O:\85\85156 Split.DOC 1255443 This is less than -$, but always consumes money. However, in the case of electronic distribution, physical media is no longer needed. Because the content is delivered electronically, the cost of physical media is not a factor. The second obstacle is the format of the guest itself, that is, the content stored in a similar format relative to the content stored in the -digit format. # When copying content stored in an analogy format such as a printed image by photocopying, the quality of the copy is lower than the original quality. Each subsequent copy of a copy (sometimes referred to as a generation) is of a lower quality than the original one. When the image is stored digitally, there is no degradation in quality. Each copy and every copy of the copy is as clear and distinct as the original picture. Unauthorized copying and distribution of unauthorized copies is made easier by the perfect digital copy combined with the low-cost use of electronically distributed content and the widespread integration of content over the Internet. By simply pressing a few keys on the keyboard, an illegal copyer can transfer hundreds or even thousands of perfectly duplicated digital content over the Internet. Therefore, there is a need to ensure the protection and security of digital assets that are electronically distributed. The number of insiders is hoping to establish a Queen Digital Valley Global Distribution System that protects the rights of content owners. The problem of establishing a digital content distribution system includes the development of systems for electronic distribution of digital content, rights management, and asset protection. Electronically distributed digital content includes provinces such as print media, movies, video games, programs, television, multimedia, and music. 3 Deploy-Electronic Distribution System enables digital content providers to quickly receive payments via immediate sales returns and electronic reconciliations

Because the digital pre-positioning system is not affected by physical stock out-of-stock or returns, digital content providers and retailers can have lower costs and higher profit margins. Digital content providers can assist with new distribution channels or enhance existing distribution channels to distribute inventory faster. The transaction information of the electronic distribution system can be used to obtain information about the customer's purchase pattern and to provide immediate feedback related to the buns marketing plan and promotion. To achieve these goals, digital content providers need to use an electronic distribution model that enables a wide range of users and businesses to capture digital guilt while ensuring the protection and billing of digital assets. Digital content electronic distribution systems such as real-time audio systems (realaudi0), AT&T's A2b, u(d)d Audio Pro Corp.'s Liquid Audi〇pr〇, c-Music Network, and other systems are available on the market.

Another reason why digital valley owners have slowed down to accept electronic distribution is that these digital content owners want to maintain and promote existing distribution channels. Most content owners are sold through retailers. In the music market, these US retailers include Tower Records, Peaches, Blockbuster, Circuit City, and other retailers. Many of these retailers have a website that allows Internet users to be selected via the Internet and can be emailed to users for purchase. Music sites include @tower, Music Boulevard, and Columbia House. When using electronic distribution, these retail stores may not be differentiated and can't be differentiated from everyone inside, especially on the World Wide Web. Therefore, there is a need for electronic content retailers such as pictures, video games, music, programs, and video products to provide a way of distinguishing between each other and the content owner when selling music via electronic distribution. The content owner prepares his digital content for electronic distribution via a distribution website such as an electronic store. Electronic stores on the Internet or electronic stores via other online services want to differentiate between each other via their product lines and product promotions. Traditional stores (that is, non-electronic and non-online stores that are analogous to e-shops) use product promotions, product clerk, product samples, free return policies, and other promotional programs to differentiate them from competitors. . However, in an online world where content providers have conditions for digital content, the ability of electronic stores to differentiate can be severely limited. In addition, even if the conditions of use can be changed, the electronics

The first bun store needs to receive the media information associated with the digital content from the content provider. Most of the time, the distribution of such mediations may be transmitted in an encrypted manner, so the content provider must establish a mechanism to decrypt the encrypted content. Second, the e-store may wish to pick up from the content provider. (4) Preview the content from the content provider before the content is received, or after receiving the content in the electronic store, to facilitate product marketing, product positioning, and other content-related promotional considerations. Third, the electronic store needs to extract some uses. For mediation materials such as graphics and artists, promotional materials are often used directly by online stores for online promotion. Fourth, electronic stores may wish to modify the conditions under which certain materials are used in order to produce different digital content lines. And it has an alienation with other e-shops. Fifth, e-shops may need to insert certain addresses, such as URLs, into the intermediary material' or change some of the addresses in the mediation data so that the purchaser automatically goes to the account. Payment by the collection agency without having to pay for the e-shop. Sixth, the e-shop may need A license is granted to allow the use of copyrighted digital content in accordance with the conditions of use. For example, the license may agree to a limited number of copies of the digital content. The license must reflect the agreed terms. For all of these requirements, 'in order to process mediation related to digital content, many e-shops write custom-sized software programs to handle these requirements. The time required to develop these custom-sized software programs is O:\85\ 85156 Segmentation.DOC -12- 1255443 This and the test 4 may be quite large. Therefore, there is a need for a solution to these requirements. Digital content owners have slowed down the acceptance of electronic distribution Another reason is to prepare for Difficulties in the content of electronic distribution. Many content providers currently have thousands or even tens of thousands of product content in their product catalog. In an example of a music market, a content owner has several different types of single recording masters at the same time. Formats (such as CDs, cassettes, and MDs) are not too weird. In addition, a single format may pin Re-producing a master tape or remixing a recording master for a particular distribution channel, or for a specific delivery medium such as a CD, MD, tape, DVD, or equivalent media. The sound may be different from the mix for the music track for dance music, or it may be different from the mix of CDs available to the average consumer. Counting and tracking these different mix versions can be quite cumbersome. In addition, many recording masters The owner often reissues old recordings in a variety of subsequent publications, such as re-releases in the form of "selected collections," or arranged in the original soundtracks and other publications series, or in other arrangements. As more content is provided in digital form, the need to remix or re-process and encode content for electronic distribution has also grown. Content owners often need to use the old recording format as a guide to select the correct recording master and reprocess and encode the recordings for distribution via electronic distribution. Content providers who want to use their old format to assist them in reissuing old recordings for electronic distribution are particularly suitable for the above scenarios. The content provider will search the database to match the content name, artist, and recording, and determine the encoding parameters and retrieve the associated content information or accompanying materials, such as

O:\85\85156 Split D0C -13- 1255443 The picture, including the music review, website, access record, long-term listening sample clips, etc. Such a procedure for manually searching for the I-Y, G-Green Content Directory database is not without drawbacks. One drawback is that ^, 疋, and let the operator search for a database in a manual manner and set the processing parameters appropriately. Another disadvantage is that the operator may have a chance of copying errors when selecting data from the database. Therefore, it is necessary to take a picture of the relevant information and recording master tapes such as the contents of the first and the other. The content owner prepares it for electronics via a program called encoding

Digital content for distribution. Encoding involves the acquisition of content, and (10) capacity: the digitization of the content when it is presented in an analog format, and the compression of the content. This compression program allows digital content to be transferred to and stored on recordable media in a more efficient way: cut-and-store, because the amount of material transferred or stored (4) is reduced. However, compression is not without its drawbacks. Most of the compression involves the loss of certain information and is therefore called lossy compreSslGn. @容Provider must decide which compression algorithm to use and

The level of compression required. For example, in music, digital content or songs may have quite different characteristics depending on the type of music. For a certain type, the compression algorithm and compression level may not be the most 4# for the other-music type. The inner valley provider may find that the compression algorithm and the compression level spoon are quite suitable for a certain type of music such as classical music, and the other type of music such as heavy metal f music cannot be full, &quot In addition, the recording engineer often has to adjust the music slightly to adjust the sorrow and sorrow, and perform other pre-processing and processing settings to ensure that the type of music being encoded will produce the desired result. This type of 〇: \85\85156 ^f,j D〇c -14 - 1255443 - Λ, 乂 artificially set the need for these coding parameters, such as setting the equalization level and dynamic compression and expansion for the mother-digital content The need to set values can be cumbersome and costly. Returning to the example of music, a content content provider that covers multiple music types will have to manually select each song or group of songs to be encoded, and the desired combination of encoding parameters. Therefore, there is currently a need for money to manually select the encoding parameters. Programs that compress content may require a large amount of dedicated computing resources, especially for larger content such as full-length movies. The compression algorithm provides the two shores and the four (4) of the pressure (4). These choices include: the length of time required for the content of the I and the computing resources; the amount of dust reduction from the original content. Bit transfer rate; performance quality of compressed content; and other factors. When a code program uses a multimedia file as input and generates a coded output structure, but there is no process or state = during the transition period, the twist There will be problems with this encoding program. In addition, in the '•牛夕k开 y, use other programs to call or manage a coded program with no transition during the transition period. The application will be called at this time. The amount of encoded content cannot be measured as the percentage of the complete selection specified to be encoded. The program at the call is attempting to schedule several different programs to execute immediately: 'The above situation will cause problems. In addition, within the selected code to be encoded When the batch/person and the Neigu provider want to decide the progress of the encoding process, the I·month opening/疋 of the previous article 4 is quite cumbersome. Therefore, there is a need to solve this problem. The way the problem within the next few bits k Valley donors have yet another reason to slow down the use of electronic distribution

O:\85\85156 Split.D0C -15- 1255443 is: its content lacks the standard for generating a digital player on a user device for electronically transmitted content. Content providers, e-shops, or other members of the electronic distribution chain may want to provide custom-formatted 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 for decrypting digital content in a tamper-resistant environment (i.e., an environment that prevents unauthorized access to content while a third party is playing). In addition, a set of tools is required to enable a user to manage a native digital content library, but the set of tools does not allow the user to access content that is not purchased for use.

System Overview Secure Digital Content The electronic distribution system is a technology platform that includes the secure transfer of digital content and digital content related internals to the user's client device and the rights management of such content. Technology, regulations. Work eight private, and software. User devices include personal computer systems, video converters (IRDs), and internet devices. These devices may copy the content to an external media or a portable appliance that is approved by the content owner. The term Digital CGntent or Content (4) Gift (10) means information and materials stored in digital format, including: pictures, movies, video programs, bone music, programs, multimedia, and video games. The technology platform stipulates how to prepare for digital enthusiasm, such as busy peer-to-peer or broadcast infrastructure (such as cable, internet, security, long-term power line)

O:\85\85I56 Split.DOC -22- 1255443 Securely distribute, how to authorize the user device, and how to prevent unauthorized copying or playback. In addition, the architecture of the technology platform can be integrated or ported when various technologies, such as floating =, compression/encoding, encryption, and other security algorithms, progress over time.

