) is transmitted via WAN 130 to a secondary client part 120 a.

Fig. 16 is a schematic block diagrammatic representation showing an inventive device 100 for distributing, billing and payment of digital media content.

Files 104 , 106 , 108 made available by content providers 102 are provided on a server 110 for distribution. The files are preferably distributed to individual client computers in encrypted form by downloading them from the Internet or by selling physical data carriers such as CDs, DVDs, flash memory, etc. (not shown). When dialing in to a service provider, certain works formats can be selected by means in the client computer or in the playback device, so that, for example, only MP3-compatible works are made available for downloading to an MP3 player. Using a personal computer or notebook or television with an Internet connection, all formats of distributable works could be viewed via certain categories for selection and ordering (download, upload, streaming or broadcast). The digital content made available to the client computer is represented symbolically and marked with the reference symbol 112 . The billing and payment of the fees for this digital content 112 is carried out by an exemplary function block 120 .

The function block 120 has a decoder 122 , which first decrypts the digital content cryptographically (reference symbol 124 ) and then makes it accessible to the sensible perception by the consumer 128 in a suitable technical manner. In the case of MP3 audio files, this can be done, for example, by generating an analog audio signal that can be reproduced with a loudspeaker 126 or headphones (not shown). In the case of other contents (for example texts, images, video; not shown), for example a visual display can also take place on a display device (not shown).

An evaluation device 130 is connected to the decoder 120 in order to continuously generate data for a consumption chronicle 132 during the media use by the consumer 128, which data describe the respective usage process with sufficient accuracy in order to be able to carry out billing later. The consumption chronicle contains, for example, data on the duration of use of an audio title or, in the case of other types of work (for example text; not shown), also data on used text pages and the individual times of use with regard to individual text pages. Other options for recording or measuring usage are also possible.

A limiter 134 is provided in order to continuously or at certain intervals depending on the calculation in the consumption history of the accumulated remuneration amount according to the data in the consumption chronicle 132 and to transmit a blocking signal 136 to the decoder 122 if predetermined remuneration amounts are exceeded. As soon as the decoder 122 receives the blocking signal 136 from the limiter 134 , the use of the encrypted content 112 is interrupted until the limiter 134 releases the blocking signal 136 . Instead of a fee, time credits or credit for usage volume are possible. Also a hybrid variant of the options described above.

A credit memory 140 stores a data value that represents a sum of money, an available usage time or an available usage volume, which the consumer 128 has deposited in order to cover future billing amounts, for example by prepayment in the form of a security. The credit memory 140 can be replenished by all common micro-payment systems. This includes, for example, Click & Buy, Paysafe (prepaid) or charging via a service number such as B. a 0190 number. When the credit is topped up using a 0190 number, certain credit values can be charged, for example, using various telephone numbers, which can be designed as end numbers for a master number, and billed via the telecommunications companies. Charging a credit memory, in particular for offline use of digital works, programs or the like, via a service number is an independent concept of the invention, for which protection is claimed independently. In particular, it is advantageously possible to top up a credit memory in a connectable payment module, for example a smart card, using a service number. This credit can in turn be a monetary credit, a time credit or a volume-related credit. Works-specific usage rights and / or privileges can also be set up using a service number.

The limiter 134 preferably fulfills its functionality in cooperation with the credit memory 140 , ie as long as there is credit, the decoder 122 is not blocked.

Function block 120 contains critical data and functionalities that must be protected against any unauthorized manipulation from outside, in particular by the consumer. The decryption key 123 is particularly sensitive, by means of which the decoder 122 cryptographically decrypts the data 112 representing the digital content and thus makes it accessible for further processing. The credit value (not shown) stored in the credit memory 140 is also highly sensitive. The consumption measurement 130 and the limiter 134 represent critical functionalities because manipulation of these devices can sabotage the intended payroll.

It is therefore advantageous to construct the function block 120 as a particularly protected ("tamper-proof") assembly. In the simplest case, the individual components of this assembly 120 can, for example, be embedded in a casting compound, for example synthetic resin. In further developed solutions, sensors (not shown) can be provided which are suitable for detecting inadmissible mechanical and / or electrical manipulations. The output signal of these sensors can then be used to instantly delete critical data such as cryptographic keys 123 or credit values in the credit memory 140 . The components credit memory 140 and / or limiter 134 , which in the exemplary embodiment shown in FIG. 16 are combined in a function block 120 , can also be contained in a separate module or modules which can be coupled to the function module 120 .

