Milsted Qing Gong BACKGROUND OF THE INVENTION The present invention disclosed in the technical field relates to e-commerce in a broad sense ( electronic commerce), especially the right to securely transfer and manage digital assets such as print media, movies, video games, and music via global communication networks such as the Internet and the World Wide Web System and related tools. Prior art The trend of using global distribution systems such as the Internet to deliver music, movies, computer programs, pictures, video games, and other content continues to grow. At the same time, owners and publishers of valuable digital content have reduced or slowed their acceptance of the use of the Internet to distribute digital assets for several reasons. The first reason is that everyone fears unauthorized copying or plagiarism of digital content. The electronic delivery of digital content removes several obstacles to plagiarism. One obstacle removed by electronic distribution is the need for physical recordable media (such as floppy disks or optical disks) themselves. While copying digital content to physical media ’is accomplished in many situations using blank audio cassettes or recordable discs.

O: \ 85 \ 85156 Divide .DOC 200304126, Ben: It ’s, but it always costs money. However, in the electronic distribution 2 material form, it is no longer necessary for physical media 1 to distribute content in a heart-like manner, so the cost of physical media is not a factor. The second obstacle is the format of 2 Valley itself ', that is, content stored in m format versus content stored in -digital format. When copying content stored in an analog format such as a printed picture temple by photocopying, the quality of the copy is lower than the original quality of the mouth. The quality of each subsequent copy (sometimes called _generation) is lower than the original quality. When pictures are stored digitally, no degradation occurs. Every copy and every copy is as clear and sharp as the original picture. Due to the perfect integration of digital copies and the integrated effect of using electronic means to distribute content at low cost and to distribute content extensively via the Internet, the theft and distribution of unauthorized copies is made possible by Gu Yi . Just by pressing a few keys on the keyboard, illegal copyers can send hundreds or even thousands of perfectly copied digital content via the Internet. So ‘it ’s time to ensure the protection and security of digital assets that are delivered electronically. Digital content providers want a secure, digital content global distribution system that protects the rights of content owners. Issues in setting up a digital content distribution system include developing systems for digital content electronic distribution, rights management, and Beijinbao 4 <system. Digital content distributed electronically includes content such as print media, bones, movies, video games, programs, television, multimedia, and music. When an electronic distribution system is deployed, digital content providers can quickly get paid through immediate sales returns and electronic reconciliation, and internally

O: \ 85 \ 85156 Divide the reissue of .DOC 200304126 and get a second source of revenue. Because the electronic digital content distribution system is not affected by physical inventory shortages or returns, digital content providers and retailers can have lower costs and higher profit margins. Digital content providers can assist new distribution channels or strengthen existing distribution channels to distribute inventory faster. The parent-friendly data of the electronic distribution system can be used to obtain information related to customer purchase patterns and used to provide immediate feedback related to pen-based marketing plans and promotions. To achieve these goals, digital content providers need to use an electronic distribution model to enable a wide range of users and businesses to access digital content, while ensuring the protection and billing of digital assets. Such as real audio, AT &amp; T's A2B, Liquid

Digital content available on the market, such as Music Network and other systems, electronic content distribution systems provide digital data transmission via secured and unsecured &lt; electronic networks. When using a secured electronic network, the requirements for digital content providers to distribute digital data to a wide range of audiences are greatly reduced. When using unsecured networks such as the Internet and the World Wide Web, digital content can be securely delivered to users using encryption. However, once the encrypted digital content is decrypted on the user's machine, the user is liable to unauthorized re-distribution of the digital content. Therefore, a secure digital content electronic distribution system is currently required. The Shaw system provides protection for digital assets and ensures that even after delivering digital content to consumers and businesses, it can protect content providers ^ τ Shoulder J Conical. Therefore, rights management needs to be able to control the secure distribution, contract authorization, other * owed, and only the use of digital assets 〇. \ 85 \ 85156 division -10- 200304126. Another reason that digital content owners have slowed their acceptance of electronic distribution is that these digital content owners want to maintain and promote existing distribution channels. Most content owners sell through retailers. In the music market, these US retailers include Tower Rectors, peaches, Blockbuster, Circuit City, and others. Many of these retailers have websites 'that allow Internet users to purchase via the Internet' and can email users to purchase them. Music sites include @tower, Music Boulevard, and Columbia House. When using electronic distribution, these retail stores may not be differentiated from each other, and they may not be differentiated from the insider owner, especially on the World Wide Web. Therefore, there is currently a need for electronic content retailers such as pictures, video games, music, programs, and video products to sell them through electronic distribution. The way. Each owner prepares their digital content for electronic distribution via distribution sites such as electronic stores. Electronic stores on the Internet or electronic stores through other online services want to differentiate each other through their product lines and PP promotions. Traditional stores (that is, non-electronic and non-online stores analogous to electronic stores) use product promotions, product salespeople, product samples, free returns policies, and other promotional programs to differentiate them from competitors . However, in the online world where content providers have conditions for using digital content, the ability of electronic stores to differentiate can be severely limited. In addition, even though the conditions of use can be changed,

O: \ 85 \ 85156 segmentation. DOC -11-200304126 Both stores also face difficulties in processing digital content associated with content from content providers 丨 /, metadata in order to promote and sell products electronically ^ There are several needs that need to be managed when working as an electronic store for intermediary data. $ Sub-store to receive digital media-related information from content providers. Most of the time it may be that part of this intermediary is transmitted encrypted, so content providers must establish a mechanism to decrypt encrypted content. Second, electronic stores may want to preview content from content providers before they receive content from content providers, or after receiving content from electronic stores, in order to facilitate product marketing, product: bits, and other content-related promotions. Think about it. Third, electronic stores: I want to grab some of the promotional materials used in promotional materials such as graphics and artists. Sub-stores usually use such promotional materials directly for online sales. Fourth, e-shops may wish to modify certain permissible conditions of use in order to produce different digital content products and lines that differentiate them from other e-shops. Fifth, e-shops may need to insert certain addresses, such as web addresses, into intermediary materials, or change some addresses in intermediary materials, so that buyers can automatically pay a billing agency instead of paying to the e-shop π person, /, Baozi store may need to generate a license to allow the use of copyrighted digital content in accordance with the conditions of use. For example, the license may permit a limited number of copies of the digital content. The license must reflect the terms agreed. In view of all of these requirements, in order to process intermediary materials related to digital content, many electronic stores write custom specifications software programs to handle these requests. The time required to develop these custom-spec software programs is divided into O: \ 85 \ 85156. Doc -12- 200304126 This is quite a lot. Therefore, a solution to this requirement is currently needed. σHuai Nei Valley owners have slowed down another reason for accepting electronic distribution: The difficulty of preparing content for electronic distribution. Many content providers currently have thousands or even tens of thousands of product content in their product catalogs. In an example of a music flat, it is not too surprising that the content owner has several different t-styles (e.g., CD, audio cassette, and MD) on the single-recording master tape at the same time. This form may be directed to a specific distribution channel, or to a specific distribution medium such as D record, τ, D VD, or equivalent media. The record θ master V is remastered or remixed. The mix for radio stations may be different from the mix for dance music notes, or it may be different from the mix for CDs available to the average consumer. Inventorying and chasing these different mix versions can be quite cumbersome. In addition, many recording masters often reissue old recordings in a variety of subsequent publishing series, such as "Selected Works," or arrange them into movie soundtracks and other publishing series, "Reproduction," or other arrangements. When As more content is provided digitally, the content is remixed or reprocessed and coded, and the need for electronic distribution has grown. Content owners often need to use the old recording format as a guide in order to choose the right recording master And re-process and encode each recording, and then distribute it through electronic distribution. Content providers who want to use their old format to assist them in re-issuing old recordings to power sub-distribution are particularly suitable ㈣. $ 容 Provider will search the database to match the content name, artist, and recording, set the encoding parameters, and retrieve the associated content information or attached materials, such as 0 __ \ 85 \ 85156 split. DOC -13 -200304126: China has included wooden #, website address, Qiaowen record, and relevant promotional information for sample audition section temple. This kind of manual method The process of searching the database is not without its shortcomings. One disadvantage is the need for = personnel to manually search the -database and set the processing parameters appropriately. Another disadvantage is that the operator may choose the resources from a database. Probability of a stomach error. Therefore, currently there is a need to automatically expand the relevant information and recording master tapes of internal customers such as Yue Xun. Content owners prepare and power sub-types through a program called coding Digital content delivered. Encoding involves obtaining the content, digitizing the content when presented in an analog format, and compressing the content. The compression program makes digital content more efficient It is transmitted via 在 and stored in recordable media. This is because the amount of resources transmitted or stored is reduced! However, compression is not without its disadvantages. Most compressions involve the loss of certain information, so they are called lossy. Compression (1〇ssy c〇mpressiGn). The content provider must decide to use 胄 = compression level. For example, in music, digital content or song = video Different wood types have quite different characteristics. For a certain type, the compression algorithm and compression level chosen may not be the best choice for another music type. Content providers may find that certain combinations of compression algorithms are equivalent It is suitable for a certain type of music such as classical music: for other types of music such as heavy metal music, it is impossible to get a full spoonful of results. In addition, 'recording engineers often have to adjust the music slightly, etc.' to perform dynamic range adjustment And perform other pre-processing and processing settings to ensure that the type of music encoded will produce the desired result. This O: \ 85 \ S5156 segmentation_D〇c -14- 200304126 must be set manually The need for encoding parameters, such as setting equalization levels for each digital content and the need for dynamic compression and expansion settings, can be cumbersome and costly. Going back to the music example, a music content provider with a content series covering multiple genres of music will have to manually select each song or group of songs to be encoded, and the required combination of encoding parameters. Therefore, there is currently a need for a method that does not require manual selection of encoding processing parameters. Programs that compress content may require a significant amount of dedicated computing resources, especially for larger content projects such as full-length movies. Compression algorithm vendors offer various advantages and disadvantages associated with money shrinking technology. These trade-offs include: the length of time and computing resources required to compress the content; the £,, and bit rate required for playback in the original content obtained from the original content; the performance of the compressed content; and other factors. When an encoding program uses -multimedia files as input 'and generates an encoded output building, but there is no process or state, the transition period refers to 7T: when' this problem occurs when using this encoding program. In addition, in the eve of ^^^ / ', another program is used to call or manage a coding program that has no process transition instruction. This will make the calling application unable to measure the amount of coded content as a percentage of the complete selection specified to be coded. When the calling program is attempting to schedule the execution of several different programs for immediate execution, the problem described above will occur. In addition, the situation described above is quite cumbersome when you have selected the endorsement / person to be coded and the endogenous provider wants to determine the progress of the encoding process. Therefore, a way is needed to solve this problem. — Digital content providers have slowed down another reason to adopt electronic distribution

O: \ 85 \ 85156 Split. DOC -15- 200304126 is: its content lacks the standard for digital players to produce digital players on electronic devices. Content providers, e-shops, or other members of the electronic distribution chain may want to provide customized playback on a variety of devices such as personal computer systems, set-top boxes, and handheld devices machine. There is a need for a set of tools that can decrypt digital content in a tamper-resistant environment (that is, an environment that prevents unauthorized access to the content while a third party is playing). In addition, a set of utility programs is required to enable a user to manage a local digital content library, but the set of utility programs does not allow the user to access content that is not purchased for use.