The basic components of the Anwang digital valley distribution system include: (U rights management for ownership protection of content owners; (7) transaction counting for immediate and accurate compensation; and (3) an open and documentary The detailed structure allows the content provider to prepare the content, and allows the content to be safely distributed on the network infrastructure for playback on any standard-compliant player. The secure digital content electronic distribution #, the rights management in the system is implemented through a set of functions distributed between the working components of the system. The functions of the king include: · licensing and control, so that the content can only Authorized intermediaries or end users that are acquired-authorized to decode; and use of content based on terms of the purchase or license, such as the number of copies allowed, the number of plays, or the time interval or period during which the license is valid Control and enforcement. The secondary function of entitlement management is to activate a device to identify unauthorized content. The origin of the shell, in order to combat the 1 1 , the implementation of the Secure Container (Secure Container; sc) technology and the implementation of the license: the system clearing has been successfully completed - after the (four) tradable, (four) between people or the final use Can decode the content to provide authorization

ΟΛ85\85Ι56 Split.DOC •23 - 1255443 Yes. The safe container object is encrypted with the step + f, and the wood is used to distribute the encrypted inner and outer bells between the components of the system. The SC is an encrypted information or content carrier that utilizes encryption, digital signatures, and digital certificates to intercept or modify electronic information from time to time. This % also verifies the reliance and integrity of digital in the future. The advantages of these rights management functions are: Electronic digital content distribution infrastructure does not have to be secure or trustworthy. Therefore, it can be transmitted via network infrastructure such as the World Wide Web and the Internet. This is due to the fact that the content is encrypted within the secure container object and the storage and distribution of the content is isolated from the decryption and use of the content. Only the user with the decryption key can decrypt the encrypted content, and the clearing house only issues the decryption key for authorized and appropriate usage requirements. The clearing house will not approve additional requirements from unknown or unauthorized persons, or will not meet the requirements for content usage conditions set by the content owner. In addition, if an SC is tampered with during the transmission of the content, the software in the clearing house determines that the sc has been tampered with or forged and refuses to accept the transaction. Control of content usage is initiated via an end user playback application (195) executing on an end user device. The application digitizes a digit code into the parent's copy, which specifies the number of copies and playbacks that can be tolerated. The digital watermarking technique is utilized to generate the digital code so that other end user playback applications (195) cannot know the digital code and make the digital code resistant to attempts to change. In an alternate embodiment, the digital code is only saved as part of the usage conditions associated with the content (113). When the digital content (u3) is accessed in a standard-compliant end user device, the end user playback application (195) reads the watermark to check 0:\85\85丨56 split.DOC-24 - 1255443 Check the usage limit and update the watermark as needed. If the required use of the content does not meet the conditions of use, such as when the number of copies is exhausted, the end user device will not perform the request. Digital watermarking also provides a way to identify the source of authorized or unauthorized copies of content. The content owner embeds an initial watermark in the content to identify the content owner, specify copyright information, specify a geographic location, and add other relevant information. A second watermark is embedded in the content of the end user device to identify the content purchaser (or license) and end user device, specify the purchase or license conditions and date, and add any other relevant information. Because the watermark becomes an inseparable part of the content, the copy is necessarily carried in the content, whether the copy is authorized or unauthorized. Therefore, regardless of where the content is stored, regardless of the source of the content, the digital content necessarily contains information about the source and permissibility of the content. This information can be used to combat the illegal use of content. 2. Measurements The clearing house retains records of all transactions approved for exchange of keys through the clearing house as part of its rights management function. This record measures the license and the original conditions of use. The transaction record can be returned to the responsible parties such as content owners or content providers, retailers, and other related partners in an immediate or regular <RTIgt; manner, to facilitate electronically reconciling the parental payment And other uses. 3. Open Architecture Child-safe digital content electronic distribution system is an open architecture,

〇:\85\85丨56 Division.D0C -25- 1255443 $ has published specifications and interfaces, and helps to implement and accept the system widely in the market, while maintaining the rights protection of the content owner. The flexibility and openness of the system architecture also allows the system to evolve over time as technology, transmission infrastructure, and devices enter the market. The architecture is open to the nature of the content and its format. The architecture supports the distribution of audio, program, multimedia, video, or other types of content. The native format such as linear pCM for digital music can also be passed through such as chopping, compression, or pre-processing. A format obtained by emphasizing/de-emphasizing additional pre-processing or coding. This architecture is open to a wide range of encryption and watermarking technologies. The architecture can select specific technologies to accommodate different content types and formats, and can import or adopt newly developed technologies. This resiliency allows content providers to select and upgrade their technology for data compression, encryption, and formatting within a secure digital distribution system. The architecture is also open to different distribution networks and distribution models. The architecture supports content delivery over low-speed Internet connections or high-speed satellite and cable networks, and can be paired with point-to-point or broadcast models. In addition, the architecture is designed to implement functions in the end user device on a variety of devices including low cost consumer appliance devices. Such a device allows content providers and retailers to provide content to middlemen or end users via multiple service types, and allows users to purchase content or obtain authorization for content, play the content, and play the content. Recorded in a variety of standards-compliant playback devices. O:\85\85156 Split. DOC -26- 1255443 系统 System Function Components Referring now to Figure 1, there is shown a block diagram of an overview of a secure digital valley electronic dispensing system 100 in accordance with the present invention. The secure digital content electronic distribution system 100 includes a plurality of business components including an end-to-end solution 2, the business components including: a content provider 101 or a digital content owner, an electronic digital content store 103, and an intermediate market partner (figure Not shown), clearing house 105, escrow content website m, transmission infrastructure 1〇7, and end user device 1〇9. Each of these business components utilizes various components of a secure digital content electronic distribution system. A high-level description of these business components and system components related to the distribution of electronic (IV) 113 will be given below. 1. Content Provider 1 内容 The content provider 101 or content owner is the owner of the original content 113, and/or the distributor authorized to make the independent content 113 a kit for further distribution. The content provider 101 can directly utilize its rights, or authorize the content 113 to the electronic digital content store 103, or an intermediate market partner (not shown), and typically reclaim content usage payments associated with the e-commerce revenue. Examples of the current I 疋 donor 101 include s〇ny, Tim Bu Warner, MTV,

Microsoft, Turner, Fox, and other content providers. The content provider 101 uses the various tools provided as the alpha-partition of the secure digital content electronic distribution system 100 to prepare its contents and related materials for distribution. A workflow management program 154 arranges the time schedules of the respective 113s to be processed, and tracks the content 113 as the content 113 passes through the steps of content 113 preparation and kit composition in order to maintain excellent quality.

〇: \85\85丨56 Division. D0C -27- 1255443 X In the present document, the term intermediary material means a reading related to the content (1), and the content 113 itself is not included in the present embodiment. For example, Lu, the mediation of a certain song may be the song name or the consumption of the song = not the recording of the song. Content 113 will contain the recording. An intermediary, 'Double Assimilation and Knowledge Tool 161 uses data from the Content Provider Database = Extract Intermediary Materials' or extracts content provided by the content provider in a specified format (in the case of a music, such as a CD name, artist) The name, song name, and CD picture and other content 113 information), and these materials are combined into a kit for private distribution. The mediation data assimilation and input tool program 161 is also used to input the usage conditions of the respective 113s. The information in the conditions of use can include copy restriction rules, wholesale prices, and any business rules that must be $. The watermarking tool program is used to hide the content of the content 113 for identifying the date of processing of the content owner, and other related materials. In an embodiment where the content 丨丨3 is a sound, an audio pre-processing tool is used to adjust the dynamic range of each 113 or other Jinxun, and/or equalize the content to obtain the best compression quality. And compress to the desired compression level and encrypt the content 113. These tools are adaptable to follow the technical advances in digital content compression/encoding, encryption, and formatting methods, allowing content providers 101 to take advantage of the best tools when new tools are available on the market. . The SC Encapsulation Tool program encapsulates encrypted content 数3, digital content-related or intermediary data, and encryption keys in each of the Scs (described below) and stores them on a web content site and/or ) Promotional website for electronic distribution. Hosted content sites can be located in content providers 1 or in multiple sites

O:\85\85156 Split.DOC -28 - 1255443, including the electronic digital content store 103 and the intermediate market partner (not shown). Because the content 113 and the key (described below) are encrypted and encapsulated in each SCs, the electronic digital content store 1〇3 or people and other website hosting companies cannot approve and notify the content without going through the clearing house. In the case of the donor 101, the decrypted content 丨丨3 is directly accessed. 2. Electronic Digital Content Store 1 电子 3 The electronic digital content store 103 is an entity that sells content 113 via various services or applications such as a sales plan with the theme 113 as the theme or an electronic promotion of the content 113. The Electronic Digital Content Store 1〇3 manages the design, development, business operations, checkout, promotion, and sales of its services. An example of the online electronic digital content store 103 is a website that provides electronic downloading of software. The electronic digital content store 103 performs certain functions of the secure digital content electronic distribution system 1 in its service park. The electronic digital content store 103 aggregates information from the content provider 1.1, encapsulates the content and intermediary information in additional SCs, and transmits the SCs to the consumer or business as part of a service or application. The Electronic Digital Content Store 1〇3 uses the tools provided by the Secure Digital Content Electronic Distribution System to assist in the following: mediation data extraction, secondary usage conditions, 8 (: encapsulation, and electronic content transactions) The secondary usage condition data may include retail business quotation materials such as content 购买3 purchase price, billing price, copy authorization and target device type, or available time limit, etc. Once the buns digital content store 103 completes a final use. After the valid request for the electronic: capacity 113, the electronic digital content store 103, ie, the negative clearing rights clearinghouse 1〇5, sends the decryption key of the content 113 to the customer.