All of the components combined in the function module 120 can be implemented either as separate hardware components or as individual software modules or as a whole as a software solution, for example in the form of plug-ins for a browser.

The consumption history 132 also represents an aggregation of sensitive data that must be protected against manipulation. For this purpose, the memory (not shown) for storing the consumption history 132 can also be included in the protected function block 120 (not shown). Another possibility is to protect the data values of the consumption chronicle 132 against unauthorized changes by means of one or more digital signatures. For this purpose, a digital signature generation and verification component (not shown) is then provided, which is advantageously included in the protected critical function block 120 .

When the binding billing and payment is carried out, the data content of the consumption chronicle is transmitted to a billing server 145 in a suitable manner, preferably via a data network connection which is cryptographically secured against unauthorized eavesdropping and data manipulation. The billing server uses the data from the consumption history to calculate the fee to be paid by the consumer and posts the corresponding amount, for example, by debiting to a (shadow) account 150 assigned to the consumer. The consumer can then carry out a payment in a conventional manner, for example by bank transfer or via a credit card clearing house. Account 150 is not mandatory; If such payment systems are to be used which, like anonymous digital money (digital cash), do not require a (shadow) account 150 , the account 150 can be dispensed with.

After payment has been made or - if the consumer has a corresponding creditworthiness - even after billing has been carried out by the billing server 145 , the credit value stored in the credit memory 140 can be transmitted by the billing server 145 to the functional unit 120 or to the credit message 155 that is cryptographically secured against manipulation Credit memory 140 can be increased by a certain credit value.

The credit memory 140 is particularly preferably accommodated on a SmartCard in order to be able to use the stored credit value independently of the system and on other devices on the move. In this case, the function module 120 contains a smart card reader, not shown. The component containing the SmartCard reader can be designed, for example, as a PCMCIA card, which comprises the functionalities of the functional module 120 .

An alternative to FIG. 16, not shown, is the formation of a module that can be coupled to a playback device, preferably for plugging in, for example, PCMCIA, with an integrated memory in which, among other things, so-called players and / or playback licenses can be stored in such a way that when the module is coupled to another Playback device or computer the license can be used with corresponding playback or usage rights, and is not made unusable or invalid by using another playback device. Existing license solutions from other providers can be easily modified and / or the module can be provided in such a way that system-independent use of the license (s), the player (s) and / or the supplier's works by the module is not possible Copy of rights or credit licenses can be created. In a further embodiment (not shown), a smart card is designed with means such as a rights card that, in cooperation with a software license installed on a computer, it makes it possible to play correspondingly provided multimedia data (works). In particular, information for identification and / or verification of the authorization to use the license, the player and / or certain works is provided by means of the smart card. In a further development, a software license or a player can be modified in such a way that different users can use works or application programs etc. provided by means of their own smart card, without having to install a new license on the computer or playback device. Payment by smart card such. B. over monetary units, over the settlement with a time credit and / or a credit of usable data volume are possible. It is also possible to design the smart card as a debit and / or credit card.

FIG. 17 shows a schematic block diagram representation of a section of the device shown in FIG. 16. The server 110 provides digital content (not shown) and can be connected to the protected function block 120 , for example, via a wide-area data network (WAN) 210 via a modem 212 . In this case, the function block 120 is connected to a playback device and has a browser / player 1500 which can also be designed as a plug-in to an existing browser and which, in addition to the decrypted data, is also able to provide status information about units used, times or to represent prices or remaining credit. Instead of a modem, another suitable network functionality device, for example for ISDN, GSM or UMTS, can also be used. Certain details of FIG. 16, in particular consumption measurement 130, limiter 134 and value memory 140 are not shown in Fig. 17.

In Fig. 17, a card module 215 is provided which can optionally be used as rights and control chart for the control of the decoder 122, which is preferably designed as a smart card.

Fig. 18 shows a schematic representation of a first exemplary system architecture of an apparatus for distributing, billing and payment of digital media content.