System overview Secure digital content An electronic distribution system is a technology platform that includes the technologies, specifications, tools, programs, and programs needed to securely transfer digital content and content related to digital content to a user client device and manage rights on those content. And software. User devices include personal computer systems, video converters (IRDs), and Internet devices. These devices may copy the content to external media or portable, portable, or smart home appliances with the permission of the content owner. The term Digital Content (CQn) or Content (CQn): Information and data stored in reading format, including: pictures, movies, video programs, music, programs, multimedia, and video games. 11 The technology platform specifies how to prepare digital content How to use point-to-point or κ-broadcast infrastructure (such as I-line, Internet, satellite, and radio) and 〇: \ 85 \ 85! 56 to divide D〇c -22- 200304126, Wang also delivers, how to authorize Device, and how to prevent unskilled copying or playback. In addition, the technology platform's architecture allows for advancements in various technologies such as watermarking, compression / encoding, encryption, and other security algorithms to progress over time. Integrate or transplant these technologies. The basic components of a secure digital content electronic distribution system include: (1) rights management for the owner's ownership protection; (2) transaction counting for immediate and accurate Remuneration payments; and an open and well-documented framework that allows content providers to prepare content and allow it to be built across multiple network infrastructures It is designed to be securely distributed for playback on any standard-compliant player. 1. Rights management implements the rights in the secure digital content electronic distribution system through a set of functions distributed between the various working components of the system. Its key functions include: · Licensing and control, so that the content can only be decoded by authorized intermediaries or end users who have obtained an authorized license; and according to the terms of the purchase or license, such as copying allowed Number of times, number of playbacks, or the time interval or period during which the license is valid, to control and enforce the use of the content. A secondary function of rights management is to activate a device to identify the origin of unauthorized content copies so that Combating plagiarism. It uses a Clearing House entity and Secure Container (sc) technology to implement authorization and control. The clearing house has verified that the transaction has been successfully completed—after authorizing the transaction, even if an intermediary or End-users can decode content to provide licenses O: \ 85 \ 85156 points .D0C -23- 200304126 Yes. A secure container object is used to distribute encrypted content and information between system components. Sc is an encrypted information or content carrier that uses encryption, digital signatures, and digital certificates , So that electronic information and content will not be intercepted or modified without authorization. The sc can also verify the trustworthiness and integrity of digital content. The advantages of these rights management functions are: Electronic digital content distribution infrastructure is not necessarily If it is secure or trusted. Therefore, it can be transmitted via network infrastructure such as the World Wide Web and the Internet. This is because the content is encrypted in a secure container object, and the content is stored and distributed Isolated from the decryption and use of the content. Only users with a decryption key can decrypt the encrypted content, and the clearing house only issues decryption keys for authorized and appropriate use requests. Qingyi will not approve additional requirements from unknown or unauthorized persons, or requirements that do not meet the content use conditions set by the content owner. In addition, if an SC is altered during the transmission of the content, the software in the clearing house decides that the sc is altered or forged, and refuses to accept the transaction. Control of the use of content is initiated by an end-user playback application (i95) running on an end-user device. The application embeds a digital code into each piece of content, which specifies the allowable number of copies and playbacks. The digital watermarking technology is used to generate the digital code, so that other end-user playback applications (195) cannot know the digital code, and make the digital resistant to change. In an alternative embodiment, the digital code is only saved as part of the conditions of use associated with the content (113). When the digital content (113) is accessed in a standard end-user device, the end-user playback application (195) reads the watermark in order to detect

O: \ 85 \ 85156 Divide .d〇C -24- 200304126 Check the usage restrictions and update the watermark when needed. If the required use of the content does not meet the usage conditions, such as running out of copies, the end-user device will not execute the request. Digital watermarks also provide a way to identify the source of authorized or unauthorized content copies. The content owner embeds an initial watermark into the content in order to identify the content owner, specify copyright information, specify distribution geographic areas, and add other relevant information. A second watermark is embedded in the content on the end-user device to identify the content purchaser (or license) and end-user device, specify the purchase or license conditions and dates, and add any other relevant information. Because watermarks become an integral part of the content, whether the copy is authorized or unauthorized, the content must contain these watermarks. Therefore, wherever the content is stored, and regardless of the source of the content ', digital content necessarily contains information about the source of the content and its permitted use. This information can be used to combat illegal use of the content. 2. Measurement The clearing house maintains a record of all transactions approved for key exchange via that clearing house 'as part of its rights management function. This record measures licenses and original conditions of use. The transaction record may be reported to various responsible parties, such as content owners or content providers, retailers, and other relevant partners, in an immediate or regular manner to facilitate the reconciliation of transaction payments electronically, and Other uses. 3. Open architecture The secure digital content electronic distribution system is an open architecture.

O: \ 85 \ 85156 Segmentation. DOC -25- 200304126 The architecture has published specifications and interfaces, which helps to implement and accept the system in a wide range of markets, while maintaining the protection of the rights of content owners. The flexibility and openness of the system architecture also enables the system to progress over time when various technologies, transmission infrastructure, and devices enter the market. The architecture is open in terms of the nature of the content and its format. The architecture supports the distribution of audio, programming, multimedia, video, or other types of content. Each frame can be a native format such as linear for digital music, or a format obtained by additional pre-processing or encoding such as filtering, compression, or pre-emphasis / de-emphasis. The architecture is open to various encryption and watermarking technologies. The architecture can select specific technologies to suit different content types and formats, and can import or adopt newly developed technologies. This flexibility allows content providers to select and upgrade their technologies for data compression, encryption, and formatting within secure digital content electronic distribution systems. The child architecture is also open to different distribution networks and distribution models. The architecture supports content distribution over low-speed Internet connections or high-speed satellite and cable networks, and can work with peer-to-peer or broadcast models. In addition, the architecture is designed to implement the functions in end-user devices on a variety of devices including low-cost consumer appliances. This device allows content providers and retailers to provide content to middlemen or end users through a variety of service types, and allows users to purchase content or obtain a license for the content. This content is recorded in various standards-compliant playbacks. 0-2003-04126 B. System function components. Please refer to FIG. 1.

The following sections provide a high-level description of these business components and system components related to electronic content 113 distribution. 1. Content Provider 101 The content provider 101 or the content owner is the owner of the original content 113 and / or a distributor authorized to make the independent content 113 into a package for further distribution. The content provider 101 can directly use its rights, or authorize the content 113 to the electronic digital content store 103, or a middle market partner (not shown in the figure), and usually recover the content usage payment related to the e-commerce revenue. Examples of internal talent gift providers 101 include Sony, Time_Warner, MTV, IBM, MiCrOS0ft, Turner, Fox, and other content providers. Each of the providers 101 uses tools provided as part of the secure digital content electronic distribution system 100 to prepare its content 113 and related shellfish for distribution. A workflow management program i 5 4 schedules the content 113 to be processed, and tracks the content 113 as it passes through the steps of content 113 preparation and package composition, in order to maintain excellent quality O: \ S5 \ 85156 Segmentation.

Password concept and its application on secure digital content electronic distribution system Authorization control in secure digital content electronic distribution system 100 is based on password usage. This section describes the basic cryptographic techniques of the present invention. Public key encryption, symmetric key encryption, digital signatures, digital watermarks, and digital certificates are all known. A_Symmetric Algorithm In the secure digital content electronic distribution system 100, the content provider 101 encrypts the content using a symmetric algorithm. Because this algorithm uses the same key to encrypt and decrypt data, it is called a symmetric algorithm. The sender and recipient of the message must share the key. The shared key is called symmetric key in this paper. The secure digital content electronic distribution system 100 has nothing to do with the special hard symmetric algorithm selected for a particular embodiment. Common symmetric algorithms are DES, RC2, and RC4. Both DES and RC2 are block ciphers. Segment passwords encrypt data using the data bits of one segment at a time. DES is an official US government encryption standard with a 64-bit block size and uses a 56-bit key. Triple-DES is usually used to increase the security that simple DES can achieve. RSA Data Security designs RC2 ° RC2 uses a variable key length password and has a 64-bit sector length. RC4, also designed by RSA Data Security, is a variable key length bit stream cipher. Bitstream ciphers operate on a single data bit at a time. RSA data security claims that in RC4, each output byte requires eight to sixteen machine operations. O: \ 85 \ 85156 segmentation. D0C -34- 200304126 IBM designed a fast algorithm called SEAL. SEAL is a bit-streaming algorithm that uses a variable-length key and is optimized for 32-bit processors. SEAL requires about five basic machine instructions in each data byte. If the 160-bit key used is pre-processed into the internal table, a computer using a 486 CPU at 50 MHz will execute the SEAL code at a rate of 7.2 million bytes per second.

Microsoft reports the results of the Crypto Performance Standard Checker in an overview of its Crypto API document. An application using Microsoft's CryptoAPI running on a computer using a Pentium 120 MHz CPU with an operating system of Windows NT 4.0 obtained the following results. _ In the secure digital content electronic distribution system 100, the public Jinyu is used to encrypt each symmetrical Jinyu and other small data fragments. The public key algorithm uses two golden wheels. These two gold loses are mathematically related, so data encrypted with one key can be decrypted with another key. The owner of the key keeps one key secret (private key) and publicly distributes the second key (public key). To ensure the security of a confidential message using a public key algorithm, the message must be encrypted using the recipient's public key. Only recipients who have an associated secret gold coin can decrypt the message. The public O: \ 85 \ 85156 division is also used. D0C -35-200304126 Jin Yu plays a different method to generate a digital signature. Secret cuts are used for this purpose. The next section provides information related to digital signatures. The most commonly used public key algorithm is the RSA public gold cipher. RSA public key codes have become the de facto standard for public keys in the industry. Other algorithms that are also quite good for encryption and digital signatures include E1G㈣ and Rabin. RSA is a variable key length cipher. Symmetric key algorithms are much faster than public key algorithms. The speed of DES in software is approximately at least 100 times that of rsa. Therefore, rsa is not used to encrypt large amounts of data. RSA Data Security Report On a machine using a 90 MHz Pentium CPU, the RSa Data Security tool suite BSAFE 3.0 has the following generation rates in secret key operations (encryption or decryption using secret keys): It is 216 kilobits per second with a 512-bit modulus and 7.4 kilobits per second with a 1024-bit modulus. C. Digital signature In the secure digital content electronic distribution system 100, the sender of the SC (s) digitally signs the SC (s) to protect the integrity of the sc (s). In general, to generate a digital signature for a message, the owner of a message first calculates the message digest (described below), and then encrypts the message digest using the owner's secret, Jin Yu. Deliver the message with its signature. Any recipient of the message may first decrypt the signature using the public key of the owner of the message in order to recover the message digest and verify the digital signature. The recipient then calculates a digest of the received message and compares the digest to the recovered digest. If the message has not been changed during the distribution process, the calculated digest must be the same as the recovered digest. O: \ 85 \ 85156 division. DOC -36- 200304126 In the secure digital content electronic distribution system 100, because SC (s) contains several data parts, a summary is calculated for each part, and these are sequential parts A summary summary is calculated. The summary digest is encrypted using the secret key of the Sc (s) issuer. The encrypted summary digest is the SC (s) digital signature of the sender. The summary of each part and the digital signature are included in the ontology of SC (s). The recipient of sc (s) uses the received digital signature and partial digest to verify the integrity of the SC (s) and its components. A one-way hash algorithm (hash algrhhm) is used to calculate a message digest. A chaotic algorithm takes a variable-length input message and converts the input vanadium interest into a fixed-length string, that is, a message digest. The one-way clutter algorithm operates in only one direction. That is, it is easy to calculate a digest of an input message, but it is very difficult (computationally infeasible) to generate an input message from its digest. Because of the nature of the one-way mess function, we can treat a message digest as the fingerprint of the message. The one-way miscellaneous IL function we found is MD5 from rsA data security, and SHA designed by the National Institute of Technology and Standards (NITOnal Technology 0gy and Standards; NITS for short). D. Digital Certificate Digital # 明 表 is used to prove or verify the identity of the person or entity who has transmitted a digitally signed message. A certificate is a digital document issued by a certificate authority (cmificationauthty) that combines a public key with a person or entity. The child certificate includes the public key, the name of the person or entity, the expiration date, the name of the certificate authority, and other information. The certificate also contains the digital signature of the certification authority. O: \ 85 \ 85156 Division. DOC -37- 200304126 When an entity (or person) sends a message signed with its public key and accompanied by its digital certificate, the recipient of the message uses the The entity name to decide whether to accept the message. In the secure digital content electronic distribution system 100, each SC (s) other than the one issued by the end-user device 109 contains a certificate of the producer of the SC (s). Because many end users do not need to obtain a certificate or hold a certificate issued by a non-authentication certification center, the end user device 109 does not need to include the certificate in its SC (s). In the secure digital content electronic distribution system 100, the clearing house 105 may choose to issue a certificate to the electronic digital content store 103. Thus, the end-user device 109 can be independently verified that the secure digital content electronic distribution system 100 has authorized the electronic digital content store 103. E. Guide to SC (s) Graphical Representation This document uses a graphic representation to represent SC (s). The figure shows the encrypted part, non-encrypted part, encrypted Jinyu, and certificate.