The digital content store may choose to place each scs containing digital content on its own website, and/or may choose to utilize a web hosting and delivery facility of another hosting content website. Electronic digital content stores can use the secure digital content electronic distribution system 100 to provide customer service to questions or questions that may be raised by end users. The electronic digital content store 1G3 can also outsource its customer service support to the clearing house 105. 3. Intermediate Market Partner (not shown) In an alternative embodiment, the secure digital content electronic distribution system 1 can be utilized to provide content 113 to other businesses known as intermediate market partners. These partners may include digital content-related companies that provide non-electronic services, such as a television station or video club that distributes content U3, a radio station, or a record club. These partners may also include other trustees such as recording studios, copying companies, producers, etc., who process materials for local sound production or marketing. These intermediate market partners require the approval of the clearing house 105 to decrypt the content 113. 4. The clearing house 105 clearing house 105 provides authorization and record keeping for the sale and/or permissive use of the content 113 encrypted in an SC. When the clearing house 接收5 receives a request for a decryption key for the content 丨丨3 from an intermediary or end user, the clearing house 105 confirms the integrity and trustworthiness of the requested information; The digital content store or content provider 101 has authorized the request; and the verification requires that the usage meets the content usage conditions specified by the content provider 1.1. Once these verifications are met, the clearinghouse 105 is about to be wrapped up in an O:\85\85156 victim IJ.DOC • 30-1255443. The content of the license sc is decrypted and transmitted to the requesting end user. The key is encrypted so that only authorized users can extend the key. If the end user's request is unverifiable, incomplete, or unauthorized, the clearinghouse 105 rejects the request for the decryption key. The clearing house 1G5 keeps records of all transactions and can report these records to parties such as the electronic digital content store 103 and the content provider 1〇1 in a timely, regular, or limited manner. Such a return is a type in which the content information provider of the internal answer 113 can be notified to the content provider 1.1 and the electronic digital content store 103 can receive the audit report electronically delivered to its customer. If the clearinghouse 105 detects that the information in the sc has leaked or does not match the content usage condition, the clearinghouse 1〇5 may also notify the content provider 101 and/or the electronic digital content store 1〇3. The transaction records and storage capacity of the database of the Clearing House is designed for data collection, storage and reporting. In another embodiment, the clearinghouse 105 can provide processing of customer support and transaction exceptions, such as refunds, transmission failures, and purchase disputes. The clearing house 105 can operate as an independent entity and as a trustee of one of the rights management and measurement. The clearing house also provides services for opening bills and settlements when needed. Examples of electronic clearing houses include Secure_Bank c〇m and Secure Electr〇nic Transaction (SET) established by Visa/Mastercard. In one embodiment, the clearinghouse i〇5 is the website to which the end user device 109 can be connected. In another embodiment, the clearinghouse 105 is part of an electronic digital content store 101. 5. The end user device 1〇9 O:\85\85156 split.

Throughout this document, the terms end user and end user device are used to mean the use or execution on an end user device 1 〇 9. · 6. Transmission Infrastructure 107 The King's Digital Valley Electronic Distribution System 1 〇 〇 is connected to the electronic digital content of the store 103 and the end user device 109. Secure Digital Content The electronic distribution system 1 supports point-to-point delivery modes such as the Internet and broadcast distribution modes such as digital broadcast television. Even though the same tools and applications are used to acquire, encapsulate, and track content 113 transactions via various transport infrastructure 107, they can be partitioned by 85\85156.

The quality of the transmitted content 113 may also be different, because the high-bandwidth transmission infrastructure can transmit higher-quality digital transmissions in a relatively low-frequency wide-based material infrastructure with a more acceptable response time. A service application designed to support a broadcast distribution mode as well. c. System Usage The secure digital content electronic distribution system 100 can securely transfer high quality electronic content 113 to the end user device 109 of the consumer or business to regulate and track the use of the content 113. New and existing distribution channels can be utilized, and secure digital content electronic distribution systems can be deployed across a variety of consumer and business-to-business applications. Each specific service can use a different financial model and can be secured via secure digital content. The financial mode is executed by each rights management of the distribution system 100. The rights management of the clearing house 105 and the anti-copy special function of the end user playing application 195 can be implemented to implement modes such as wholesale or zero-buy, pay-per-use, service, copy/no copy restriction, or re-distribution. . The secure digital content electronic distribution system 1 allows electronic digital content stores 103 and intermediate market partners to have great flexibility in creating services for selling content 113. At the same time, the secure digital content electronic distribution system 100 provides a certain degree of assurance to the content provider 1.1, so that the digital assets of the content provider 101 are protected and measured, and thus the content provider 1〇1 can be content-dependent 113 authorized to receive appropriate compensation. O:\85\85156 Split.DOC -33- 1255443 II. Cryptographic concept and its application in secure digital content electronic distribution system Secure digital content License control in electronic distribution system 100 is based on the use of passwords. This section describes the basic cryptographic techniques of the present invention. Public public key encryption, symmetric key encryption, digital signatures, digital watermarks, and digital certificates are well 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 data sender and the recipient of the message must share the key. The key shared in this article is called a symmetric key. The secure digital content electronic distribution system 1 is independent of the extremely hard symmetric algorithm selected for a particular embodiment. Common symmetric algorithms are DES, RC2, and RC4. Both DES and RC2 are block ciphers. The segment password encrypts the data with one segment of data bits at a time. DES is an official US government encryption standard with a 64-bit segment length and a 56-bit key. Triple DES is often used to increase the security that simple DES can achieve. RSA Data Security designed RC2〇RC2 to use a variable-key length password with a 64-bit segment length. Also designed by RSA, RC4 is a variable stream cipher of variable length. The bitstream cipher is computed 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 Split.D0C -34- 1255443 IBM designed a fast algorithm called SEAL. SEAL is a bitstream algorithm that uses a variable length key and is optimized for a 32 bit processor. SEAL requires approximately five basic machine instructions per data byte. If the 160-bit key used has been pre-processed into the internal table, the computer with a 50 megahertz 486 CPU executes the SEAL code at a rate of 7.2 megabytes per second.

Microsoft reported the results of the encryption performance standard checker in its introduction to the CryptoAPI file. An application using Microsoft's CryptoAPI on a PC with a Pentium 120 megahertz CPU and Windows NT 4.0 operating system yielded the following results. _ In the Secure Digital Content Electronic Distribution System 100, each symmetric key and other small data fragments are encrypted using a public key. The public key algorithm uses two gold bars. These two gold losses are mathematically related, so data encrypted with one key can be decrypted with another key. The owner of the key will keep a key secret (private key) and publicly distribute it to the second Jin Yu (public key). To ensure the security of a confidential message that utilizes a public key algorithm, the recipient's public key must be used to encrypt the message. Only recipients with associated secret keys can decrypt the message. Also use the public O:\85\85156 to split the .D0C -35- 1255443 Golden Wheel > Fuss method to generate a digital signature. Secret Jin Yu is used for this purpose. The next section will provide information about digital signatures. The most common public key algorithm is the RSA public key cipher. The RSA public key cipher has become the de facto standard for public keys in the industry. Other algorithms that are also very useful in encryption and digital signatures include ElGamal and Rabin. RS A is a variable with a variable key length. Symmetric keying algorithms are much faster than public keying algorithms. In software, the speed of DES is roughly 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 megahertz Pentium CPU, the RSA Data Security Utility Kit B SAFE 3.0 has the following generations in secret key operations (encryption or decryption using secret keys) Rate: 216 kilobits per second at 512-bit modulus and 7.4 kilobits per second at 1024-bit modulus. C. Digital Signature In the Shiwang Digital Valley Electronic Distribution System, the issuer of SC(s) is digitally signed on the SC(s) to protect the integrity of sC(s). In general, in order to generate a digital signature for a message, a message owner first calculates a message digest (described below) and then encrypts the message digest using the owner's secret key. The message is delivered along with its signature. Any recipient of the message may first decrypt the signature using the public key of the owner of the message to recover the message digest and verify the digital signature. The recipient then calculates a summary of the received message and compares the summary to the recovered summary. If the message has not been changed during the delivery process, the calculated summary must be the same as the recovered summary. O:\85\85156 Split.DOC -36- 1255443 In the secure digital content electronic distribution system 100, since Sc(s) contains several data parts, a summary is calculated for each part, and A summary of the summary is calculated. The summary is encrypted using the secret of the sender of the Sc(s). The encrypted summary summary is the sender's SC(s) digital signature. Each part summary and the digital signature are included in the ontology of SC(s). The recipient of sc(s) verifies the integrity of the SC(s) and its components using the received digital signature and the summary of the score. A message summary is computed using a one-way hash algorithm. A hash algorithm takes a variable length input message and converts the input message into a fixed length string, i.e., a message digest. A one-way hash algorithm operates in only one direction. That is, it is easy to calculate a summary of an input message, but it is very difficult (calculatingly infeasible) to generate a good interest from its abstract. Because of the nature of the scramble function, we can treat a message digest as the fingerprint of the message. The most common one-way mess function is MD5 from RS A data security and SHA designed by the National Institute of Technology and Standards (NITS). D. Digital Certificate A digital certificate is used to prove or verify the identity of a person or entity that has transmitted a digitally signed message. A certificate is a digital file issued by a certificate authority (certificati〇n auth〇rity) that combines a public key with a person or entity. The certificate includes the public key, the name of the person or entity, the due date, the name of the certificate authority, and other information. The certificate also contains the digital signature of the certificate authority. O:\85\85 丨56 Division.D0C -37- 1255443 When an entity (or person) transmits a message signed with its public key accompanied by its digital certificate, the recipient of the message uses the certificate from The entity name of the book determines whether or not to accept the message. In the secure digital content electronic distribution system 100, each SC(s) other than that issued by the end user device 109 contains a certificate of the producer of the SC(s). Since many end users do not need to obtain a certificate or hold a certificate issued by a non-authentic certificate authority, 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 clearinghouse 105 may elect 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. SC(s) Graphical Representation Guide This document uses diagrams to represent SC(s) graphically, showing the encrypted portion, the non-encrypted portion, the encrypted key, and the certificate. Referring now to Figure 2, an illustration of an example of SC(s) 200 is shown. The following symbols are for the illustration of SC(s). The key 201 is a public key or a secret key. The perforation of the key such as the clearing house CLRNGH indicates the owner of the key. The PB in the key indicates that the key is a public key, and thus the key 201 is a public key of a clearing house. The PV in the key indicates that the key is a secret key. The diamond is an end user digital signature 202. The first word indicates that the secret key is used to generate the signature, and thus the EU indicates the digital signature of the end user as shown in the following table. A symmetric key 203 is used to encrypt the content. An encrypted symmetric keying element 204 contains a symmetric key 203 encrypted with a CLBGH PB. Rectangular O:\85\85156 Split.DOC -38- 1255443 The key at the top of the shape is the key used to encrypt the object. The symbol or text # within the rectangle indicates that the encrypted object (in this case, a symmetric gold residue) solidly shows another gold-added object, which in this example is a cross-identification code-encrypted object 205 . The conditions for the use of content authorization management are 〇6, which will be explained below. The SC(S) 200 includes a number of usage conditions 2〇6 signed by a final user digital signature 202, a transaction identifier encryption object, an application identification code encryption object 207, and an encrypted symmetric key object 2〇4.广 has 出 用来 用来 识别 识别 识别 识别 识别 识别 识别 识别 识别 识别 识别 用来 用来 识别 用来 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ CH Clearing House 105 CA Certification Center (not shown) F. — Secure Container Object Encryption Example The following table and figure provide an overview of the encryption and decryption procedures used to generate information and obtain information from Sc(s).