A use device for the use of digital content by the consumer is designated by reference number 310 . The usage device 310 can be provided with a coupling device for coupling a card module 315 .

A media server 320 holds content files 330 , which each contain digital content and pricing information. The media server 320 can be connected to the use device 310, in particular for downloading content files 330 , via a data network connection 340 , preferably via the Internet.

Individual providers of digital content can operate supply servers 350 A, 350 B, 350 C, each of which is connected to the media server 320 via a data network connection 352 A, 352 B, 325 C, for example via the Internet.

In the arrangement shown in FIG. 18, it is up to the providers 350 A, 350 B, 350 C, files 354 A, 354 B, 354 C with digital content and pricing information 356 A, 356 B, 356 C. If a certain digital content is requested by the consumer (not shown) by means of the use device 310 , the content provider 350 A, 350 B, 350 C assigns the corresponding content file 354 A, 354 B, 354 C certain tariff information 356 A, 356 B, 356 C and transfers the content files 354 A, 354 B, 354 C to the media server 320 , from where they can be transferred to the use device 310 for use by the consumer.

Fig. 19 shows a schematic representation of a second exemplary system architecture of an apparatus for distributing, billing and payment of digital media content.

In the variant of the arrangement from FIG. 18 shown in FIG. 19, predetermined tariff categories 322 A, 322 B, 322 C, 322 D are set up on the media server 320 , and the providers of content files 354 A, 354 B, 354 C determine the valid tariffing model for each of the content files by the data transfer 352 A, 352 B, 352 C, 352 D in a file-specific area 322 A, 322 B, 322 C, 322 D of the media server according to tariff categories 320 is done.

FIG. 20 shows a first diagram for discussing the dependence of the volume received by the consumer on the side of a page-oriented text document (not shown) on the vertical axis on the usage time on the use of this page on the horizontal axis. The scaling of the vertical axis is to be understood in such a way that a page of text read several times also counts accordingly several times. The number of pages of the text work assumed in the example shown is 120 pages.

Assuming a constant reading speed results for one exemplary slow reader, for example the reading curve labeled C. low slope, with each of the 120 pages after about 15 hours of reading of the work has been read by the consumer.

Accordingly, for an exemplary fast reader, for example the reading curve marked B steeply, at which after about 4 Hours of reading each of the 120 pages of the work once by the consumer has been read.

Finally, for an exemplary medium-fast reader, this results for example, the reading curve marked with a low slope, with the after about 7.5 hours of reading each of the 120 pages of the work once from Has been read by consumers.

Based on the reading curve A, the tariff is chosen such that the route from the zero point to the point at which after about 15 hours about 240 Pages have been read by the consumer, a fee of DM 6.00 assigned. Reading the work once therefore costs DM 3.00 in approx. 7.5 Hours. Fractions or multiples thereof are proportionally proportional settled.

Fig. 21 shows a curve chart for discussion of the dependence between the intensity of use of a work and associated price. While in the diagram shown in FIG. 20 the fee increases in proportion to the number of pages read, in FIG. 21 alternative, non-linear tariff curves are shown.

In the example shown, "sensual works" such as texts by beautiful intellectual literature of "functional works" such as textbooks distinguished.

For sensual works, it can be desirable from a marketing point of view be, the use of digital content using an appropriate technical To classify infrastructure in such a way that the first quantitative shares of Work use billed by the consumer with a lower fee so that it can be expected without worrying about high Can orientate usage fees and arouse interest with them Continue consumption.

Accordingly, it can be desirable for functional works, the use digital content using an appropriate technical infrastructure rate that the first quantitative proportions of the work use compared to the Use of parts of the work located further back by the consumer with one higher charges are billed, since those from the beginning information extracted from the work is often subjectively the largest Show utility value.

Fig. 22 is a first diagram for discussion of the dependence is received by the consumer of the volume of a page of a text document of the type used on the use of this page usage time.

The time that the consumer spends on the is plotted on the horizontal axis Reading a single page of a text-oriented work used. On the vertical axis is the percentage that the consumer already has amount of text read is shown in relation to the total amount of text on the page.

The reading curve entered in the diagram shown takes into account one certain orientation time t1 of 15 seconds by way of example, d. H. for all Points in time between 0 and 15 seconds are assumed that the reader has not yet taken a substantial amount of reading material.