The end-user device 109 requests the hosting content website to transfer the purchased content 113 corresponding to the license sc. The content 113 is transmitted to the end-user device 109. Upon receiving the O: \ 85 \ 85156 segment. D0C -47- 200304126 at 113 o'clock and winter user device 109 uses the symmetric key to decrypt the content 113. IV. Rights Management Architecture Model A. Architecture Layer Functions Figure 5 is a block diagram of the rights management architecture of the secure digital electronic distribution system and system.纟 Architecture 丨, there are four layers❹Secure digital content electronic distribution system⑽: Authorization control layer 50, content identification layer 503, content use control layer 505, and content formatting layer 507. This section describes the overall functional goals of each layer and the individual main functions of each layer. The function of each layer is completely independent of the functions of other layers. Within the broad limits, functions in one layer can be replaced by similar functions without affecting the functions of other layers. The output of one layer obviously needs to meet the acceptable format and semantics of the adjacent layers. The license control layer 501 ensures that: digital content will not be illegally intercepted and tampered with during the distribution process; content 113 comes from a legitimate content owner and passes through an authorized distributor (such as an electronic digital content store 103) And distribution; digital content purchasers have an appropriately authorized application; the month when the purchaser or end-user obtains a copy of the content; 'the purchaser pays the distributor first; and retains a transaction Record for return. The content identification layer 503 can verify the copyright and the identity of the content purchaser. The built-in copyright information and the identity of the content purchaser can track the source of any authorized or unauthorized copy of the content 113. So the content

The original notation of Shizhong is converted into a form consistent with the special service functions and distribution devices of the electronic distribution of secure digital content. This conversion process may include compression coding and its associated pre-processing, such as frequency equalization and amplitude range truncation. For audio content 3, the purchaser ′ also needs to process the received content i i 3 in order to obtain a format suitable for playback or to transmit to a portable device. B. Functional analysis and process rights management architecture model is shown in Figure 5, and the figure shows the mapping of each architectural layer to each of the working components and each layer of the friend that constitutes the secure digital content electronic distribution system 1000. Important features. 1. The content formatting layer 507 The general functions associated with the content formatting layer 507 are pre-processing of content 502 and compression 511 on the content provider 101, and content decoding 513 and decompression 515 on the end-user device 109 . Examples of pre-processed needs and special features are described above. Use content compression 5 11 to reduce the file size of content 113 and its transfer time. Suitable for any type 113 compression algorithms and transmission media can be used for secure digital content electronic distribution systems

For music, MPEG 1/2/4, Dolby AC-2 and AC-3, Sony's Adaptive Transform Coding (ATRAC), and low bit rate algorithms are some commonly used compression algorithms. law. The content 113 is stored in compressed form on the end-user device 109 in order to reduce the storage capacity requirements. Decompress the content 1 丄 3 during actual playback. It is easy to perform decoding during actual playback. The purpose and type of encoding will be explained later when the content uses the control layer 505. 2. Content use control layer 505 The content use control layer 505 allows the conditions or restrictions imposed on the use of the content 113 on the end-user device 109 to be regulated and enforced. These conditions may specify the number of times the content 113 is allowed to be played, whether subsequent copies of the content 113 are allowed, the number of subsequent copies, and whether the content can be copied to an external portable device. The content provider 丨 〇 丨 sets an allowable use condition 517, and transmits the use condition 517 in the form of an sc (see the section discussing the license control layer 501) to the electronic digital content store 103. The electronic digital content store 103 may increase or decrease the use condition 517 as long as the use condition 517 does not invalidate the original condition set by the content provider 101. The electronic digital answer store i03 then transmits (in one sc) all store usage conditions 519 to the end-user device 109 and the clearing house 105. The clearing house ⑺ $ authorizes the release of the content U3 to # 9 of the end-user device, and first executes the use condition confirmation 521. The content in the end-user device 109 is executed using the control layer 505.

Play the application private 195 and then store the content 13 in the end-user device 109, first encode the content 113 with a password. The playback application 195 generates a coded Jin Yu for each member, encrypts the key, and hides the key in the end-user device 109. Then whenever the end-user device 109 accesses the content 13 for copying or playback, the end-user device 109 verifies the Tibetan copy / playback code before allowing the content 113 to be decoded and executed for playback or copying. The end-user device 109 also appropriately updates the copy / play code in any new subsequent copies of the original copy of the content n3. Copy / play encoding is performed on the compressed content 113. That is, it is not necessary to decompress the contents 1 丨 3 before embedding the copy / play code. The end-user device 109 embeds the copy / play code in the content 13 using a license watermark 527. Only end-user playback applications 195 that can recognize the embedded algorithm and associated encoding keys can read or modify the embedded data. The viewer cannot see or hear the data; that is, the data does not cause a perceptible reduction in the quality of the content 113. Since the watermark has gone through several steps of content processing, data compression, digital-to-analog and analog-to-digital conversion, and the degradation of signal quality introduced by normal content processing, the 'watermark' is still in any representation that includes analog representations. Remains in content 113. In an alternative embodiment, an authorized license watermark 5 2 7 is not used to post the copy / play code into the content 113, and the end user plays the application 195 instead using the securely stored usage conditions 519. 3. Content identification layer 503 As part of the content identification layer 503, the content provider 10 also uses a 10: \ 85 \ 85156 segmentation. DOC -51-200304126 Authorized license watermark 527 will be used for content identification code, content owner, etc. , And other information (such as publication date and geographic distribution area), etc. are included in Content 113. This watermark is referred to as a copyright watermark 529 in the present invention. Upon receipt, 'most = user device 1G9 adds a copy of the content 113 plus the name of the content buyer and the transaction identification code 535 (see section Authorization Control = 501 below) and such dates as the authorization permission and conditions of use 5 17 and other other Λ watermarks. This watermark is referred to as a license watermark at the end of the invention. Any copy of any content that has been queried or obtained without authorization and that has been preserved in quality can be treated with copyright watermarks and license watermarks. The content identification layer 503 can deter piracy. 4. Authorization control layer 501 The authorization control layer 501 protects the content 113 from unauthorized interception and ensures that the content is only released to an end user device with appropriate authorization in an individual manner. 9 and an end user who has completed an authorized purchase transaction with an authorized digital content store 103. The authorization control layer 501 protects the content with double encryption 53. The content 113 is encrypted using an encrypted symmetric key generated by the content provider, and the symmetric key is encrypted using the public key 621 of the clearing house. Only clearing house 105 can recover the symmetric key at the beginning. The license control system designed the clearing house 105 as a "trustee." Before granting the license for license request 537 (that is, releasing the symmetric key 623 of content 113 to the end-user device 109), the clearing house 105 Validation first.

In Figure 6, it is also assumed that the digital digital content store 103 has downloaded the end-user playback application 195 to an end-user in accordance with the standard World Wide Web communication protocol. Device 109. This architecture requires an electronic digital content store to assign a unique application identification code to the downloaded playback application 195 'and requires the end-user device 1 () 9 to store the identification code for subsequent application authorization License verification (see below). The overall licensing process begins with content provider 101. The content provider 101 encrypts the content 113 with a locally generated encryption symmetric key, and encrypts the symmetric key 623 with the public key 621 of the clearing house 105. In an alternative embodiment, instead of generating the symmetric key locally, the symmetric key is transmitted from the clearing house 105 to the content provider. The content provider produces a content Sc (s) 63 surrounding the encrypted content 113, a symmetric key 623 surrounding the encryption, SC (s) 620, store usage conditions 5 19, and associated information Other content 丨 13. Each content 113 object has an intermediary data SC (s) 620 and a content sc (s) 630. The content 113 object can be a compression level of the same song, or the content n 3 object can be each song on the album, or the content n 3 object can be the entire album. For each content 113 object, the intermediary data sc (s) 620 also contains the store use conditions 5 1 9 associated with the content use control layer 505. In step 601, the content provider 101 distributes the intermediary material sc (s) 620 to one or more electronic digital content stores 103, and distributes the content SC (s) 630 to one or more in step 602. Multiple hosted content sites. Each electronic number O: \ 85 \ 85156 is divided. DOC -54- 200304126 The content store 103 generates another quote SC (s) 641. The quotation SC (s) 641 usually contains much of the same information as the intermediary material SC (s) 620, including the digital signature 624 of the content provider 101 and the digital certificate of the content provider 101 (not shown in the figure). As mentioned above, the electronic digital content store 103 can increase or decrease the store usage conditions 519 specified by the content provider 1010 at the beginning (processed by the content use control layer). You can also choose to sign the content SC (s) 630 and / or the intermediary data SC (s) 620 with the digital signature of the content provider 101. The end-user device 10 and 9 were completed in step 603. After the content purchase transaction between the electronic digital content stores 103, the electronic digital content store 103 generates a transaction SC (s) 640 in step 604 and transmits the transaction SC (s) 640 to the end-user device 109. The transaction SC (s) 640 includes a unique parent easy identification code 53 5. The name of the purchaser (ie, the end user) (not shown in the figure), the public key 66 of the end user device i 09, and A quote sc (s) 641 associated with the purchased content 113. The transaction information 642 shown in FIG. 6 represents the fork easy identification code 535 and the end user name (not shown in the figure). The transaction data 642 is encrypted using the public key 621 of the clearing house 105. Alternatively, use a digital signature of the electronic digital content store 103 to sign the transaction sC (s) 640 ° In step 605, upon receiving the transaction SC (s) 640 (and included in the transaction SC (s) 640) Quotation Sc (s) 641), the end-user playback application 195 running on the end-user device ι09 uses an order Sc (s) 65 to request clearinghouse 105 authorization. Order Sc (s) 65〇 includes: from quote sc (s) 641ι encrypted symmetric key 623 and store usage conditions 5i9, from transaction