The program includes the steps shown in Figure 3 for the encryption procedure. The flow of the encryption program shown in Figure 3 Step 3 Program The sender generates a random symmetric key and uses the symmetric Jin Yu O:\85\85156 to split the DOC -39· 1255443 to encrypt the content. 3 02 The sender uses a messy algorithm to execute the encrypted content in order to generate a content summary. 303 The sender encrypts the symmetric key using the recipient's public key. PB RECPNT means the public key of the recipient. The 304 transmitter performs the encrypted symmetric key using the same hash algorithm used by step 302 to generate a symmetric key digest. 3 05 The sender performs the sequence of the content summary and the symmetric key digest using the same hash algorithm used in step 302 to generate the SC(s) digest. 3 06 The sender encrypts the SC(s) digest with the sender's secret key to generate the digital signature of the SC(s). Pv SENDER means the sender's secret gold loss. The 307B sender generates an SC(s) file containing the encrypted content, the encrypted symmetric key, the content digest, the symmetric key digest, the sender's certificate, and the SC(s) signature. The 307A transmitter must obtain a certificate from a certification center before starting a secure communication. The certificate authority includes the sender's public key and the sender's name in the certificate, and the brigade signs the certificate. PV CAUTHR means the secret key of the certificate authority. The transmitter transmits the SC(s) to the recipient. Flow of the decryption program shown in Fig. 4 Procedure 408 The receiver receives the SC(s) and prepares its components. O:\85\85156 Split.DOC -40- 1255443 409 410 411 412 413 414 415 The recipient uses the public key of the certificate authority to decrypt the digital signature in the sender's certificate and verify the digital signature. If the digital signature of the certificate is valid, the recipient obtains the sender's public key from the certificate. The recipient decrypts the Sc(s) digit signature using the sender's public key. Thus the SC(s) summary is restored. PB SENDER means the public key of the sender. The receiver performs the sequence of the received content digest and the encrypted key digest using the same hash algorithm used by the transmitter to calculate the Sc(s) digest. The recipient compares the calculated SC(s) digest with the SC(s) digest recovered from the sender's digital signature. If the two are the same, the recipient confirms that the received digest has not been altered and continues the decryption process. If the two are different, the recipient discards the 叱 (4) and notifies the sender. The recipient performs the encrypted symmetric key using the same hash algorithm used in step 411 to calculate the symmetric key digest. The recipient compares the calculated symmetric key digest with the symmetric key digest received in the sc(s). If the two are the same, the symmetry key of the recipient = plus 6, is not changed. The receiver continues to enter the private order. If the two are different, the recipient discards the SC(s) and notifies the sender. The recipient uses the same hash algorithm used in the process to execute the encrypted content in order to calculate the content summary. 〇Λ85\85156 Split.〇〇< -41 - 1255443 416 The recipient compares the calculated content summary with the content summary received in the sc(4).

The secret of Jin Hai’s recipient, Jin Yu, reconciles the encryption to the mountain and thus restores the symmetric key. Pv RECPNT means the recipient's secret key. 418 #收者 decrypts the encrypted content using a symmetric key, thus restoring the content. ΙΠ·Safe Digital Content Electronic Distribution System Process The secure digital content electronic distribution system (10) contains several components used by different participants of the system. These participants include a content provider 1 electronic digital content store 103, an end user via the end user device 1〇9, and a clearing house 1〇5. A high level system flow is used as an overview of the secure digital content electronic distribution system 100. As the content flows through system 100, the process outlined below tracks the content. In addition, the process outlines the steps used by each participant to make a purchase transaction, thereby decrypting and using the content 113. Some of the assumptions made by the system flow include: This is the system flow for a digital content service (a peer-to-peer interface for a human computer). The content provider 101 transmits the audio digital guest in a PCM uncompressed format (exemplified by music audio). The content provider 101 has an intermediary resource O:\85\85156 splitting .DOC -42· 1255443 in an ODBC-compliant database, or the content provider 1〇1 directly inputs the data into the content information processing subsystem, or Provide information in the specified ASCII file format. The electronic digital content store performs financial settlement. Content 113 is placed on a single hosted content website ηι. Those skilled in the art will appreciate that these assumptions can be changed to accommodate the precise nature of digital content such as 曰木詋, and programs, as well as electronic distribution system broadcasts. The following process is shown in Figure 1. Step 121 Procedure 121 The present donor 101 provides an uncompressed PCM audio file as the content 113. Entering the file name of the audio file together with the unique identification code of the internal user 113 of the content provider 101 into the workflow management program 1 5 4 〇 122 The inner valley information processing subsystem utilizes the content 113 of the content provider 101 < unique identification code, and The database maps the information provided by the template, and the media data is obtained from the content provider's database 160. The content provider 101 utilizes the work mud management tool program 154 to guide the content flow throughout the acquisition and preparation process. The content of the content 113 is input to the content information processing subsystem, and the above steps can be performed manually or automatically. This information includes copy restriction rules and any other business rules that are required. All media data entry can occur simultaneously with the audio processing of the data. 125 use the watermark tool to hide the data in the content U3, and

O:\85\85 丨 56 Split.DOC -43- 1255443 The content provider 101 must use the watermarking tool program to identify the m content. The watermark data may be included regardless of where the content comes from (in this case, the content provider 101), and regardless of any other information specified by the content provider 101. Each processing tool program 125 performs equalization, dynamic range adjustment, and resampling required by the content 丨13 for the different compression levels supported. Content 113 is compressed by the content processing utility 125 into the level of compression performed. The content 1 1 3 can then be played to verify that the compression produces the desired content 1 1 3 quality level. When necessary, equalization, dynamic range adjustment, compression, and playback quality check can be performed as many times as needed. The sc encapsulation utility encrypts the content 113 and a portion of the mediation data using a symmetric key. The utility then encrypts the key using the public key of the clearinghouse 1 〇 5 to produce an encrypted symmetric key. In the case of security material that does not contain content 113, the key can be transferred to any location because the only entity that can decrypt the key is clearing house 105. The 126 SC Encapsulation Tool 丨52 then encapsulates the encrypted symmetric key, mediation data, and other information related to the content 113 in an intermediary material SC. 127 Then encapsulate the encrypted content 113 and the mediation data into a content Sc. At this time, % became the processing of the content 1丨3 and the intermediary materials.

The content distribution tool program transfers the content SC(s) to the hosted content website 111. The escrow content website may be located in a special place dedicated to the content provider 1, the clearing house 105, or the escrow content website. The website's website address is the intermediary material that was added to the intermediary material sc. The content promotion website 156 will notify the electronic digital content store 103 of the new content 113 added to the system. The private digital content store 1 〇 3 then uses the content acquisition tool to download the intermediary material SCs corresponding to the content 丨丨 3 that it wants to sell. The electronic digital content store 1-3 will use the content acquisition tool to extract any material from the intermediary material SC(s) that it wishes to promote content 113 on its website. These Shaoxing points for accessing the mediation data can be secure and charged when necessary. The content acquisition tool program is used to input the content 113 usage conditions specific to the electronic digital content store 103. These usage conditions include retail price and copy/play restrictions at different levels of compression of content 113. The sc encapsulation tool program encapsulates the use condition of the electronic digital content store ι〇3 and the original intermediary material SC(s) into a quote SC. After updating the electronic digital content store 103, the final user of the Internet can purchase the content 113.

The end user playback application 195 will wake up based on the download time requested by the end user and create an order SC containing information such as the addition, symmetry key, transaction identifier, and end user information of the content ,13. Start downloading the program. The order SC is then transferred to the clearing house 105 for processing. The clearing house 105 receives the order SC, opens the order SC, and verifies that the data has not been tampered with. The clearing house i 05 confirms the end user _ purchase conditions of use. These conditions of use must conform to the conditions of use specified by Content Provider 101. The information is then recorded in a database. Once all the checks have been completed, the encrypted symmetric key is decrypted using the secret key of the clearinghouse 1-5. The symmetric key is then encrypted using the public key of the end user. The new encryption symmetric key is then privately encapsulated into a license SC using the SC encapsulation tool. The license then transmits the license SC to the end user. When the end user device 109 receives the license 80, the license SC is stored in the memory until the content SC is downloaded. The end user device 1G9 requests the hosted content website m to transmit the purchased content 113 corresponding to the license SC. The guest 113 is transmitted to the end user device 1G9. Upon receiving O:\85\85156 splitting .DOC -47 - 1255443 content 113, the end user device 1〇9 decrypts the content 113 using the symmetric key. IV. Rights Management Architecture Model A-Architecture Layer Function Figure 5 is a block diagram of the rights management architecture of the secure digital content electronic distribution system. Architecturally, there are four layers representing the secure digital content electronic distribution system 100: the license control layer 5 (H, the content identification layer 5〇3, the content usage control layer 505, and the content formatting layer 5〇7. In this section The overall functional objectives of each layer, as well as the individual main functions of each layer, will be explained. The function of each layer is completely independent of the functions of other layers. Within the broad limits, similar functions can be replaced by similar functions. It does not affect the functions of other layers. The output of one layer obviously needs to meet the acceptable format and semantics of the adjacent layer. The license control layer 501 ensures that the digital content is not illegally intercepted and tampered with during the delivery process; From a legitimate content owner and distributed via an authorized distributor (eg electronic digital content store 丨〇 3); digital content buyers have an appropriately authorized application; content is obtained at the purchaser or end user丨A copy of 丨3 says 'The buyer pays the distributor first; and keeps a transaction record for the return. Content identification layer 503 can verify the identity of the copyright and content purchaser. The copyright information of the guest and the identity of the content purchaser can track the source of any authorized or unauthorized copy of the content 113. Therefore, the content

The inner valley usage control layer 505 ensures that the copy of the content 113 is for the purchaser's device in accordance with the store usage component 519. The store usage condition 519 can specify the number of playbacks and local copy times for each 113, and can specify whether the content 113 can be recorded to an external portable device. The content in the content control layer 505 tracks the copy/play use of the content and updates the copy/play status. The content formatting layer 507 can convert the format of the content 113 from the native representation in the content owner's facility to a form consistent with the service specific functions and delivery devices of the secure digital content electronic distribution system 100. The conversion process can include compression coding and its associated pre-processing, such as frequency 2 and amplitude dynamic range adjustment. For the content 113 that is audio, on the purchaser side, the received content 113 also needs to be processed in order to obtain a format suitable for playback or to be transmitted to a portable device.