At an exemplary point in time t1 + t2, in the example after 2 Minutes and 53 seconds, the reader has about 75% of the amount of text viewed text page read. After a total time t1 + t2 + t3 of 3 minutes and the page is fully read within 45 seconds.

The invention enables, for example, tariffing in particular, in which a page-oriented text work is billed according to volume, whereby a single page shown on a display does not immediately after its Visibility becomes fully charged. Rather, the site is viewed during the Orientation time [0, t1] viewed as unused with regard to tariffing and not calculated at all. Only after a predetermined time t1 + t2 + t3 applies the page as fully used by the consumer in terms of tariffs.

FIG. 23 schematically shows, by way of example, time sequences when the consumer uses a page of a page-oriented text work with a tariffing methodology shown in FIG. 22.

The rectangles symbolize one and the same page of a page-oriented text work; here a page with the page number 21. After the page has been displayed on a display device, the page is not used within the orientation time of, for example, 15 seconds ( FIG. 23A). After the orientation time has elapsed, the page usage price of, for example, DM 0.025 is fully calculated ( FIG. 23B), even if the user has only received a fraction of the text content of the page. The period of time during which this page is shown on the display is continuously recorded ( FIG. 23C). Assume that the reader ends the display of the relevant page after 15 seconds from the start of the paid use of the page after the orientation time by turning to another page (in the example to page 36), canceling the use of the respective work or even switching off the display device ( Fig. 23D), the usage time previously stored for this page is cached. A free orientation time of 15 seconds is again granted for orientation on the new page 36. If the consumer then displays the same page 21 again at a later time ( FIG. 23E), a new orientation time is initially granted. After the new orientation time has elapsed ( FIG. 23F), the time calculation is continued, taking into account the time already spent by the consumer in the past when viewing this page. When the predetermined time for single use of the page has expired, the page is considered to be fully read ( Fig. 23G). There is no further time-dependent fee calculation as long as the page is continuously shown on the display ( Fig. 23H). Instead of a single storage of started usage times for special pages, a time credit account can also be kept in a simplified manner, in which unused times are accumulated from all pages left prematurely and made available to the user for viewing the same or completely new additional pages.

Fig. 24 is a second diagram for discussion of the dependency is received by the consumer of the volume of a page of a text document of the type used on the use of this page usage time.

The reading curve shown in FIG. 24 corresponds to the reading state of the page shown in FIG. 23C.

Fig. 25 is a third diagram for discussion of the dependency is received by the consumer of the volume of a page of a text document of the type used on the use of this page usage time.

The reading curve shown in FIG. 25 corresponds to the reading state of the page shown in FIG. 23H.

Fig. 26 shows a schematic representation of the reading process with the acquisition of status rights.

The tariffing options made possible by the invention include, in particular, tariffing models in which status rights can be acquired from a page-oriented text work at plant level and / or at page level and can be mapped in a suitable manner using information technology. For example, the complex volume / time billing mode shown in FIGS. 20 to 25 enables the consumer to be credited with residual portions of the page-related reading time. This is symbolically indicated in FIG. 26 by the fact that the time portions consumed per page are shown hatched, whereas the remaining time portions are not hatched. In addition, provider-side rules can be specified that describe the transition from a volume-based settlement, a time-oriented settlement or a complex volume / time settlement to a purchase-oriented settlement.

For example, it can be predetermined for a certain work (identified by a work identification number 2349457 in FIG. 26) that after two readings the reader acquires an unlimited right of use without any additional fee.

In Fig. 26 further possible classification rules are given purely symbolically, for example that a degressive tariff is used or that the content may not be used after it has been read twice.

Fig. 27 shows a schematic representation of an inventive device with a card.

Reference numerals 1202 and 1204 each denote a first device for use and usage billing of digital content or a second device for use and usage billing. The distribution server 110 is connected via the data traffic network (WAN) 210 to the devices 1202 and 1204 for downloading files held on the server with digital content intended for use by the consumer (not shown). It goes without saying that these files can also be transmitted to the consumer by means of devices 1202 or 1204 by exchanging physical data carriers (for example CDs, CD-ROM, DVD etc.).