In another embodiment, the order SC (s) 650 is signed with the digital signature 652 of one of the end-user devices 109. When the order SC (s) 650 is received from the end-user device 109, the clearing house 105 verifies the following ·· 1 · Electronic Digital Content Store 1 03 Obtained authorization from the secure digital content electronic distribution system 100 (existing in the clearing house 105 database 160); 2 · The order SC (s) 650 has not been changed; 3 · The transaction data 642 and the symmetric key 623 are complete and trustworthy; 4. The use conditions 519 of the electronic store purchased by the end-user device 109 are consistent with the use conditions 517 set by the content provider 101; and 5. the application The identification code 551 has a valid structure, and the application identification code 55 i is provided by an authorized electronic digital content store 103. If the Tibetan verification is successful, the clearing house i 〇5 decrypts the symmetric key 623 and the transaction data 642 in step 606, and establishes the authorization permission Sc (s) 66〇, and the authorization permission SC (s) 660 is transmitted to the end-user device 109. The control key SC (s) 660 can carry the symmetric key 623 and the transaction data 642, and the public key 661 of the end-user device 109 is used to encrypt the symmetric key 623 and the X-easy data 642. If any verification is unsuccessful, the clearing house ι05 refuses to authorize the end-user device 109 and notifies the end-user device 109. The clearing house 105 also immediately notified the electronic digital content store of the verification failure message 3). In an alternative embodiment, the clearing house signs the authorization sc (s) 660 with its digital signature 663. O: \ 85 \ 85156 division. D〇c -56- 200304126 After receiving the authorization SC (s) 660, the end-user device 109 will first receive the symmetric key 623 received from the Qingyuan 105 And transaction data is decrypted, and in step 607, the content management site m is requested for content Sc (s) 630. When the content SC (s) 630 arrives in step 608, the end-user device 109 decrypts the content 113 using the symmetric key 623 in step 609, and transmits the content 113 and the parent data 642 to other layers for the purpose of the foregoing Zhu Zhao authorizes the watermark embedding, copy / playback encoding, out-of-order encoding, and further content processing as described in FIG. 5. Finally, in step 610, the clearing house 105 periodically transmits the summary transaction report to the content provider 101 and the electronic digital content store 103 for auditing and tracking purposes. V. Safe Container Object Structure A. General Structure A Safe Container Object (SC) is a structure that contains several components that collectively define the content of a unit 113 or a part of a transaction. These components It also defines relevant information such as conditions of use, intermediary information, and Canadian gold. SC (s) is designed so that the integrity, completeness, and trustworthiness of information can be verified. Some information in the SC (s) can be encrypted so that it can be accessed only with proper authorization. SC (s) contains at least one Bill Of Materials (BOM) component, which has a record of information related to SC (s) and information related to each component contained in SC (s) recording. For each component, a messy algorithm such as MD-5 is used to calculate a message digest 〇Λ85 \ 85156 segmentation. D0C -57- 200304126 is necessary, and then the message digest is included in the BOM record of the component. The digests of the private reading and other components are connected together in sequence, and another digest is calculated using these digests, and then the other digest is encrypted with the secret key of the entity that generated the SC (s) to generate a digital signature. The parties receiving the Sc (s) can use the digital signature to verify all the digests, and thus confirm the integrity and completeness of the sC (s) and all components of the SC (s). The following information may be included as a record in B0M and a dead record for each component. The SC (s) type determines which records need to be included: SC (s) version SC (s) identifier SC (s) type (such as quote, order, transaction, content, intermediary information or promotion, and authorization) SC (s) The date on which the issuer generates SC (s). The expiry date of SC (s). The website of the clearing house is used for the description of the digest algorithm of each component. (The system defaults to MD-5.) 〃 For digital signature encryption. The definition of the clear algorithm is as follows: [Description (the system defaults to RSA) Digital food name (summary after each component is included)) The encrypted SC⑷ of all sequential digests may contain more than one BOM. For example, it contains the original intermediary data Sfv 1 Be (s) T J 丨 Beco SC (S) 620 component BOM), electronic digital content quotients (,, and daggers) account for the extra-neck information, and a

O: \ 85 \ 85156 split .DOC -58- 200304126 new BOMs. One record of the intermediary data SC (s) 620 BOM is included in the BOM of the quote SC (s) 641. The record contains a summary of the intermediary data SC (s) 620 BOM. The summary can be used to confirm the integrity of the intermediary data SC (s) 620, so it can also use the summary of each component stored in the intermediary data SC (s) 620 BOM. Value to confirm the integrity of those components contained in the intermediary information SC (s) 620. The components of the intermediary information SC (s) 620 do not have any records in the new BOM generated for the quote SC (s) 641. Only the components added to the digital content store 103 and the intermediary data SC (s) 620 BOM are recorded in the new BOM. SC (s) can also contain a key description component. The key description component contains records that contain the following information about each cryptographic component in the SC (s): The name of the cryptographic component. The name used when the component was decrypted. The encryption algorithm used to encrypt this component. Indicate one of the key cryptographic keys used to encrypt the component in public encryption, or an encrypted symmetric key used to decrypt the component in decryption. The encryption algorithm used to encrypt the symmetric key. This field is only available when the record in the key description component contains an encrypted symmetric balance used to encrypt the encrypted component. One of the public encryption keys used to encrypt the symmetric golden input. Only the record described by Jin Yu in the composition of Shao Fen contains an encrypted symmetric key and the symmetric gold O: \ 85 \ 85156 segment used to encrypt the encrypted part. DOC -59- 200304126 Key "Encryption Algorithm Identification This seat is only available when the yard is set. If SC (s) does not contain any encryption group, and ^ &gt; is a fraction, there is no key description component. B. Rights Management Language Grammar and Semantics Rights management language contains a number of parameters' values can be assigned to these parameters so that after the purchase of content ', the restrictions on end-users' use of content 113 are specified. Restrictions on the use of content 113 are conditions of use. Each content provider specifies usage conditions 517 for each of its 113 items. The electronic digital answering store 103 interprets the use condition 517 in the intermediary data sc0), and uses the information to provide options for which it wants to quote its customers, and uses the information to add the retail information of the content 113. After an end user selects an item of content 113 to be purchased, the end user device 109 asks for authorization of the content 113 according to the store use condition 519. Before the clearing house 105 transmits an authorized SC (s) 660 to the end user, the clearing house 105 transcends | the store's conditions of use. The required condition 5 19 is the same as the allowable use condition 5 17 specified by the content provider 101 in the intermediary information Sc (s) 620. 'When an end-user device 109 receives the purchased content 113, it uses a watermark tool program to encode the store usage condition 5 19 into the content 113 or the secure storage usage condition 5 丨 9. The end-user playback application 195 executing on the end-user device 109 ensures that the store usage conditions 5i-9 encoded to the content 113 are enforced. The following are some examples of store usage conditions 5 19 in an embodiment where the content 113 is music: O: \ 85 \ 85156 Divide_Doc -60- 200304126 Songs can be recorded. Can play songs several times. c_Overview of the process and processing of secure container objects The content provider 101 establishes an intermediary material Sc (s) 620, and uses the intermediary material SC (s) 620 to define content such as songs, etc.13. The content η) itself is not included in these SC (s), because the capacity of the content in is usually too large for each store 103 and the end user in the pen digits, and cannot be used only for descriptive access. Intermediate data to efficiently download container objects. sc (s) instead contains an external Uniform Resource Locator (URL) pointing to the content 113. SC (s) also includes: any descriptive information about the content 113, intermediary material, and any other relevant information about a CD cover picture in the case of music, and / or a digital audio clip in the case of song content 113 Information. The pen digital content store 103 downloads its authorized intermediary data sc (s) 620 and creates a quote sc (s) 641. In summary, the offer SC (s) 041 contains additional information added from some components of the intermediary data SC (s) 620 and the bom, and the electronic digital content store 103. When the quote Sc (s) 641 is created, a new BOM for the quote SC (s) 641 is generated.

An API is executed to create a SC (s) encapsulation tool program interface, and the API accepts the following parameters as input: an indicator of a buffer of each sequential structure. Each structure in the buffer is a command to the encapsulation tool program and the information required to execute the command. Encapsulation tool program commands include: adding a component to an SC (s) with an associated BOM record, adding a record to the BOM, and adding a record to the key description portion. One of the number of sequential structures contained in the above buffer. The name and location of the BOM component. Each bit is one of a designated or reserved flag for future use. The following flags are currently defined:-Indicates whether all components of the SC (s) should be combined into a single file after all structures in the buffer have been processed. When building an SC (s), combining the components into a single object is the last step. -Indicates whether digital signatures are omitted in the BOM section. If this flag is not set, the digital signature is calculated before SC (s) is combined into a single object. In an alternative embodiment, several APIs execute an encapsulation tool programming interface used to create an SC (s), and the APIs accept the following parameters as input: first call an API to generate a bill of materials (BOM) section The method is to send an indicator of a structure, and the structure contains some information used to set the starting value of SC (s). This information includes the IP record O: \ 85 \ 85156 division in the SC (s) BOM part. D0C- 78- 200304126 record, the name used for the BOM part, a system preset location to find one of the parts to be added, and a flag value.

The API accepts an S C (s) identification value previously returned by a previous encapsulation tool API, a pointer to a structure containing information related to the added composition, and a flag value. Information related to the added component includes: the name and location of the component, the name of the BOM used for the component, the type of the component added, a messy value of the component, and flags, etc. . After all the components are added to the SC (s), an encapsulation tool API is called to encapsulate all the components including the BOM part into a single SC (s) object, and the single SC (s) The object is usually a file. The API accepts: an SC (s) identification value previously returned by the previous encapsulation tool API, the name of the SC (s) to be encapsulated, and a piece of information to identify the SC (s) A structured index, and a flag value. The entity of the encapsulation tool program or the calling encapsulation tool program can use an SC (s) template to create an SC (s). The SC (s) template has information used to specify the components and records required in the SC (s) being created. The template can also specify the encryption method and gold reference position used to encrypt the symmetric key 623 and each encryption component. The encapsulation tool has an API for opening a SC (s). Opening a SC (s) is to obtain a SC (s) and divide the SC (s) into its individual components. O: \ 85 \ 85156 Divide. D0C -79- 200304126. The encapsulation tool can then be called to decrypt the encrypted components opened from the SC (S). B. BOM part When creating an SC (s), the BOM part is generated by the encapsulation tool program. The BOM is a text file containing information related to the SC (s) and information related to each component contained in the SC (s). Each record in the BOM is on a single line, and a new line indicates the beginning of a new record. The BOM usually contains a summary of each component and a digital signature that can be used to confirm the trustworthiness and integrity of the SC (s). The types of records in a BOM are as follows: IP — IP records contain a set of name = value pairs associated with SC (s).

The digital certificate is transmitted to the digital content owner in a secure manner, and the digital content owner then transmits the digital certificate to the electronic digital content store 103. The clearing house 105 maintains a database of one of its designated digital certificates. Each certificate contains: a version number, a unique serial number, a signature algorithm, the name of the issuer (name of clearing house 105), the valid date range of the certificate, the name of each store in the electronic digits, electronic A garbled library of digital content stores' public keys and all other information signed with the clearing house's secret key. Each entity with the public gold loser 621 of the Foreign Affairs Office 105 can confirm the certificate, and then guarantee that a signed SC (s) with a public key confirmable with a certificate is a valid sc (s). After the private digital content store 1 03 receives the digital certificate generated by the clearing house 105 and the necessary labor / programs for processing SC (s) from the digital content owner, it can begin to provide end users. Available content: 3 quotes. The electronic digital content store 103 adds its certificate to the transaction Sc (s) 64 and uses its digital signature 643 to sign the Sc (s). The end-user device 109 first checks the digital certificate revocation list, and then uses the common key 621 of the clearing house 105 to verify the information in the digital certificate of the electronic digital content store i 〇3 and verify the electronic digital content store 103 is one of the effective distributors of the content 113 on the secure digital Neigu electronic distribution system 100. List of revocation of 105-dimensional digital certificate of Qingcai Institute. The revocation list may be included in an authorization SC⑷660 generated by the alienation 105 as an integral part of the SC (s). End-user devices do not maintain a revocation list,