The content n 3 is stored in a compressed form in the end user device 109' in order to reduce the storage capacity requirement. The content j J 3 is decompressed during actual playback. It is easy to perform decoding when actually playing. The contents and types of encoding will be explained when the control layer 505 is used. 2. Content Usage Control Layer 505 The content usage control layer 505 allows specification and enforcement of the applied conditions or restrictions on the content 113 on the end user device i 〇9. These conditions may dictate the number of times the content 113 is allowed to be played, whether the subsequent copy of the content ι 3 is allowed, the number of subsequent copies, and whether the content ι 3 can be copied to the external device. The content provider sets the allowable use condition 517 and transmits the use condition 517 in the form of a % (see the section discussing the license control layer 5〇1) to the electronic digital content store ι〇3. The electronic digital content store 1G3 can add or reduce the use condition 517 as long as the use condition does not invalidate the original condition set by the content provider (8). The electronic digital content store (8) then passes (one (four)) all of the store usage conditions 519 to the end user device (10) and the clearing house (9). The clearing house (8) authorizes the release of the content 113 to the end user device (10) use condition confirmation 521. First, the content use control layer 5〇5 in the user device 109 executes the content use “enforcement of the piece 517.

The playback application 195 then encodes the content 113 in a cryptographic manner prior to storing the content 113 in the end user device 1〇9. The play application 195 generates a code key for each item, encrypts the key, and hides the key in the end user device 丨〇9. Then, whenever the end user device 109 accesses the content 1 13 for copying or playback, the end user device 109 verifies the copy/play code before allowing the content 113 to be decoded and performing playback or copying. The end user device 1〇9 also appropriately updates the copy/play code in any new subsequent copies in the original copy of the content n3. The copy/play encoding is performed on the already compressed content 113. That is, it is not necessary to first decompress the content 1丨3 before embedding the copy/play code. The end user device 109 embeds the copy/play code in the content 113 using a license watermark 527. Only the end user playback application 195, which recognizes the embedded algorithm and associated coded key, can read or modify the embedded data. The reader cannot see or hear the information; that is, the haibei material does not cause a perceptible decrease in the quality of the inner valley 113. Since the watermarking has undergone several steps of content processing, data compression, digital to analog and analog to digital conversion, and reduced signal quality introduced by normal content processing, 'the watermark is still in any representation including analogy. Reserved in content 113. In an alternate embodiment, the copy/play code is not embedded in the content 113 using an authorization license watermark 527, and the end user playback application 195 instead uses the secure storage usage condition 5丨9. 3 · Each identification layer 5 〇 3 is part of the content recognition layer 503, and the content provider 1 〇 1 also uses one

Upon arrival of the content Sc(s) 63 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 transaction data 642 to the other layers for proceeding. The license watermark embedding, copy/play encoding, out-of-order encoding, and further content processing are described with reference to FIG. Finally, in step 610, the clearinghouse 1-5 periodically transmits the summary transaction report to the content provider 101 and the electronic digital content store 1-3 for auditing and tracking purposes. V·Safety Container Object Structure A·General Structure Safety Container Object (SC) is a structure consisting of several components that together define a unit of content 113, or a part of a transaction, these components Information such as usage conditions, intermediary data, and encryption methods are also defined. SC(s) is designed to enable the integrity, completeness, and trustworthiness of information to be verified. Some of the information in SC(s) can be encrypted so that it can be accessed only after obtaining the appropriate authorization. SC(s) comprises at least one material table (Bin 〇f Materials; bqm for short), the component having an information record related to SC(s) and related to each component included in SC(s) Information record. For each component, a message extracting 85\85156 segmentation is performed using a hash algorithm such as MD-5, etc. D0C -57 - 1255443 is to 'and then the message digest is included in the BOM record of the component. The digests of the components are concatenated, and the digest is used to calculate another digest, and then the other digest is encrypted using the secret key of the entity that generated the SC(s) to generate a digital signature. The parties receiving the 8 (:(3) may use the digital signature to verify all digests and thus confirm the integrity and completeness of the Sc(s) and all of the components of the SC(s). The following information is used as a record in B〇M and a record of each component. The SC(s) type determines which records need to be included: SC(s) version SC(s) identification code SC(4) type (eg quote, order, transaction, content) , intermediary information or promotion, and licensing) SC(s) issuer generates SC(s) date SC(s) expiration 曰 clearing house's URL algorithm description of the digest algorithm (system pre-use for inclusion) Description of the variants of each component set to MD-5) (the system defaults to RSA)

The electronic digital content store 103 interprets the usage conditions 517 in the intermediary material sc(s) 62 and uses the information to provide an option for which it wishes to quote its customers, and uses the information to add retail information for the content 113. After an end user selects a content 113 item to purchase, the end user device 1〇9 requests authorization based on the content 113 of the store usage condition 519. Before the clearing house 105 transmits a license sc(s) 660 to the end user, the clearinghouse 105 first verifies the store usage condition. The required condition 519 is consistent with the allowable use condition 517 specified by the content provider 101 in the intermediary data SC(s) 620. When an end user device 109 receives the purchased content 113, the store usage condition 5 19 is encoded into the content 113 using a watermarking tool program, or encoded into securely stored usage conditions 519. The end user playback application 195 executing on the end user device 109 ensures that the store usage condition 5丨9 encoded to the content 113 is enforced. The following are some examples of store usage conditions 5 1 9 in an embodiment where content 113 is music: O:\85\85156 Split.DOC -60- 1255443 The song can be recorded.

Security Container Object Flow and Processing Overview The content provider 101 creates an intermediary material Sc(s) 62〇 and uses the intermediary material SC(s) 620 to define content 113 such as songs. The content 113 itself is not included in these SC(s) because the capacity of the content 113 is generally too large for the electronic digital content store 1〇3 and the end user, and cannot be used only for accessing descriptive mediation data. Efficiently download container objects. Instead, sc(s) contains an external generic resource locator (URL) that points to content 113. SC(s) also includes: mediation information providing descriptive information related to the inner table 113, and digital audio segments in the case of a CD cover picture and/or in the case of a song content I] Any other related information. The electronic digital content store 103 downloads its authorized intermediary material SC(s) 620 and creates a quote SC(s) 641. In summary, the offer sc(s) 641 contains certain components from the intermediary material SC(s) 620 and the bom, as well as additional information added by the electronic digital content store 103. When the offer sc(s) 641 is established, a new BOM of the offer SC(s) 641 is generated. The electronic digital content store 103 also uses the intermediary material SC(s) 620 to extract mediation information from these mediation materials, and creates an HTML webpage on its website for providing the description of the content 丨i 3 to the end user, thus ultimately using It is possible to purchase content 113. The information added by the electronic digital content store 103 in the quotation SC(s) 641 is usually used to narrow down the selection condition 517 O:\85\85156 division specified in the intermediary material SC(s) 620.

One of the clearing houses 1 〇 5 The function is to decrypt the watermark instruction from the quote SC(s) 641 and decrypt the symmetric key 623 required to decrypt the content 113 from the content sc(s) 630. An encrypted symmetric key 85\85156 is harmful to IJ. DOC - 62 - 1255443 The key 623 records a symmetric key 623 that actually contains more than one actual encryption. Before performing the encryption, the content provider 101 may first choose to append its name after the actual symmetric key 623. The content provider When the name of ι〇1 is encrypted together with the symmetric key 623, the counterfeit content provider 101 can be used to establish its own intermediary material Sc(s) 620 and content SC(s) 630 in a secure SC(s). Clearing house 105 verification along with symmetric key 623 The encrypted content is the name of the content provider 1 in the SC(s) certificate. If the clearing house 105 needs to make any changes to the watermark instruction, the clearing house 105 decrypts the symmetric key 623. Then, the watermarking instructions are modified, and the watermarking instructions are again encrypted using a new symmetric gold balance 623. The symmetric key 623 is then re-encrypted using the public key 661 of the end user device 109. The clearing house 1〇5 The other symmetric golden 623 in SC(s) is decrypted' and the symmetric key 623 is again encrypted using the public key 661 of the end user device 109.

The end user play application 195 decrypts the content 113, the mediation material, and/or the watermark instruction using the symmetric key 623 from the license SC (4) 660. The watermark instructions are then appended to the content 113' and the content 113 is out-of-order encoded, and the encoded content (1) is stored in the end user device 109. D. Intermediary data security container object 62〇 format The following table shows the components included in the mediation material sc(s) 62G. Each of the columns in the 4 Parts row is a separate object in sc(s) with B〇M (except for the part name enclosed by the gate character). A record of one of each component included in SC(s) is stored. The Pan Exists line indicates that the component itself is actually contained in SC(s) and the Digest line indicates whether a message digest is calculated for the component. When an SC(s) system is included in other SC(4) (as determined by the associated template), some components will not propagate, but the entire original B〇M will propagate. Since the clearing house 1G5 requires the entire BQM to verify the digital signature in the original SC(s), the above steps are performed. The key description section of the table below defines the A records for each packet in the key description section of sc(4). The record in the key description section defines the beneficiary associated with the encryption key and the algorithm used to encrypt the components within Sc(s) or to encrypt the components within another sc(s). Each record contains the encrypted component name and, if necessary, a URL to another SC(s) containing the encrypted component.

O:\85\85156 Split.DOC -77- 1255443 method. An API implementation is used to create an SC(s) encapsulation API that accepts the following parameters as input: a tool interface, and one of the buffers of the sequential structure; an instruction is a command to the encapsulation utility News. The encapsulation tool program command includes the SC(s), an associated BOM record, and the addition of the record to the key description portion. Each node in the buffer and the component SHA required to execute the command are added to the name and location of the BOM component having a value added to the BOM, indicating the number of serial structures included in the buffer.