The devices 1202 and 1204 each have a receiving device 1206 or 1208 for a card module 1210 . Each of the devices 1202 and 1204 also has a structure corresponding to the details shown in FIGS. 16 and 17, ie in particular a decoder 1212 or 1214 is provided. The other components required for billing, such as consumption measurement, limiter, credit memory and consumption history, are not shown.

On the one hand, FIG. 27 shows that the consumer (not shown) uses a work with a work identification 333 by means of the device 1202 and has used the work volume to a total of 420%, that is to say over 4 times.

The privileges acquired by repeatedly playing the work 333 are stored on the card module 1210 . If the user changes to another device 1204 (in the right half in FIG. 27) and requests there again the work which is not present on the device 1204 , so that this must be made available again by the server 110 via the WAN 210 , this becomes so coded for decoder B in different forms. The privileges acquired are nevertheless effective when the card module 1210 is inserted into the device 1204 , so that depending on the pricing model, for example degressively, the replay of the work 333 is cumulatively viewed, for example, in the end at 600% and calculated accordingly. The example in FIG. 27 shows that one and the same work can be provided with different encryption in different devices and can nevertheless be called up by means of the same card module 1210 .

Fig. 28 shows a schematic representation of a rights management and transfer means of a card module. FIG. 28 shows that one and the same card module 1210 is able to retrieve digital media content from one or more servers on different playback devices in different formats. The card module 1210 is shown in the left part in connection with an MP3 player to play sound signals or music, in the middle part is inserted into a set-top box B or a television set or another terminal connected to this in order to display video signals and in right part in connection with an e-book reader for displaying text and / or picture pages.

Fig. 29 is a schematic illustration showing another rights management and transfer means of a card module. In particular, module-based encryption is shown here, which makes it possible to make calls online and to transfer data and consume it offline. The user requests a work from a multimedia content provider CPr1 via a telecommunication module equipped with a rights card (e.g. GSM or UMTS) via his telecommunication service. The rights card is additionally provided with an encryption module, the key type of which is known to the telecommunications service. The multimedia content provider CPr1, as a synergy partner of the telecommunications service, uses the telephone number of the end user to ask the telecommunications service which key is to be used for this telephone number and sends its work with the appropriate encryption directly to the end user. He can only consume the work using his rights card with the appropriate individual decryption module either in life streaming mode or offline in viewing mode. Billing takes place via the telecommunications service.

A device for the use and usage billing of digital content is designated by reference number 1410 . A technical IT infrastructure of a telecommunications provider is identified by reference number 1415 . Technical IT infrastructures from content providers for files with digital (multimedia) content are identified by the reference numerals 1420 A, 1420 B, 1420 C and 1420 D.

FIG. 30 shows a flowchart of a download process in connection with FIG. 31 shows different possible solutions for the implementation of the invention. In the simplest and most insecure case, the entire encryption of the media files and the user and tariff data is implemented using a software solution on a conventional PC. To increase security, the latter can also communicate with a token solution, for example a chip card. The highest security is given with an integrated and encapsulated end device (appliance solution, e.g. MP3 player), in which opening leads to data loss.

Universal mobile device

FIG. 32 shows an advantageous digital mobile device in a particular embodiment as a wearable computer 127010, in particular as a multimedia player preferably including digital rights management system (DRMS) is used. The mobile device 127010 can have a PCMCIA slot 127020 , which can be used in particular to hold a smart card chip card, for example for distribution and payment systems.

The PCMCIA interface can thus also be used for other functionalities or extensions, for example for adapter cards for smart media modules or similar memory cards, processor cards or other software and / or hardware extensions. It is then also possible to equip the 127010 mobile device with a mobile phone functionality, for example WAP, SMS, GSM, GAPS, UMTS.

One embodiment is the design of a PCMCIA card as a decoder module for digital rights management with integrated memory, smart card reader and / or means for telephony or for data communication / transmission via WAN (GSM, UMTS, GPRS etc.).

Alternatively, operation with an input pen (not shown) can also be provided. In a further development, the microphone / earphone set 127050 has a switching device 127060 with which, for example, music playback can be switched off and an incoming telephone call can be switched on. After the phone call has ended, the music playback can be switched on again by pressing the button again.