O: \ 85 \ 85156 ^ flJ.DOC -86-200304126 Therefore, the revocation list can be used as part of the confirmation of the digital certificate of the electronic digital content store 103. When the end-user device 109 receives a license SC (s) 660 ', it is determined whether the sc (s) contains a new revocation list, and if so, it is updated on the end-user device 10 Revocation list for local storage. B. Rights Management Program Quotation SC (s) Analysis-After the end user receives a transaction sc (s) 64 from the electronic digital content store 103 including the quote SC (s) 641, the clearing house 105 clears the transaction from the end user. Receive an order SC (s) 650. The order sc (s) 65〇 contains: a number of components including information related to the content 113 and its use, information related to the sales of the digital digital content store 1 03 of the content 113, and the final purchase of the content 丨 j 3 Information about users. Before the clearing house 105 begins to process the information in the order Sc (s) 650, the clearing house 005 performs certain procedures to ensure that the sc⑷ is in fact valid and has not tampered with the information contained in the sc⑷ . Confirmation 'Clearing house 105 verifies the digital signature and begins the confirmation of order SC (s) 650. Clearing house 105 then verifies the integrity of each component of order SC (S) 650. In order to confirm the digital signature, if there is a signature, the clearing house 105 first uses the public key 66 of the signed entity to decrypt the content of the signature itself 63 1. (The signing entity may be a content provider 丨 〇 丨, an electronic digital content store 103, an end-user device 109, or any combination of the above.) The clearinghouse 105 then calculates the SC (s) Each sequence component extracts O: \ 85 \ 85156 segmentation. DOC -87- 200304126 abstract, and compares the calculated digest with the decrypted content 113 of the digital signature. If the two values match, the digital signature is valid. In order to verify the integrity of each component, the clearing house 105 calculates a summary of the composition and compares the calculated summary with the digital value in the BOM. The clearing house 105 follows the same procedure to verify the integrity of the digital signatures and components of the intermediary information and quotation SC (s) 641 contained in the order Sc (s) 65. The transaction and quotation SC (s) 641 digital signature verification procedure also indirectly verifies that the electronic digital content store 103 is authorized by the secure digital content electronic distribution system 100. The above procedure is based on the clearing house i 05 as the issuer of the certificate. In addition, the clearing house 105 can also successfully verify the digital signatures of transaction SC (s) 640 and quoted SC (s) 641 by using the public key of electronic digital content store 103, but only when the SC (s) 641 is signed s) can only do so when the entity has ownership of the associated secret key. Please note that the clearing house 105 does not need to have a local database of the electronic digital content store 103, because this store uses the public key of the clearing house to sign the transaction Sc (s) 640 and quote SC (s) 641 Public Kim Yu. Qingyi 10 5 then confirms the store use conditions 519 of the content 113 purchased by the end user, so as to ensure that the store use conditions 519 are included within the limits set in the intermediary data SC (s) 620. As mentioned earlier, the intermediary information SC (s) 620 is included in the order sc (s) 650. The gold loss processing was completed after the order SC (s) 650 was successfully checked for reliability and completeness, the confirmation of the electronic digital content store 103, and the use conditions of the store 519 ΟΛ85 \ 85156. DOC -88- 200304126 The 105 performs processing of the encrypted symmetric key 623 and the watermark instruction. The SC (s) 620 part of the SC (s) 650 can usually have several symmetric keys 623, and these symmetric keys 623 are located in the key description part encrypted by the public key 621 of the clearing house 105. When the intermediary data SC (S) 620 is generated, the content provider 101 performs encryption of the symmetric key 623. One symmetric key 623 is used to decrypt the watermark instruction, and the other symmetric key is used to decrypt the content 113 and any encrypted intermediary data. Content 113 can represent a single song or all songs on a CD, so different symmetric keys 623 can be used for each song. The watermark instruction is included in the SC (s) 620 part of the intermediary information in the order SC (s) 650. The content 113 and the encrypted intermediary data are stored in the content Sc (s) 630 on the hosted content website i 丨 丨. The URL and component names of the encrypted content 113 and the intermediary data part in the content SC (s) 630 are included in the key description part of the intermediary data SC (s) 620 in the order Sc (s) 650. The clearing house ι05 uses its secret key to decrypt the symmetric key 623, and then uses the common key 661 of the end-user device 109 to encrypt the parent symmetric key. From the order sc (s) 650, the public key 661 of the end-user device 9 is obtained. The newly encrypted symmetric key 623 is included in the key description part of the license SC (s) 660 that the clearing house 105 returns to the end-user device 1009. During the processing of the symmetric key 623, the clearing house 105 may want to modify the watermark instruction. If this happens, after the clearing house 105 decrypts the symmetrical key 623, the watermark instruction is modified and re-encrypted. The new watermark instruction is included in the license license O: \ 85 \ 85156 transmitted back to the end-user device 10.9. D0C -89-200304126 can be included in SC (s) 66.0 as a component of # sc⑷ . If all processing of the license SC (s) 660 is successful, the clearinghouse 105 returns a license Sc (s) 66 to the end-user device 109. The end-user device 10 downloads Uchiya SC (s) 630 with a license sc (s) 66, and accesses encrypted content 113 and intermediary data. The end-user device 109 also executes the watermark instruction. If the clearing house 105 is unable to successfully process the order SC (s) 650, an HTML page is sent back to the end-user device and the HTML page is displayed in an Internet browser window. The HTML page indicates why Clearing House 105 was unable to process the transaction. In an alternative embodiment, if the user has purchased a copy of the content 113 before the release date set for the sale of the content 113, the authorization license Sc (s) 66 without the symmetric key 623 is transmitted back. . On or after the issue date, the authorization SC (s) 660 is transmitted back to the clearing house 105 to receive the symmetric key 623. For example, the content provider ιιι allows users to download a new song before the release date of a new song, allowing users to download the song before the release date set by the content provider 101, and Ready to play the song. In this way, the content should start immediately on the release date, and the code shoulder is troubled by the bandwidth and download time on the release date. c_ country-specific parameters Clearing House 105 may choose to use the domain name of the end-user device 10 9 and / or the credit card billing address to determine the country location of the end-user. If there are any restrictions on the sales of Content 113 in the country where the end user lives, then Clearing House 1G5 will send the authorized license sg (s) to the most

If the sub-digital content store 103 does not take into account special country rules set by the content provider, the clearing house 1G5 performs all checks it can perform. D. Audit records and tracking Clearing House 1G5 maintains an audit record 150 of information on these operations for each operation performed during the content 113 purchase transaction and reporting request transaction period. This information can be used for a variety of purposes such as auditing of secure digital content electronic distribution systems, report generation, and data extraction (dau, etc.). Qingyi 105 also maintains a billing subsystem for electronic digital content stores 103. Account balance in 182. The digital content owner provided the pricing structure of the digital content store 103 to the clearing house 105. This information may include current specials that the digital content store 103 must accept, volume discounts, and insufficient account Jaw limits, etc. Clearing House 丨 〇5 uses this pricing information to track the account balances of electronic digital Utani Stores 103 and to ensure that these account balances do not exceed the shortfall limits set by the domestic customer provider 101 Clearing house 105 usually records the following operations: · End-user device 1 009 request for authorization permission sc (s) 66〇 The credit card authorization number when clearing house 105 handles billing will authorize permission SC (s) 660 Transmission to end-user device 10 Request for report End-user notification content Sc (s) 63〇 and license Sc (s) 66〇

Certain reports can be generated automatically at fingertip intervals and stored in clearing house 105 so that they can be transmitted immediately upon receipt of a request. The format of the information in the report will be specified in subsequent editions of this document. F. Early account issuance and payment verification Clearing house 105 or electronic digital content store 103 can process billing of content 113. In the case where the clearing house 105 processes the billing of the electronic content 113, the pen digital content store 103 divides the end-user's order into electronic merchants, and (or some) continuous products. The electronic digital content store i 03 then notifies the clearing house 105 which includes billing information for the end user and transaction information for the total amount that needs to be authorized. The clearing house 105 authorizes the credit card of the end user and sends a notice back to the electronic digital content store 103. While the clearing house 105 authorizes the credit card of the end user, the electronic digital content store 103 may charge the credit card of the end user for any physical goods purchased. After an end user device 109 downloads an electronic item, the clearing house 105 is notified and the end user's credit card can be charged. The above step is the last step that can be performed by the end user device 109 using the content 113 O: \ 85 \ 85156 segmentation on the end user device 109. DOC -94- 200304126.

Content Providers A. Overview The content providers 1 in the various electronic distribution systems within the Towking Digital are digital content owners or entities that have rights to content 113. The content provider 101's task is to prepare the content 113 for distribution, and to make the downloadable version of the content 113 available to the electronic digital content store 103 or the retailer to obtain information related to the content 113. In order to provide the highest security and rights control to Uchiya Koshino 101, a series of tools and programs are provided to enable content providers to prepare their content 113 in their business premises and securely encapsulate their content in SC (s), therefore, when the content 113 leaves the domain of the content provider 101, the content 113 is secure, and unauthorized persons cannot access or access the content 113. This method allows the content 113 to be freely distributed through an insecure network such as the Internet without fear of hackers or unauthorized persons from stealing the content 113.

Workflow management program The purpose of this tool program is to arrange, track, and manage the processing activities of content 113. The application can be accessed by multiple users: and can perform content schedules and status checks on remote locations within content provider 101's intranet (intr_t) or extranet (extr_t) . This design allows collaborative processing, in which multiple individuals can work on multiple pieces of content 113 in parallel, and specific responsibilities can be assigned to different individuals, and this person can be located around the world. Refer now to FIG. 8, which is a block diagram of the main procedures corresponding to the workflow management program 154 of FIG. 7. The main program shown in _8 summarizes the content 113 processing functions provided by the tool program described in M. The workflow management process 154 is responsible for providing work to these processes and, when completing its current processes, directs the work to the next required process. The above steps are accomplished using a series of application programming interfaces (APIs), and each processing tool program calls these application programming interfaces in order to perform the following tasks: Retrieving the next job to be processed refers to unsuccessful redundancy of a program instruction and Failure to complete a procedure successfully and the reason for failure-transitional state of the procedure (in order to start some procedures that only require partial completion of a dependent procedure) Adding a comment to a designated procedure can be obtained from the production workflow management program 154 which also has— Use ^ interface, and-exemplify O: \ 85 \ 85156 split DOC -98- 200304126 workflow management program user interface 700 is shown in Figure 7, and the user interface provides the following functions: at each stage of processing One of the specifications that can specify and execute the system default values and conditions. The configuration setting control function allows users to customize the workflow and automate the processing of work schedules. Status query and reporting. Annotate a related job or Instruction to add one or more program work management (that is, pause, release, remove, change priority ( The order of processing)) Each program has an associated and managed by the workflow management utility 154 queue. Requesting all private sequences of work to the workflow management program 154 will cause the workflow management program 54 to suspend the program (tool program) in a waiting state when there is currently no work in the associated queue of the program, or All information related to the job and required to perform the individual procedures of the job2 is sent back to the procedure. If a procedure is suspended in a waiting state, then when the workflow management program 154 places a task on the queue, the procedure resumes processing. The private machine management style of work machine 54 also manages the process or sequence of processing according to a specified set of specifications. If the content provider does not have special processing requirements or needs to set specific preset rules, the content provider HH can set these rules on its own. When the report completes the masterpiece assigned to the program, the program will notify the status of the workflow. The management program 丄 54, and the workflow management program 154 decides which O: \ 85 \ 85156 partition .D〇c -99- 200304126 queues to place the next job according to the specified rules. It is also possible to attach a note indicating no special processing instructions or precautions to the product at any processing step, via program API, or manually via the workflow management program user interface 700 or processor interface. In the preferred embodiment, Java is used to implement the procedures in the workflow management program 154, but other programming languages such as c / c ++, Assembler, and equivalent languages can also be used. We should understand that the procedures described below for the workflow management program 154 can be executed on a variety of hardware and software platforms. Can be distributed in a computer-readable medium: application-style distribution as-a complete system or-a complete system constitutes a private sequence of the "workflow management program i 54, and the computer-readable media includes (But not limited to) electronic distribution methods such as internet, floppy disks, optical disks, and removable hard drives. Referring now to FIG. 8, there is shown a block diagram of the main procedures corresponding to the workflow management program m shown in FIG. The τ column sections outline each procedure and explain the information or actions required for each procedure. 1 · Products and other magnesium actions / information programs 801—The time information required for the process can be obtained. N When the operation has successfully completed all the dependent procedures, the work will be placed in a specific program sequence. A special queue exists in the workflow management program 154, and the special queue is used to store tasks that cannot be currently processed due to lack of information or failure to perform further processing. These tasks are put on the product waiting list ^ Information Process_ 宁 列.