Each bit is 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 the structures in the buffer have been processed. When building a SC(s), combining the components into a single object is the final step. - Indicates whether the digital signature is omitted in the BOM section. If the flag is not set, the digital signature is first calculated before the Sc(s) is combined into a single object. In an alternate embodiment, several APIs execute an encapsulation tooling interface for creating - Sc(s), and the APIs accept the following parameters as input: first call an API to generate a bill of materials (BOM) portion, The method is to transmit an indicator of a structure, and the structure contains some information for setting the starting value of Sc(s), which includes the scribble in the section of Sc(s) 3

The end user device 109 first checks the digital certificate revocation list, and then uses the public key 621 of the clearing house 105 to verify the information in the digital certificate of the electronic digital content store 1〇3, and verifies the electronic digital content store 1〇3 It is one of the effective distributors of the content 113 on the electronic distribution system in the secure digital. The clearing list of the 105-dimensional digital certificate of the clearing house. The abolition list may be included in a license %(4)66〇 generated by the clearing house 105 as an integral part of the sc(s). The end user device 1〇9 retains an abolition list, O:\85\85156 split. DOC -86-1255443 and thus the abolition list can be utilized as part of the confirmation of the electronic digital content store 1〇3 digital certificate. When the end user device 109 receives an authorization SC(s) 660, it determines whether the SC(s) contains a new revocation list, and if so, updates the end user device 丨〇9. A list of abolitions of machine storage. B. Rights management program quotation SC(s) analysis: After the end user receives the transaction sc(s) 64 containing the quotation SC(s) 641 from the electronic digital content store 1 〇 3, the clearing house 1〇5 from the final The user receives an order SC(s) 650. The order SC(s) 050 includes: a plurality of components including information related to each 113 and its use, information related to the electronic content store 1 〇 3 of the sales content 1 ^ 3, and the purchase content 丨j 3 Information about the end user. Before the clearing house 105 begins processing the information in the order Sc(s) 650, the clearinghouse 1-5 executes certain procedures to ensure that the SC(s) is actually valid and has not tampering with the sc in any way. ) The information contained. Acknowledging that the clearing house 105 verifies the digital signature and begins the confirmation of the order sc(s) 650, the clearing house 105 then verifies the integrity of the components of the order SC(s) 650. In order to confirm the digital signature, in the case of a signature, the clearinghouse 1-5 first decrypts the content 63 1 of the signature itself using the public key 661 of the included signed entity. (The signing entity may be a content provider, an electronic digital guest store 103, an end user device 1〇9, or any combination of the above components.) The clearing house 105 then calculates each of the SC(s) The sequence component extract 85\85156 splits .D0C -87 - 1255443 to < summary, and compares the calculated summary with the decrypted inner valley 113 of the digital signature. If the two values match, the digital signature is valid. To verify the integrity of each component, the clearinghouse 1-5 calculates a summary of the component and compares the calculated summary to the digit value in B〇M. The clearing house 105 follows the same procedure to verify the intermediary information contained in the order Sc(s) 65 and the digital signature of the quoted Sc(s) 641 part and the integrity of the composition. The parental and quotation SC(s) 641 digital signature verification procedure is also indirectly verified from the store number 1 in the pen number for the secure digital content electronic distribution system 100. The above procedure is based on the clearing house 105 being the issuer of the certificate. In addition, the clearing house 105 can also successfully verify the digital signature of the transaction SC(s) 640 and the quote SC(s) 641 by using the public digital Yu of the electronic digital content store ,3, but only after signing the Sc(s) This can only be done if the entity has ownership of the associated secret key. Please note that the clearing house 丨〇5 does not require a local database of the electronic digital content store 1-3, because the store uses the clearing house's public key to sign the transaction Sc(s) 640 and quote SC(s) 641 public key. The clearinghouse 105 then confirms the store usage condition 519 of the content n 3 purchased by the end user to ensure that the store usage condition 519 is included within the limits set in the intermediary material SC(s) 620. As described above, the intermediary material SC(s) 620 is included in the order sc(s) 650. The key processing successfully completes the trustworthiness and integrity check of the order SC(s) 650, the confirmation of each store 1 〇3 in the dice digit, and the store usage condition 5 19 〇:\85\85丨56 segmentation After the confirmation of .DOC -88 - 1255443, the clearinghouse 1〇5 performs the processing of the encrypted symmetric key 623 and the watermark instruction. The intermediate information Sc(s) of the order SC(S) 650 has a plurality of symmetric keys 623' and the symmetric keys 623 are located in the key description portion encrypted by the public key 621 of the clearing house 105. When the intermediary material SC(S) 620 is generated, the content provider 101 performs encryption of the symmetric key 623. A symmetric key 623 is used to decrypt the watermark instructions, and other symmetric keys are used to decrypt the content 113 and any encrypted mediation data. Content 113 can represent a single-song song or all songs on a -CD, so a different symmetric key 623 can be used for each song. The watermarking instruction is contained in the intermediate material SC(4) 62〇 portion of the order SC(S) 650. The content ιΐ3 and the encrypted mediation data are stored in the content (4) 630 on the hosted content website lu. The encrypted content 113 in the content SC(s) 630 and the website and component names of the intermediate data portion are included in the key description portion of the intermediary information SC(s) 620 of the order 叱(4)65〇. The clearinghouse 1-5 decrypts the symmetric key 623 using its secret key and then encrypts each of the symmetric keys using the public key 661 of the end user device 1〇9. The public key 66i of the end user device (10) is extended from the order sc^ 650. The newly encrypted symmetric key 623 is included in the key description portion of the license SC(s) 660 that is sent back to the end user device at the clearinghouse 1-5. During the processing of the symmetric key 623, the clearinghouse 1〇5 may want to modify the watermarking instructions. If this happens, the watermark instruction will be modified and re-encrypted after the clearing house 105 will decrypt the name Jinyu 623. The new / pre-watermark command is included in the authorization to transmit back to the end user device (10)

End user device! 09Using the license Sc(s) 66〇 information downloading the guest SC(s) 630, and accessing the encrypted content n3 and the intermediary data. Finally, the user device 109 also executes a watermarking instruction. If the clearing house 105 cannot successfully process the order sC(s) 650, an HTML web page is sent back to the end user device 丨〇9 and the HTML web page is displayed in the internet browser window. The HTML page indicates why the clearinghouse 105 is unable to process the transaction. In an alternate embodiment, if the user has purchased a copy of the content 113 prior to the release date set by the content 丨13 sale, a license is issued that does not have the symmetric key 623 Sc(s) 66 Hey. On the issue date or after the issue date, the license Sc(s) 66〇 is transmitted back to the clearing house ι〇5 to receive the symmetric key 623. For example, the content provider ι〇ι allows the user to download the first new song before the release of the first new song, and the user can download the song before the release date set by the inner provider 101, and prepare Play the song well. In this way, the content (1) can be immediately issued on the issue date, and the eyebrows are troubled by the bandwidth and download time on the issue date. C. The country-specific parameter database 105 may choose to use the domain name (or privilege) of the end user device 109 to determine the end user's country 4 if the end user resides.

In the case of the financial settlement in which the clearing house 105 processes the content 113 purchase, the electronic digital content store 1-3 adds a flag to the transaction Sc(s) 64, and the flag is carried in the order sc 650 and transmitted to Clearing house 1〇5. The clearing house 105 interprets the flag in the order Sc(s) 65〇 and continues the transaction without charging the end user for the purchase of the content 113. VIII·Content Provider A. Overview The electronic distribution system in the prince digital 1 内容 The content provider 1 〇 1 is the digital content owner or the entity that owns the content i i 3 . The task of the content provider 101 is to prepare the content 113 for distribution, and to enable the electronic content store 103 or the retailer 113 of the downloadable version to obtain the <BeiXun related to the content 113. In order to provide the most secure security and rights control to the content provider 101, a series of tools are provided to enable the content provider 1.1 to prepare its content 113 at its premises and securely encapsulate its content 113. To SC(s), thus when the content 113 leaves the realm of the content provider 1.1, the hidden content 113 is secure and the unauthorized person cannot access or access the content 113. This way the content 丨丨3 can be freely distributed via a non-discrete network such as the Internet without fear that the hacker or unauthorized person will steal the content 113. The ultimate goal of the content provider 101's utility program is to prepare a content 113 such as a song or series of songs and enclose the content 113 to O:\85\85156 partition. DOC -96 - 1255443 content SC(s 630, and the information describing the song, the approved usage of the song (content usage condition 517), and the promotional information of the song are encapsulated into an intermediary material SC(s) 620. To achieve this, a set of tools is provided: Workflow Management Program 154 - Schedules the time of the event and manages the synchronization required for each program. The content processing tool 155 - for controlling content including the addition of a watermark, pre-processing (in the case of an audio, any necessary equalization, dynamic range #1 integer, or resampling), encoding, and compression 1 1 3 files prepare a set of tools. The mediation data assimilation and input tool program 161_ uses the database 160 and/or the third party's database or data input file collection content 113 from the content provider to describe the information and/or collect the information via operator interaction and A set of tools for specifying content usage conditions 5丨7 is provided. An interface for capturing or extracting digital audio content such as CDS or DDP files is also provided. A quality control tool can be used to preview the prepared content and mediation data. Any corrections required for the intermediary material, or resubmission of the content may be made for further processing. The SC(s) encapsulation utility 152 - encrypts and encapsulates all of the content 113 and information and calls the SC(s) encapsulation utility to encapsulate the content 113 and information into the SC(s).

B. Process Management Program The purpose of this utility program is to schedule, track, and manage the processing activities of Content 113. The application can be accessed by multiple users and can schedule and status the content 113 on the intranet of the content provider 1G1 or the remote location within the enterprise's external network (extranet). an examination. This design allows for collaborative processing where multiple individuals can work on multiple pieces of content 113 in parallel, and can assign specific responsibilities to different individuals, and these individuals can be distributed around the world. Referring now to Figure 8, the main program shown in the block diagram of the main program corresponding to the workflow management program 154 of Figure 7 summarizes the content (1) processing functions provided by the tool (4) described in this section. The workflow management process 54 is responsible for providing the materials (4) and, when completing their current procedures, directs the work to the next required program. The above steps are performed using a series of application interfaces (APIs), and each processing tool calls the application interfaces to perform the following: Capture the next work instruction to be processed successfully to complete a program indication. The successful completion of a program and the reason for the failure provides a transition state of the program (in order to start - some of the procedures that only need to be completed by a dependent program). The product workflow management program 154 that can be obtained by adding the annotation to a specified program also has a use. Interface, and an example O:\85\85156 split. DOC -98 - 1255443 Workflow Manager user interface 700 is shown in Figure 7, and the user interface provides the following functions: Specify and execute one of the system presets and conditions. The configuration settings control function allows the user to self-process the workflow and automate the process flow. The status query and report will add an associated work comment or instruction. One or more program work management (ie, suspend, release, remove, change priorities) Order)) Each program has a pass associated with it and managed by the workflow management tool program m. All programs requesting work from the workflow management program 154 will cause the workflow management program 154 to suspend the program (work #program) in a waiting state when the program is not working in the associated queue of the program' or The individual procedures associated with the job and performing the work are required: all information is returned to the program. If a program is suspended in a wait state, the program resumes processing when the workflow manager 154 places the work in the queue of the program. The workflow management program 154 also manages the flow or sequence of processing in accordance with the specifications specified by the group. If the content provider 1.1 has special processing requirements or wants to set a specific preset rule, the content provider 1〇1 can customize these rules. When the program report completes the work assigned to the program, the program notifies the workflow management program 154 of such status, and the workflow management program 154 decides which one to place the next job based on the specified rules: \85\85 〗 56 Split .DOC -99 - 1255443 in the queue.