The display and control unit 127030 can be equipped with its own processor or control device and its own accumulator (battery). With this variant, the playback software ("Player") can therefore run directly on the display and control unit 127030 . This makes it possible in particular to first copy-protected data formats in the display and control unit 127030 and to feed them to the listener. The data stream between mobile device 127010 and display and control unit 127030 can be encrypted , for example, using the SSL protocol. With such a configuration, the factory decoder (not shown) can be provided with the digital rights management system in the mobile device 127010 without there being a risk of unauthorized copying. In this embodiment, for example, content can be streamed from the wearable computer to a player or a browser set up for this purpose in the display and control unit, as long as the requirements for this are met, for example by a coupled rights smart card in the wearable part or in the display and control panel.

A special design of the display and control unit is the possibility of Representation of the operating function of the device to be controlled and the possibility the display of multimedia content that is currently being played related information such as title, credit, playing time etc. or lists playable or orderable multimedia works. With multifunctional Design of the display and control unit, for example, both as a media Player as well as a mobile phone can switch between displaying z. B. Telephone numbers and the display of currently played tracks or the available standing or orderable titles automatically, depending on the operating mode or on Input back and forth. If you are on the phone, you can Participants are displayed or even depicted, a z. B. Pieces of music played (suppressed when calling) are corresponding Information shown on the display.

The mobile device 127010 can work with other devices such as e-book readers, PDAs, web tablets, PCs or projectors in the same or similar form via LAN data coupling, if provided for this purpose. The mobile device can also interact with the Internet via a WAN link other than wireless via GSM, GPRS, UMTS etc., such as via an analog telephone line, an ISDN line or DSL.

Accumulators (not shown) are advantageously arranged in the lower region of the housing for reasons of load.

An embodiment is particularly advantageous in which the housing can rotate somewhat relative to the belt by means of a coupling part (not shown), so that it can always align itself in the direction of gravity. Conventional peripheral devices, such as printers etc., can be connected to the mobile device 127010 in a further developed embodiment.

Fig. 33 shows the display and control unit 127040 in FIG. 32. In a particularly preferred further development, the display and control unit 127040 in the upper and lower end face of a 128010, 128010 b each have a plug-in and locking means (not shown), by means of which a cover module 128020 can be pushed onto the display and control unit 127040 , locked and, if necessary, also electrically connected. In a special embodiment, the cover module 128020 is equipped with a telephone keypad, has a viewing window for displaying the display and control unit 127040 and, if the microphone is not included in the display and control unit 127040 , can have an ear cup and speech microphone (not shown) ,

• a) dass der Benutzer telefonieren kann, wie er es vom herkömmlichen Mobiltelefon her gewohnt ist, und
• b) dass ein ursprünglich als Abspielgerät konfiguriertes Gerät gegebenenfalls nachträglich auf einfache Weise zu einem Mobiltelefon aufgerüstet werden kann oder umgekehrt.

The lid module 128020 can be designed in a wide and fashionable range of shapes and colors. The purpose is

• a) that the user can make calls as he is used to from a conventional mobile phone, and
• b) that a device originally configured as a playback device can be subsequently upgraded to a mobile phone in a simple manner, or vice versa.

The lid module 128020 can be plugged onto the display and control unit 127040 at the top or bottom, depending on the left or right handedness of the user. The orientation of the display on the display and control unit 127040 is automatically aligned accordingly, so that texts and images can always be read. In a simplified embodiment, this feature can also be omitted. Another advantageous design option for the display and control unit is the lateral design of input or control elements on the edge of the display, which faces away from the display, with which the display and control unit 127040 can be held and operated with one hand. A special embodiment is the implementation of the input option by means of at least three input buttons, which enables certain basic functions, such as scrolling, scrolling and triggering marked functions or menus. The location and number of plug-in and snap-in connections (if available) as well as the input options can vary in individual cases.

The plug-in connection is particularly advantageous due to the possibility of coupling with a holder, such as in vehicles (not shown), the operation and the sound input and output taking place via the same interface as that of the cover module. The advantage of the separate display and control unit 127040 lies in particular in the compact and very easy to implement design.

In mobile applications, the GSM or UMTS transmission antenna can be attached to the mobile device 127010 , which may even be away from the body, e.g. B. can be stored on a table, away from particularly sensitive body parts such as the head.