When any procedure is completed, it will cause the workflow management program 154 to check the queue L and determine whether any tasks in the queue are waiting for the completion of the procedure (action) or the information provided by the procedure. If this is the case, store the job in the appropriate process queue. 2. New Content Requirement Procedure 802 Scroll Initiator 1 101 determines which secondary product (e.g., a product may be a song or a collection of songs) that it wants to sell and distribute electronically. The initial function of the workflow management program 154 is to enable an operator to identify these products and place these products in the queue of a new content request procedure. The content provider 101 can use the configuration setting options to specify which information is not available on the product selection interface. Enter enough information to uniquely identify the product. You can also choose to include some additional stops, so that when the intermediary data is extracted, it is required to manually enter the bexun required to start the audio processing stage. Provided, you can choose to retrieve the information from the system's default configuration environment, or from the content provider's database 160, as in the automatic intermediary data acquisition process 803, This information is obtained in the first stage of the mediation data processing. The structure and capabilities of the content 113 in the content provider's database 160 determine the content selection process. If the necessary information required to query the database 16 of the content provider 101 is specified, the automatic intermediary data acquisition program 803 will handle the job O: \ 85 \ 85156 division.

If the product is retained, the job is added to the new content request process 2 hour list, while waiting for further action to complete the data entry, and / or release the product for processing. -Once the product is released, the program 154 evaluates the specified information and decides the procedures to which the work is to be transferred. If the appropriate information is provided and the database 16G of the content provider 101 can be queried automatically, the work is placed on the 8G34 sequence for automatic intermediary data acquisition and ordering. If the configuration of the database mapping table is not set up for the automatic intermediary data acquisition procedure, then this task is placed in the list for the manual intermediary data input procedure 804 (see section 803 of the automatic intermediary data acquisition procedure) Details about the database mapping table). If the general information required for bone processing and the specific information required to add a watermark are added, then the job is placed in the queue for adding a watermark process (the first stage of content processing) ). If the information required by I is lost when the job is released, the job is placed on the queue of the product waiting action / information program along with the complaint indicating the loss of the information.

If this is not the case, then these tasks are put on the queue of the encryption program 811. If the third-party supplier of the coding tool program does not provide a method to display the percentage of content 113 that has been processed, such as audio, or does not mention 2-a way to indicate that the entire selection of selected content 113 has been coded Rate &lt; Wanfa, then a method for determining the encoding rate of digital content by the content pre-processing and compression tool program shown in FIG. 8 is shown in FIG. At the beginning of the method, the required coding algorithm and bit transmission rate are selected in v 翳 1 1 0 1. However, a query is performed in step 1102 to determine the algorithm and encoding rate. 疋 Does it have a pre-calculated rate factor. The rate factor is used to determine, compress the special encoding continuation method and a specific bit transmission rate and compress it. If the Q factor is not stored in any previously calculated rate factor, then Copies the contents of 13 samples in time. In the preferred embodiment, the predetermined period of time is a few seconds. The encoding rate is used to calculate a new rate factor 'over a predetermined period of time. In step 1108, when the length of time and the amount of encoded content 113 are known, a new, “,” and RNEW are calculated as Rnew = (length of encoded digital content) / (length of time). In step In 11〇9, the content 113 is encoded, and the encoding status is displayed using a rate factor Rnew of ten counts. Then, the encoding rate factor is stored in step O: \ 85 \ 85156 divided by Doc -107- 200304126 1107. rnew for future use of this encoding variant and encoding bit transmission rate. In step 丨 03, if the selected nose rendering method has a previously calculated rate factor Rst〇red 1104, the content 113 is encoded , And use the previously calculated rate factor Rstored to show no progress. At the same time, in step 1105, calculate a current rate factor for the selected differentiation method and bit transmission rate ^ ⑽ for financial gain. In step In 1106, the current rate factor Rcurrent is used to update the average value of the stored rate factor rnew = (Rst〇red + Rcurrent). This repeated update of the rate factor continuously uses a specific encoding algorithm and bit transmission each time. Rate The encoding rate decision can be made more and more precise. After cooking, the new rate counter is stored in step 1107 for future use. If the current rate factor Rcurrent exceeds the previously stored rate factor Rst〇red to one For a specific range or critical value, you do not need to update your mind. Then you can provide a display of the encoding status. The encoding status includes: Under the current encoding rate, according to the encoding rate and the total project length of the content, The percentage of Shao content 1 1 3 is displayed as a barbarian. The coding status of the child may include the remaining coding time. The content 丨 ^ ^ ^ ^ ^ ^ ^ ^ ^ Divide the length of the private case by the "quota" and "flat rate" Rcurrent to calculate the remaining coding time. The coding status of the private child can be transmitted to another, and used in the calling procedure of the child. This This method can assist the supervisory program to encode and approve each phase of #w, private mode, in order to get more efficient processing. I am willing to benefit △ 丨 Small people§ Understand that in an alternative case, the encoding Can include plus Steps into the watermark.

This procedure is an optional step that allows the user to confirm the content f of the content processing performed up to the destination W. This program has no dependencies on other programs except for the completion of the encoding part of the watermark program 808 and the preprocessing and compression program 809. Upon completion of the content quality control process, you can have the following options: You can release the job and place it in the encryption program 8m. Annotations can be appended 'and one or more jobs can be relocated to the queue of the pre-processing and compression program 809. The last option requires that the unencoded but watermarked version of the song file remains available until after the content quality control procedure has been performed. 11. Encryption program 811 The encryption program 811 calls the appropriate secure digital content electronic distribution rights management function to encrypt each watermarked / encoded song file. This program has no dependencies on other programs except for the completion of all other audio processing. When the encryption program 8 is completed, the work is placed in the queue of the content SC (s) generation program 812. 12. Content SC (s) generation program 812 The content SC (s) generation program 812 may need to include certain intermediary data files in the content SC (s) 630. If files other than content U3 are needed, collect these files' and call the SC (s) encapsulation procedure to generate a content Sc (s) 63 for each compression level of the generated content 113 (eg, a song). . Upon completion of the content SC (s) generation program 812, the song will be placed in the queue or content of the final quality assurance program 813 in accordance with the prescribed workflow rules'.

D. Content processing tools Cheng Gu processing tools Cheng Shi 1 "Yu Le e, Ding, Shangying used to process digital content files plus watermarked, encoded, and encrypted content, a group of software workers ^ Programs. These tool programs use industry standard digital content processing tool programs, and when the technology progresses, they can be replaced in a plug-in manner with watermarking, encoding, and encryption technology. If they can be loaded via a command line system call interface The selected job Standard tool program, and pass parameters to the child program, or provide a tool private package that can call functions through a DLL interface, which can automate the content processing to a considerable degree. A front end of each tool program The application queries the content processor and whether there is the next work available in the queue in the program 155. Take the required fields and parameters, and then load the industry standard content processing tool program in order to execute the required When the task is completed, if the program does not report the termination status, you may need to update the card manually. The general version of the content processing tool program 155 will now be explained, but the user-defined version Is also possible. The content processing tool program 155 can be written in Java, c / c ++, or any equivalent. The content processing tool program 155 may be distributed using any computer-readable device including a floppy disk, a compact disc, or the like, or via a website. 1 · Watermark tool program

O: \ 85 \ 85156 辄 DOC -127- 200304126 The watermark tool program allows users to execute the watermark adding procedure 808 described above. The utility uses audio watermarking technology to apply copyright information of 113 content owners to song files. The content provider 丨 〇 丨 and the specific watermark technology determine the actual information to be written. The front-end watermarking tool program can obtain this information, so the watermarking tool program can properly transmit the information to the watermarking function. In this way, there is a synchronization requirement for the intermediary data assimilation and input tool program 161 in order to ensure that the intermediary data assimilation and input tool program 161 obtains the information before allowing the audio file of the song to be processed. Until the watermark information is obtained, audio processing of remote songs will not be possible. The application of a watermark is the first step in audio processing because this step is a simultaneous synchronization of all encodings of the song being composed. As long as the watermark can pass the test of the coding technology, it only needs to perform the watermarking procedure once for each song. Various watermarking techniques are well known and available on the market. However, Saki's &gt; Yu watermark tool program can support a variety of industry standard floating tool programs. 2. Pre-processing and compression tool program The pre-processing and compression tool program allows the user to execute the "pre-processing and compression program_" described above. Audio coding involves two procedures: the implementation of the PCM audio stream in the music content example—a known compression algorithm. The encoder can usually be adjusted to produce a variety of Play bit stream transmission rate. Lightweight quality will cause larger file capacity 'and because of high quality:

O: \ 85 \ 85 丨 56 divided. DOC -128- 200304126 Π 3's file capacity may become too large, so the download time of high-quality content 1 丨 3 may become too long, so sometimes the use of standard The 28,800bps modem. Therefore, the internal customer service provider 010 may provide a variety of digital content quality for downloading, so as to satisfy customers who are impatient and use a narrow-band network. These customers do not want to spend several hours waiting for downloads. Customers using a broadband network, these customers either buy only high-quality content 113 or have a higher speed connection. The compression algorithm has changed in its technology in order to produce a lower bit rate reproduction of the content. Algorithms (ie mpeg, ac3, MRAC) and compression levels can be used to change this technique. &amp; In order to obtain a higher compression level, the data is usually resampled with the lowest sample before being sent to the compression algorithm. In order to get more efficient compression with less loss of facsimile, or to avoid extreme signal loss in some frequency ranges, digital content may sometimes need to adjust the equalization level of some frequencies, or Adjust the dynamic range of the recording. The content pre-processing requirement is directly related to the compression algorithm and the required compression level: generation. In some cases, content (113 = genre) can be successfully used as a basis for determining pre-processing requirements, because songs within the same -Γ: type usually have similar dynamic patterns. The use of a certain-pressure Γ makes :: h 'these pre-processing functions are the pre-processing required by the -part of the encoding process. Time, before performing the compression, the first song also has a downloadable audio file

This coffee code is also the responsibility of the content processing tool program 155. The content provider does not provide the segment as a stand-alone PCM file, or as an offset and length parameter. As in the case of watermarking, we want to load encoding tool programs through the “muscle or command line system call interface” and send all necessary: parameters to these encoding tool programs for pre-processing and compression. For example, if the content is music, and if it is decided to obtain the type of the song from the content provider's database 16G before performing any audio processing, the end-encoding tool program may be required to synchronize with the intermediary data assimilation and input tool program. The above situation depends on the selected coding tool program and the searchability of the song category. If the content provider changes the compilation of ', ·, etc., for each song', then the information is also provided before the encoding step. I The information is interspersed with the intermediary data assimilation and input tool program i6i The information is consistent. Objective: Various high-quality encoding algorithms and tools are known. The 'front-end coding tool program can support a variety of industry-standard coding tool programs. Referring to Fig. 12 ', a flowchart of an embodiment of the automatic Ipe material retrieval tool program shown in Fig. 8 according to the present invention is shown. This program starts 2 The media read-identification code that is being inspected by the provider # 1G1. Content. ^ This is an embodiment of a music CD.