Upon completion of any program, the workflow manager 154 checks the queue and determines if any work is waiting for the completion of the program (action), or information provided by the program. If this is the case, store the work in the appropriate program queue. 2. The new content requirement program 8〇2 内谷k ί,者1 〇1Determines which products they want to sell and distribute electronically (for example, a product can be – a song or a collection of songs). The initial function of the workflow management program 154 is to enable the operator to identify these products and place them in the queue of the new content requirement program 8〇2. The content provider UH can use the configuration settings option to specify which information is prompted on the product selection interface. Enter enough information to uniquely identify the product. You can also choose to include some additional blocks to manually enter the information needed to initiate the audio processing phase while the media data is being extracted. If it is not provided manually, you can choose to get the information from the configuration environment preset by the system, or expand the information from the content provider's database 16 and it is like the automatic mediation data acquisition program 8 In the case of 〇3, the information is obtained in the first stage of the intermediary data processing. The structure and capabilities of the content 113 in the content provider's database (10) determine the content selection process. If the necessary information required to perform the query to the database 16 of the content provider 1.1 is specified, the automatic mediation data acquisition program 8〇3 processes the work O:\85\85156 split. DOC -101 - 1255443 . In the music embodiment, the type of product, the desired compression level, and the P C Μ or W A V file name of the audio are specified for the time of the product to be arranged for audio processing. This information can be entered as part of the product selection process via a custom query interface or the World Wide Web browser function, or selected. The specification of the information allows the schedule of the product to be scheduled for content processing. The product selection user interface provides an option for the operator to specify that the product is to be released for processing, or to temporarily retain the product for further information input. If the product is retained, the work is added to the queue of the new content requirement program 802, while waiting for further action to complete the input of the data, and/or release the product for processing. Once the product is released, the workflow management program 154 evaluates the information specified and determines which programs the work is ready to transfer to. If the appropriate information is provided and the database 160 of the content provider 101 is automatically queried, the work is placed in the queue for the automatic mediation data = program 803. If the configuration of the database mapping table is not set for the automatic mediation data acquisition program rib 3, the work is placed in the queue for the manual mediation data input program 804 (see automatic mediation data acquisition procedure 803).

If the required general information for audio processing and the specific information required for adding the watermark are specified, then the jade is placed on the material-added watermark: Sequence _ the pass (the first stage of content processing) . If the required information is lost when the work is released, the work is placed in the queue of the product waiting action/information program together with the status indicating that the information was lost. , ΟΛ85\85156 split. D0C -102-1255443 If the status indicates that the file name of the content 113 is missing, for example, in the case where the content 113 is audio and the PCM or WAV file is missing 'this status may indicate that the content needs to be retrieved (or from the digital The media is digitally extracted). Audio Processing This requirement can be accessed by the file system interface. If the song is located on a structured system that the external media or audio processing tool cannot access purely, then the first (four) copy (four)-accessible building system is cut. If the song is in digital format but stored on a (3) or digital tape, the file system extracts the songs by the privately accessible file system. After accessing these handles, the workflow management user interface 7GG is used to index or select the path and file name of the king, so that all other information required for the watermarking program has been specified. , the side work can be released to join the watermark program. 3. Automatic mediation data acquisition program 8〇3 Automatic mediation data acquisition program 8G3 performs a series of queries on the content provider ι〇ι database 16〇 or the input data-stage database, try to automate The way to get the most product information you can get. Before the items can be placed in the automatic mediation data acquisition program 803 (4), the automatic mediation data acquisition program 8〇3 first requests the following information: a database mapping table having appropriate information for generating the content Provider 1 〇 1 〇 〇 查询 查询 执行 执行 执行 执行 执行 执行 执行 执行 执行 执行 执行 执行 执行 产品 产品 产品 产品 产品 产品 产品 产品 产品 产品 适当 适当 适当 适当 适当 适当 适当 适当 适当 适当 适当 适当 适当 适当 适当 适当 适当The information required for Content 113.

Adding a watermarking program 808 Adding a watermarking program 8〇8 adds copyright and other information to the content 113. In an embodiment where the content Π3 is a song, the utility requires the following information as input: song file name (multiple file names in the case of an album) watermark instruction watermark parameters (to be included in the watermark Information) When the watermarking program 8〇8 is completed, if the input required for the pre-processing and compression program 809 can be obtained, the work is placed in the queue of the pre-processing and compression program 809, otherwise the work is placed on the product. Waiting for the action/information program 801. 9. Pre-Processing and Compression Procedure 8〇9, Pre-Processing and Compression Procedure 809 encodes the content 113 into a specified compression level to perform any necessary pre-processing first. When a job is placed in the checklist, it actually produces multiple items. A job is generated for each compression level of the desired product. This encoding can be executed on multiple systems in parallel. The utility requires the following input: , , the name of the content to which the sub-watermark is added (in the case of an album, multiple

O:\85\85156 Split.DOC -106- 1255443 File name) Product quality level (this quality level can be preset) Compression algorithm (this compression algorithm can be preset) Product type (in case of preprocessor required) Next) When the encoding process is completed, if the workflow rules have been set, the work is placed in the content quality control program 81. If this is not the case, put these tasks in the queue of the encryption program. If the cooperating provider of the encoding tool program does not provide a method of displaying the percentage of content 113 that has been processed, such as audio, or does not provide a percentage of the entire selection indicating the selected content 113, < In the method, a coding rate for determining the content of the pre-processing and compression tool program for the digital content shown in FIG. 8 is shown in FIG. The method begins by selecting the desired encoding algorithm and bit transfer rate in step 1101. A query is then made in step 1102 to determine if the algorithm and encoding rate have a pre-calculated rate factor. The rate factor is a factor used to determine the rate at which a particular coding algorithm and a particular bit transmission rate are compressed. If no previously calculated rate factor is stored, the same version of the content 113 is encoded for a predetermined period of 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 Rnew for a predetermined period of time. In step 1108, a new rate factor RNEW is calculated as rnew = (encoded digital content length) / (time length) for a known length of time and the amount of content 113 encoded. In step 1109, the content 113 is encoded and the encoding state is displayed using a rate factor RNEW calculated by the first leaf. Then at the steps

〇Λ85\85156 Segmentation. DOC-107-1255443 1107 stores the coding rate factor Rnew for future use in the coding algorithm and coding bit transmission rate. In step 3, if the selected algorithm has a previously calculated rate factor Rstored, the content 11 is encoded in step 1 104 and the progress rate is plotted using the previously calculated rate factor Rstored. At the same time, an active rate factor Rcurrent is calculated in step 11〇5 for the selected algorithm and bit rate. In step 1106, the current rate factor 11(10)·r is used to update the average of the remaining and rate Q numbers RNEW. Rate factor

This repeated update makes the decision of the coding rate more and more accurate each time a specific coding algorithm and a bit rate are continuously used. The new rate Rnew is then stored in step 11G7 for future use. If the current rate factor Rcurrent exceeds a previously stored rate factor to a particular range or threshold, Rst〇red may not be updated. RED can be used to display the encoding status. The encoding status includes, at the current, flat code rate, based on the encoding rate, and the total file length of the content 113, = the percentage of the full-shortage content 113 is displayed as a percentage bar. The encoding status Γ Γ includes the remaining encoding time. By dividing the total file length of the content 113 by the code rate Rgurrent discarded, the remaining encoding time can be calculated. J transfers the encoding status to another process that may be used for the calling program. This type of program assists the supervisor in encoding and batching the dependent programs for more efficient processing. We understand that in a supportive example, the encoding can include the step of adding a watermark. 1〇's quality control procedures 8 10 Content quality control procedures 81〇 functionally similar to monitored transmissions

This program has no dependency on other programs except the addition of the watermarking program 808 and the pre-processing and compression of the encoding portion of the program 8()9. When the content quality control program (4) is completed, the following options are available: The work can be released and placed in the item list of the encryption program 811. Comments can be attached and one or more jobs can be relocated to the queue of pre-processing and compression programs 809. The last option requires that the unencoded but watermarked version of the song file remain in a usable state until after the content quality control program has been executed. 11. Encryption Procedure 811 The addition procedure 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 process is completed, the job is placed in the queue of the content SC(s) generation program 812. 12. The SC(s) generation program 812 within the content SC(s) generation program 812 may need to include certain intermediary material files in the content SC(s) 630. If files other than content n3 are needed, the files are collected and the SC(s) encapsulation process is called to generate a content sc(s) for each compression level of the generated content 113 (e.g., a song). . When Yu Yuancheng's content SC(s) generates the program 8 12, the song will be placed in the final quality assurance program 8丨3 according to the specified workflow rules: \85\85丨56 Split .D〇c -109- 1255443 Broadcast program 8 1 4 queue. 13 · Post-Quality Assurance Procedure 8 1 3 Final Quality Assurance Procedure 8 1 3 is an optional step to perform an interactive check between the associated intermediary material and the content SC(s) 630 to verify the above Match the two correctly and verify that all of the included Besun and Neigu 11 3 are correct. Yu Yucheng's final quality assurance program 8 1 3 o's put the work into the content distribution program $ 14. If a problem is found, in most cases the work will be put back into the queue of the shortcomings. The rework at this stage is much more costly because the product must undergo an entire re-encryption and re-encapsulation process in addition to the reprocessing required to correct the problem. We strongly recommend using the previous quality assurance phases to ensure the quality of the Content 113 and the correctness and completeness of the information. 14. Content Delivery Program 814 The Content Delivery Program 814 is responsible for transmitting the SC(s) to the appropriate hosting website. After the SC(s) is successfully transmitted, the work completion status is recorded and the job is deleted from the queue. If a problem occurs while transmitting sc(4), the job is flagged as a failure and an error in the workflow manager 154 after a specified number of retries. 15.