In step ^ ⑴, in an appropriate playback device (eg, a music CD turntable for music cd, a DVD player for DVD movies, a DAT recorder for dat digital ^ cassettes or equivalent) Read the content identification code. Then, in step 1202, the database 160 of the content provider is searched using the identification code as an index. In step 1203, all or part of the information required by the workflow management process shown in FIG. 8 is retrieved from the database 16 and any other related resources. The information may include the content 113 and intermediary information related to the content 113. In step 1204, the captured additional information is used to start the workflow management program 154 in order to generate electronic content. We know that several selected media such as several music CDs can be placed in the queue, so that The automatic intermediary data acquisition tool program was able to generate a series of inner valleys for power distribution. For example, all content 113 may be generated from a series of cds, or even all selected content from one or more selected CDs of one or more CDs viewed by the content provider 101. In an alternative embodiment, the pre-processing parameters can be automatically retrieved from the content provider's database. Referring now to FIG. 13, there is shown a method for automatically setting the pre-processing and compression parameters of the pre-processing and compression tool program shown in FIG. 8 according to the present invention. In this embodiment, the content 113 is music. In step ^ ..., the music (content 113) to be encoded in the content processing tool program 155 is selected. In step 1302, the type of the selected music is determined. The type of music can be entered manually, or other available intermediary data such as additional data extracted from the private sequence shown in Figure 12 can be used to determine the sound

Then in step ⑽, use the music type, compression: threshold, and compression algorithm to query which compression parameters should be used in the pre-processing and compression program_. 3 · Content quality control tool program Uchiya quality official tool program allows users to execute the content quality control process 810 described above. This tool program is an optional content processing tool program, and it gives quality technicians the opportunity to re-examine the coded and watermarked content cases and approve or reject the content files based on quality metrics. The quality control technician can re-process the content, pre-code &amp; manually adjust it until the appropriate quality is obtained, or mark the song as re-processing and attach a note explaining the problem. The content provider ΗΠ may set this program step as an optional step or a necessary step in the content processing workflow.纟 After enclosing all SC⑷s of the content (for example-each sc 各 of each song on the CD), an additional optional final quality assurance procedure 813 step is provided, at which time the quality of the content encoding can be tested 'but Able to discover problems early before encryption and encapsulation for more efficient content processing. Therefore, it is highly desirable to ensure the quality of the content in this step, rather than wait until the end of all processing. 4. Encryption tool program Encryption tool program allows users to execute the encryption program 811 described above. Content encryption is the last step of the content processing tool program 155.

When any problems are found, even small text changes require that the kiss be re-established because of the full nature of SC⑷). In order to avoid unnecessary reprocessing time, we strongly recommend the use of intermediate quality assurance steps to ensure the accuracy of the intermediary data. We also recommend that this specific quality assurance step be reserved to confirm the interaction with the song. Reference. If you see a problem, the QA staff can enter a problem description attached to the song and relocate the song to the appropriate processing unit for reprocessing. The status is appropriately updated in the workflow manager 154 to indicate the status of all relevant components of the song. If no issues are found, the content 113 is marked as ready for distribution. G. Content Dissemination Tool Program The content dissemination tool program allows users to execute the content dissemination procedure described above. Once the distribution of content content has been approved, the content content SC will be placed in the content distribution process.

Content acquisition tool program 171 The content acquisition tool program 171 is responsible for connecting to the content promotion website 156 in order to preview and download the intermediary information SC (s) 620. Because the content promotion website is A standard website, so the electronic digital content store 103 uses a web browser to browse the website. The browsing characteristics will vary according to the website design of the content provider 101. These websites may make many The promotional information screen has extensive search capabilities. Other websites may only provide a simple browser interface to choose from a list of song titles, artists, or new releases. All sites contain a selection of intermediary material SC (s) 620, and the intermediary material SC (s) 620 contains all the promotional and descriptive information for a song or an album. In addition, the electronic digital content store 103 can subscribe to content updates and automatically receive updates via FTP. Viewing the intermediary data Uchibuchi tool 1 71 is a web browser assisting application, and when a link to the intermediary data SC (s) 620 is selected on the content promotion website 156, the content acquisition tool program 171 is activated. When the user selects this item, the content acquisition tool program 17 1 is downloaded to the electronic digital content store 丨 〇3, and the assisting application program is started. The content acquisition tool program 171 opens the intermediary data SC (s) 620, and displays the unencrypted information contained in the intermediary data sc⑷620. In the example of a music, the displayed information includes the extracted intermediary data O: \ 85 \ 85156 points' DOC-147- 200304126 173, graphic images associated with the song, and information describing the song, and if A preview segment of the song d is included in the SC (s) 620 of the intermediary material, and the audition segment can also be listened to. In an example where the content 113 is music, if it is provided by the Uchiya provider 101, the promotion information related to the song or album, the album name, and the artist are also displayed. This information is displayed as a series of linked HTML pages in the browser's view. Purchasable content 113, such as songs and lyrics, and intermediary materials that the content provider 101 wants to protect cannot be obtained from the retail content website 180. In another embodiment, the content provider 101 provides optional promotional content for paid download. In this embodiment, the child promotion content is encrypted in the intermediary material § 匸 (3) 62〇. When the specified fee has been charged to the account of the electronic digital content store 103, the financial settlement caused by opening the data can be processed through the clearing house 105. Extracting intermediary data In addition to the ability to preview, the tool provides two additional special functions: intermediary data extraction, and preparation of quotes Sc (s) 641. When the intermediary data extraction option is selected, the electronic digital content store 103 is prompted to enter the path and file name into the location where the intermediary data will be stored. Binary intermediary data such as graphics and music audition clips are stored as separate files. The text intermediary data is stored in an ASCII delimited text file, and the retail content website 180 can then enter the ASC's text file into its database. It is also generated in a separate toc file to describe the eight 8 ( : One table of 11 delimited text files. There are also additional options to support Luzhou in other languages. "

Language Support; abbreviated as NLS). O: \ 85 \ 85156 Segmentation. D0C -148- 200304126 An important piece of information provided in the extracted data is the product identification code. The product identification code is a business processing function of the electronic digital content store 103 used to identify the transaction processing module n5 (for more information, see the section on transaction processing) and the products purchased by users 113 Identifier. The transaction processing module 17 uses the product identification code to appropriately retrieve the appropriate quotation SC (s) 641 from the quotation database 1 8 i for subsequent download to the end-user device 109. The electronic digital content store 103 has complete control over how it will present downloadable content 113 on its website. The electronic digital content store only needs to keep an interactive comparison of the contents quoted to the product identification code 13 in order to properly connect to the secure digital content electronic distribution system 100 tool program. When this information is provided here, the electronic digital content store 103 can integrate the product or content ιΐ3 into its inventory and sales webpage (database) in a manner parallel to the quotation SC (s) 641 procedure. This is because the two programs use the same product identification code to match the product. This situation is explained further below. The quotation SC (s) generation enveloping tool program 153 The electronic digital content store 103 needs to generate a quotation 8 to 0 641 for describing the downloadable content 113 for sale. Most of the data put into the quotation SC (s) 641 are obtained from the intermediary data sc⑷62〇. The content acquisition tool program 171 generates the quotation sc (s) 641 in the following steps: It is removed from the intermediary data SC (s) 620 and does not need to be included in the quotation SC (s) template in the intermediary data SC (s) 620. Components of the specified quote% ⑷641. The configuration setting of the utility program group added to the electronic digital content store 103 is O: \ 85 \ 85156 divided. The DOC -149- 200304126 option specifies an additional required component. Prompt intermediary information SC (S) 620 for quote SC (s) template specified additional must be entered or selected. Call SC (s) encapsulation utility 153 to encapsulate the information into sc (s) format. The intermediary data SC (s) 620 retains the intermediary data to be displayed by the playback application 195 on the end-user device 109. Remove other promotional intermediary data from the intermediary data sc (s) 620 that is only used by the electronic digital content store 103 as an input to its web service database. It also retains the rights management information provided by content providers such as watermark instructions, encrypted symmetric keys 623, and permitted use conditions for designated objects 5 1 7. Then the quotation SC (s) 641 includes the disassembled intermediary information Sc (s) 620. The electronic digital content store 103 also attaches its own use conditions called store use conditions 5 and 9 or the male purchase option to the offer SC (s) 641. The above steps can be done interactively or automatically through a set of preset instructions. If it is set to be processed in an interactive manner, the electronic digital Uchiya store 103 is prompted with a set of permitted object use conditions 517 which is compliant with the content provider 101. The electronic digital content store 103 then selects the option it wants to offer to its customers. These options now turn into new conditions of use or store usage files 5 19. For automatic processing, the electronic digital content store 1 o) has a set of preset purchase options available for all content 113. These preset options are automatically compared with the allowable use conditions 517 specified by the content provider 101, and when both are the same, the preset options are set in the quote SC (s) 641. One-by-one Λ85, 85! 56 segmentation. Doc -150- 200304126 Once the quotation SC (s) 641 is generated, 'the quotation SC (s) 641 is stored in a quotation database 181, and the intermediary data SC (s) ) The product identification code specified in 620 is used as the index of the intermediary data SC (s) 620. When a customer later connects to the quotation database 181 to retrieve the quotation SC (s) 641 for encapsulation and transmission to the end-user customer, the electronic digital content store 103 uses the product identification code to identify the Downloadable content 113 purchased by the customer. For more details, please refer to the instant of the transaction processing module 175. In another embodiment, the electronic digital content store 103 places the offer SC (S) 641 on its website. This embodiment needs to change the offer sc (s) 641, for example, to replace the web address of the hosted content website 1j with the web address of the electronic digital content store 103. 3. Transaction processing module 175 The electronic digital content store 103 transfers the billing work to the clearing house 105. In addition, the electronic digital content store 103 can also directly ask the clearing house 105 for financial services. There are two basic models for handling end-user purchase requests for downloadable content H3. If the electronic digital content store 103 does not want to handle the financial settlement of purchases, and there are no special promotions and incentives that will affect the sale of goods, and it does not use a shopping cart image that batches purchase requirements, The electronic digital content store 103 may optionally provide a link for downloading its content 11 3 directly to the offer sc (s) 641. These quotes Sc (s) 641 will be created with the retail price information contained in the intermediary data. Special price pages showing one of the purchase options with terms of sale are also included in the quote SC (s) 641. This page is created using the same O: \ 85 \ 85156 split DOC -151-200304126 board that was generated when creating the quote sc (s) 64 丨. When the end user clicks on the direct link of the quote Sc (s) 64i, it downloads the quote Sc (s) 641 to the browser of the end user device 109, and launches a container object to open the container object and display the Assistance app for quote page included in SC (s) 641. The web page contains a form for collecting customer information including credit card information and purchase options. This form is then transmitted directly to the clearing house 105 for financial settlement to process. The form can optionally include fields that use end-user credit information or industry-standard regional transaction control routines. An embodiment of the electronic digital content store 103 processing billing will now be described. A more typical model for processing purchase requests would allow the electronic digital content store 103 to handle financial settlement and then transfer the download authorization to the end user. Howmanfa allows the electronic digital content store 103 to integrate the sale of downloadable content ιΐ3 with other goods provided, and sell it on its website, and can perform batch processing of purchase requirements, only through (shopping cart (Image) 5 charges to customers as a person, without the need to charge a separate charge for each download, and allows the digital content store 103 to directly track their customers' purchase patterns and offers special promotions and membership discount options . In such an environment, the quotation of the downloadable inner valley 113 is included in the shopping page of the electronic digital content store, and when the end user selects the content 113, the content 113 is put into a shopping cart. Processing and financial settlement are performed in the same way as the existing shopping model of the electronic digital content store 103. Once the financial settlement is completed, the business processing program of the secure digital content electronic distribution system 100 then calls the transaction processing module 175 to complete the transaction.

Encapsulate this value to a parent S C (s) 6 4 0 ′ network server and then respond to purchase X to send the transaction SC (s) 640 back to the end user device 109. The transaction processing module 1 75 requests three pieces of information from the business processing program of the electronic digital content store 103: the product identification code of the purchased content 113, the transaction information 642, and an HTML webpage or CGI website address confirming the purchase settlement. The product identification code is a value provided to the electronic digital content store 103 in the intermediary data SC (s) 620 associated with the sold content 1 丨 3. The product identification code is used to retrieve the associated quotation SC (s) from the quotation database 1 81 64. The parent data 642 is an information structure provided by the transaction processing function of the electronic digital content store ι03, and This transaction data 642 is then used to correlate the processing of the clearing house 105 with the financial settlement transactions performed by the electronic digital content store 103 and provide the use of the watermark of the content 113 downloaded to the end-user device. Identification information. When the clearing house 105 receives a valid orderable SC (s) 650, the clearing house 105 records a transaction indicating that the digital content store 103 has sold the content 113, and the record includes the name of the end user And a transaction ID 642 of a transaction ID 535. The transaction identification code 535 can provide a comparison of financial settlement transactions. The clearing house ι05 then sends this information back to the electronic digital content store 103 to use it to check whether its account is consistent with the billing statements received from content provider 101 (or its agent). Content providers 101 can use clearing house transaction records 178 to determine which content 113 they have sold 113 and to enable them to make it available to every electronic digit

The information provided in transaction SC (S) 640 and the security and integrity of transaction Sc (s) 64〇 are sufficient to enable clearing house 1G5 to trust that the purchase transaction is valid, and no need to have Further confirmation. However, the electronic digital content store 103 may choose to charge its account (when the clearing house 105 records the transaction and instructs the content provider 101 to the electronic digital content store 103 to have received the payment for the sale of the content 113), Confirmation of the transaction is required. A flag in transaction information 642 indicates the requirement for confirmation / notification. In this case, the clearing house 105 contacts the electronic digital content store 103 and obtains authorization from the electronic digital content store 103 before charging its account and releasing the encryption key 623. The clearing house 105 transmitted the transaction identification code 535 to the electronic digital content store 103 as part of the verification request, and the electronic digital content store 103 was able to pass the request to a previous transaction with the end user Associated. The transaction identification code 535 can be any unique value that the electronic digital content store 103 wants to use and only uses for this function. The parent data 642 also contains a customer name. The name can come from the user name field of the purchase form filled in when the user made a purchase, or from information registered during a user registration process at a previous electronic digital content store 103, or with the information used for the transaction. The official name derived from the credit card information associated with the credit card. The name was then included in the license watermark 527.

This information is included in the license watermark 527, and the end-user device 109 uses this information for copying and playback control. The final parameter required by the transaction processing module 175 is the HTML page or CGI URL that confirms the purchase settlement. The purpose of this parameter is to enable the electronic digital content store 103 to respond to the end user, and the electronic digital content store 103 is a confirmation message using financial settlement and any other information it wants to include in its response message. End user. When the transaction SC (s) 640 is received and processed, the HTML web page and CGI URL are included in the transaction SC (s) 640 'and displayed on the browser window of the end-user device ι09. Transaction SC (s) 640 is an HTTP response from the electronic digital content store 103 to the end user after processing the purchase submission. Sending an SC (s) as a direct HTTP response will force an SC (s) processor to be automatically loaded on the end-user device 109 to assist the application, so transactions can be completed automatically without relying on further end use Initiated actions. This procedure will be described in detail later in this section of the end-user device 109 and the playback application 195. When the transaction processing module 175 is called with the necessary parameters, the transaction processing module Π5 creates a transaction SC⑷64. The transaction sc⑷640 contains transaction data 642, a transaction confirmation HTML web page or reference URL, and other necessary security features of Sc (s). And the transaction processing module 75 captures and embeds the quotation SC (s) 641 associated with the purchase.

When SC (s) is received from the electronic digital content store 103, the clearing house 105, and the hosted content website U1, Liu Lanji launches the application. The application is responsible for all necessary processing of the Sc (s) a line and adds the content 113 to the digital content database 196 of the end user. The playback application 195 is a stand-alone executable application that is loaded by the end user in order to execute the Uchigaya 113 in its digital content database 196, manage its digital content database 196, and, when allowed, A copy of the content 113 is generated. You can write and play applications 195 and SC (s) processor i 92 applications in java, C / C ++, or any equivalent language. In a preferred embodiment, the applications can be downloaded from a computer-readable device such as a website. However, other distribution mechanisms can also be used, such as distributing such applications on computer-readable media such as floppy disks or CDs. It is entirely through the end user web browser 191 to search and browse the content 113 information, audition such as song clips, and select the songs to bet. The electronic digital content store 103 provides a shopping experience in the same manner as many content 113 retail websites currently provide. The difference from the end user shopping via the current online content 113 is that the user device can now choose to add downloadable content 113 objects to their shopping cart.

As part of this installation, a public / secret key 661 pair is generated for the end-user device i 09 for use in processing orders and licensing% ⑷ 660. A random symmetric key (secret user key) is also generated to protect the song encryption key in the license database 197. The secret user key (not shown in the figure) is dispersed into multiple parts, and The key can be protected by storing parts of the key in multiple storage locations on the end-user's computer. The tamper-resistant software technology is used to protect the code in the area so that the key's partitioning method is not leaked And storage location. Preventing access to the key by people, including end users, helps to prevent content 113 from being used or shared by other electronic monthly benefits. For more details on how to use these keys' Please refer to this section of SC (s) processor 192. Anti-tampering software technology is a way to prevent hackers from invading a computer software application without their permission. Hackers usually want to know and / or modify software, In order to remove the restrictions on use. In fact, there is no private program that cannot be cracked. Ting does not call the tamper-resistant software "the reason for guaranteeing untamperable privacy. But cracking is to prevent tampering The work of the security application I will usually deter most of the hackers, because the work consumed exceeds the possible gains. The work here will be to crack the content of the content 113 key. It may be the key to a song on the top. Eight sides of the anti-tampering software technology is from IBM. One product that introduced the code is the IBM Thinkpad 77〇 laptop. The anti-tampering software system is used in this product. To protect the DVD movie player in your computer.

DOC -162- 200304126 Digital content providers such as Hollywood film manufacturers are concerned about the arrival of digital movies and the ease of making perfect copies, so these digital content providers insist on DVD The movies on it must include copyright protection mechanisms with tamper-resistant software making it difficult to circumvent these copyright protection mechanisms. This is a very typical application of tamper-resistant software; this software system is used to enforce the use of certain protected types of content 113. IBM's anti-tampering software places several obstacles in the intruder's path. First, the tamper-resistant software includes technologies that can disable or at least reduce the effectiveness of standard software tools such as debug programs and anti-combination programs used by hackers. Second, the tamper-resistant software includes a self-integrity check, which will detect a single modification, or even a small number of modifications, and cause incorrect operations. Finally, the tamper-resistant software contains vague points that can mislead hackers about their actual operation. The last technology is mostly special technology, but the first two technologies are based on the tools and programs known in cryptography such as encryption and digital signature. c · 1.92 million secure container object processors When the end user sends the last purchase of the goods collected in his shopping cart to the electronic digital content store 103, the end user ’s network 4 is That is, stay connected and wait for a response from the Internet Temple Server. A web server on the electronic digital content store 103 processes the purchase, performs a financial settlement, and returns a transaction sc (s) 64 to the end-user device 109. The web browser activates the SC (s) processor 192 (assistance application 198) to process the Sc (s) multimedia Internet mail extension (MIME) type associated with the transaction SC (s) 640.

After the iron post, the company just offered a quote SC⑷64i in the middle job, and from these quotes sc (s) ’’ ’, the name of the insider 113 (such as a song or album) and the estimated download time are extracted. Then use the information to display a new window in step 1402, and provide the end user with a schedule private option for downloading content 113 (e.g., for bone music τ 'is a song or an entire album). End users can choose to download immediately, or download the women's volleyball team at a later time. If a later time is selected, the download schedule information is stored in a record, and the download is started at the scheduled time when the end-user device 109 is turned on at the scheduled time. If the computer is not turned on at the scheduled download time, or the communication link is disconnected, the next time the computer is turned on, the end user is prompted to reschedule the download time. When the scheduled download time is reached, or an immediate download is required, the processor 192 uses the information in the transaction SC⑷64, the quote% ⑷64i, and the end-user public key 661 generated during installation to generate the order SC ( s) 650. The order Sc (s) 650 is transmitted to the clearing house 105 via an HTTP request. When the clearing house 105 returns the license sc (s) 66, the assistance application 198 is called again to process the license sc (s) 66. Then open the license SC (s) 660, and extract the hosted content website ill URL from the referenced order sc (s) 65. Then via Liu Lanqi ’s Ηττρ * to find the division of O: \ 85 \ 85156.

This method prevents hackers from removing or modifying the watermark. After adding any necessary watermarks to the content buffer, the contents of the buffer are sent with a hex encryption function for re-encryption ^ 194. The content US is re-encrypted using a random symmetric key using a 2-rate secure encryption algorithm 'such as IBM's SEAL encryption technology. Once the download and decryption and re-encryption process 194 is completed, the content provider 101's original encryption key 623, which originally encrypted the content 113, is now destroyed, and the secret user Jin Yu created and hidden during installation is the new The SEAL key itself is encrypted. The new encrypted key is now stored in the license database 107. Unlike the source that is executed at the content provider 101, the user watermark process executed on the end-user device 109 may not need to become an effective industry standard. These standards are still in progress. This technology allows control information to be embedded in the music and updates the control information several times. Before the copy control standard became more stable, an alternative method of copy control had been provided in the secure digital content electronic distribution system 100, so that it was not necessary to rely on the copy control watermark to provide rights management in consumer electronics devices. The encrypted digital content database 196 connected to the end-user device 109 implements security of storage and playback / recording use conditions, and protects the security of the storage and playback / recording use conditions through a tamper-resistant environment. When standard is used, software hooks are used to support copy control watermarks. At present, it can support AAC and other encoded audio streams with various compression levels, but at this time the technology is still not mature enough to be used as ΟΛ85 \ 85156 segmentation. D0C -166- 200304126 The only one for copy control method. The decryption and re-encryption process 194 is another field of code, in which the code is protected by tampering code technology so that the original encryption key 113, the new SEAL key, and secret use are not leaked. Jin Yu, and the secret user's gold loss section and the method of segmenting the key are stored therein. There are two uses for the solution and re-encryption program. Storage utilization, like: When the algorithm WEAL encrypted content 113, faster instantaneous solution can be performed, and it requires less processor utilization than more industry standard types of algorithms such as DES, etc. Perform decryption. In this way, the playback application program 195 can perform a real-time and parallel decryption_decoding-playback of the content 113 without decrypting the entire capture of the content 113 before decoding and playing. The efficiency of the SEAL algorithm and a high-efficiency decoding algorithm can not only perform parallel operations (self-encrypted file streaming playback), but also execute the program on a much less efficient system processor. Therefore, the application can be supported on an end-user device 10, such as a Pentium system with a performance as low as 60 MHz or a system with a lower performance. When the encryption format used by each 113 in the final storage is separated from the original encryption format, there is greater flexibility in selecting the encryption algorithm of the original content. Therefore, widely accepted and tried-and-tested industry standard algorithms can be used, thereby further strengthening the digital content industry's acceptance of the secure digital content electronic distribution system ι〇〇. The second purpose of the child decryption and re-encryption program 194 is to eliminate the need for the original master encryption key used by the content provider 101 to encrypt the content 113.

In another embodiment, the use of the content U3 is not recorded for later upload to a recording website, but the usage status of the content 113 is uploaded to the recording website each time the content 113 is used. For example, when the content 113 stored in the end-user device 109 is copied or copied to a DVD, digital tape, flash memory, MD, or equivalent readable / writeable removable media, etc. When an external device is installed, its usage status is updated on the record website. The above situation may be a prerequisite for the copying of the content 113 in the conditions of use 206 transmitted when the content 113 is purchased. This method ensures that the content provider can accurately track the usage status of its content 113 when playing, copying, or performing other actions on the content 113. In addition, other information related to the content 113 can be uploaded to the Jilu website. For example, the time (date and hour) when the content 113 was last executed; how many times the content 113 has been executed; whether the content 113 has been copied or copied to — an authorized external source such as a DVD, digital tape, or river 0 Device. In the case where there are multiple different users of the release response type 195 on the end-user device, for example, in the case of different members of a family, the content / user identification is transmitted together with the usage information Go to the record website. The content provider 101 checks the usage information uploaded to the recording website, and can measure the popularity of the content 113 according to the actual usage status, the identity of the user, and the number of times the content has been executed.