The inbound processing tool program content processing tool 155 is actually used to process digital content files to generate a set of software tools plus watermark @, encoded, and encrypted content. The tool utility utilizes industry standards. The digital content processing tool program's, when the technology is progressing, can be replaced by plug-in, watermarking, encoding, and encryption technology. If the system can be called via a command line system, the industry standard tool selected by the manned interface' And transfer the parameters to the child tool, or provide a toolkit that can call the function via a DLL interface, to automate the content processing to a considerable extent. A front-end application query processing content processing tool for each tool In program 155, if there is any next work available in the queue, and the required files and parameters are retrieved, then the industry standard content processing tool is loaded to perform the required functions. If the tool does not report a termination status, you may need to manually update the queue. A general version of the content processing tool 155 will now be described, but a version from the user is also possible. The content processing tool 155 can be written in Java, C/C++, or any equivalent software. Any computer-readable device such as a floppy disk or a processing tool 155 distributed through a website. 1 · Watermarking tool program

The content provider] and the specific watermarking technology determine the actual information to be written. The front-end floating water Ρ tool can obtain this information, so the watermarking tool program can be sent to the floating watermark function. In this way, the data assimilation and input tool procedures are only 1 A female, with synchronization requirements, in order to ensure that the intermediary = the same = and the input tool program 161 first obtain the information, and then allow the audio file of the song to be processed. . Before going to the song, the ^^(4) printing information will be the first step of the audio processing, because this step is the common step of all the encoding of the song. As long as the watermark can overcome the test of the coding technology, the port watermarking process ρ Μ 、, 4 mothers - lightly performing - times plus each of the f plus floating cutting techniques are well known and available on the market. However, it can also be used to float the H-cut m(4) quasi-tool. 2) Pre-processing and compression tool program, two: and the compression tool program allows the user to execute the I and the compression program. Audio coding involves two programs. The above is the implementation of the PCM audio stream (in the music content example) - the sound = algorithm. The encoder can typically be adjusted to produce various play bit stream transmission rates depending on the desired level'.

Therefore, each & 1 1 1 1 may provide a variety of digital content quality for downloading 'to meet the impatient and narrow-band network customers who do not want to spend hours waiting for download; Or customers who use broadband networks, which either buy high-quality content 113 or have a higher speed connection.

The compression algorithm has changed in its technology to produce a reproduction of the lower bit rate of the content. The technique can be changed by algorithm (ie MPEG, AC3 ATRAC) and binder level. In order to obtain a higher compression level, the data is usually resampled at the lowest sampling rate before the data is transferred to the compression algorithm. In order to obtain more efficient compression under the facsimile_loss less inert shape, or to avoid extreme signal loss in some frequency range, digital content may sometimes need to adjust the equalization level of certain frequencies. , or adjust the dynamic range of the recording. The content pre-processing requirements are directly related to the compression algorithm and the level of compression required. In some cases, the type of content U3 can be successfully utilized (e.g., as a basis for determining pre-processing requirements) because songs within the same _-type typically have similar dynamic ranges. Using a certain % solution When these pre-processing functions are part of the encoding program, when using other compression tools, the required pre-processing is performed before the compression is performed. In addition to the downloadable audio building for sale, each song is also have-

This coffee code is also the responsibility of the content processing program 155. The heart provider (8) provides the segment as an independent (four) job, or as a parameter of offset and length. As in the case of watermarking, we hope that the encoding tool can be loaded via the coffee or command line system call interface and all necessary parameters can be transferred to the encoding tools for pre-processing and compression. For example, if the content is music, and if it is decided to retrieve the type of the song from the content provider's database 160 prior to performing any audio processing, then the wide code utility and the intermediary data assimilation and input utility 161 may be required to be the same as above. The situation depends on the selected coding tool and the song type. If the content provider (9) changes the selection of each song, etc., the selection is also provided before the encoding step. Information, and the information is consistent with the mediation data and the mediation data generated by the input tool program i6i. Objective: Various high-quality code algorithms and tools are known. However, the front-end coding tool can support various industry standard codes. The utility model is the same as the multi-image 12'. The figure shows a flow chart of an embodiment of the automatic I, material transfer tool according to the present invention.

Then, in step 1202, the content provider ιοί's database 160 is searched using the identification code as an index. In step 12〇3, in the database 16 and any other related The resource retrieves all or part of the information required by the workflow management program shown in Figure 8. The information may include the content 113 and the intermediary material associated with the content 112. In step 204, the expanded additional is utilized. Information to start the workflow management program 54 to generate electronic content 11 3. We know that several selected media such as several CDs can be placed in the queue, so that the automatic mediation data acquisition tool can be generated. A series of content for electronic distribution. For example, all of the content 113 can be generated from a series of cds, or even one of a selected one or more CDs that can be viewed from the content provider 101. All of the content is generated in the song ι ΐ 3. In an alternative embodiment, the pre-processing parameters can be automatically retrieved from the content provider's database 16 . Referring now to Figure 13, an automatic setting is illustrated in accordance with the present invention. The method of pre-processing and compressing the parameters of the pre-processing and compression tool is shown in Fig. 8. In this embodiment, the content is music. In step 1301, the music to be encoded in the content processing tool 155 is selected (content 113). In step 1302, the type of the selected music is determined. The music type can be manually entered or other available mediation information such as additional information retrieved from the program shown in the figure can be used to determine the O:\85\85156 ·;>, φΐΌ0Γ 1255443; class; then check the selected audio compression level and the compression algorithm in step 1303. Then in step 13, the music type, the compression set value, and the compression algorithm Query which compression parameters should be used in the special, first processing and compression program 809. 3 · Content quality control tool program content quality control tool program allows users Enough to implement the internal quality control program 810 described above. The utility is an optional content processing tool' and allows the quality control technician to have the opportunity to re-examine the encoded and watermarked content and based on Quality metrics approve or reject such content. The quality control technician can re-encode the content and manually perform pre-processed adjustments until the appropriate quality is obtained' or mark the song's flag as needed Reprocess and attach a comment explaining the problem. The inner valley k provider 101 can set the program step as an optional step or a necessary step for the content processing workflow. In the case of encapsulating the content, there is SC (s) (for example - each of the songs on the CD (4)), after providing an optional final quality assurance program (1), the quality of the content encoding can be tested, but can be encrypted and Before the envelop, I found out that I had to ask for more efficient content processing. Therefore, it is highly desirable to also have the quality of the gamma in this step, rather than waiting until the end to complete all the processing. 4. Encryption Tool The encryption tool allows the user to perform the last step of the encryption process 11 described above.

The encryption utility is a function of the Sc(s) encapsulation utility. Call the child SC(s) encapsulation utility to encrypt the song and return the resulting encryption. The key is then placed in the SC(S) encapsulation utility for use in generating the intermediary material SC(s) 620. E. Content SC(s) Generation Tool Once the mediation data has been collected, the content SC(s) generation tool program divides the mediation data into several types according to the intended use of the intermediary material. The mediation data of these groups is written into the archive, and is placed in the sc-encapsulation tool program as the mediation data portion of the mediation material SC(s) 620. Each component (file) has unique processing requirements. Once the associated song is processed and encrypted, and the destination (the web address hosting the content website lu) is determined, the content SC(s) 630 of each 113 is generated. The content 113 that has been processed and meets all of the foregoing requirements is queued in the queue for inclusion in the queue of the package utility of the workflow manager 154. The content SC(s) generation tool now retrieves all necessary files generated by the mediation data assimilation and inputting the previous steps of the tool 161 and calls to generate the intermediary material SC(s) 620.

Once all the SC(s) have been created for the content structure, the final quality assurance check can be performed on the content. The quality yarn can be executed at each stage of the content 113 preparation program. The content provider 1〇1 can choose to perform quality assurance when completing each major step to avoid future work, or can choose to wait until all the audio preparation procedures are completed, and immediately perform quality assurance for each item. If the latter is selected, quality assurance is performed at the point in time when SC(s) generation is completed. The utility can open, check, and play music for each SC (4) of the first song. When any problem is found, even a small text change requires re-establishing the Sc(s)e4 due to sc's internal security features to avoid unnecessary reprocessing time. We strongly recommend using intermediate quality assurance steps. To ensure the accuracy of the mediation data, we also recommend to reserve this specific quality assurance step to confirm the cross-reference between each Sc(s) of the song. If a problem is found, the quality assurance personnel can enter an additional A description of the problem to the song and re-posting the child's song to the appropriate processing queue for reprocessing. The status is updated appropriately in the workflow manager 154 to indicate all relevant components of the song. Status. If no problem is found, the content 113 is marked as ready for distribution. G. Content Communication Tool The program content distribution tool program enables the user to execute the content distribution program 814 described above. Once the content 113 has been approved for distribution , put the SC(s) of the content ιΐ3 into the queue of the inner valley communication program. The content communication tool program supervision O:\85\85156 split DOC-134- 12 55443 This queue, and according to the configuration settings provided by the content provider (8), performs the immediate transmission of the sc(4) case, or the batch transmission of a set of sc(4) buildings. The content provider can also choose to set the content distribution tool. The configuration 'in order to automatically save all SC(s) in the queue, manually marking the SC(4) as releaseable. This way allows the content provider (8) to publish the content at the scheduled time. Prepare the content before the day and save the content until the content provider wants to release an internal user such as a new song, movie, or video game. SC(s) can also control the storage of the content (1) according to a specified issue date. Therefore, the content provider (8) does not actually need to suppress the distribution of sc(4), but such manual distribution options can also be used to manage the network bandwidth required to transfer larger files. When marked as publishable, content 113 The content Sc(s) 630 is transmitted to the designated escrow content website ii via FTP. The mediation material sc(4)(4) is transmitted to the content promotion website 156 via FTP. At this time, sc(s) gradually enters the new content 113.

As part of the 3 literary installation, a public/secret gold (6) pair is generated for the end user device 109 for processing the order and the license SC(s) 660 also generates a random symmetric key (secret user Jin Yu) In order to protect the song encryption key in the license repository 197. Dispersing the secret user key (not shown) into multiple parts, and storing the parts of the key in a plurality of storage locations of the end user computer, Tamper-resistant software technology to protect the code in the area so that it does not leak the way to the key and storage location. P. The access to the Jinyu by the person including the ultimate user helps to prevent the content (1) from being used by other e-months or phoenixes. Right to know more about how to use these keys, see section on SC(s) processor 192.

Tamper-resistant software technology is a computer software application that prevents hackers from gaining unauthorized access. Hackers often want to know and/or modify the software in order to remove restrictions on use. In fact, there is no private smuggling that cannot be cracked. This is why the tamper-proof softness is not called "the reason for guaranteeing that it cannot be falsified. But the amount of work required to crack an application protected against tampering is usually It will frustrate most of the hackers, because the work involved exceeds the possible gains. The work here will be to crack the content i U's gold loss, perhaps on a CD. One of the songs is the gold software. The tamper-resistant software technology from IBM is from IBM. The product that imports the code is the IBM ThinkPad 770 laptop. In this j, the anti-tampering software system is used to protect the DVD in the computer. Movie player. Zhu Yu.\85\85丨56分剤.〇〇〇-162 - 1255443=The digital content provider of the Hollywood movie «etc. cares about the easiness of the digital movie and the copying of the i. The digital content mentioned in the film must be included in the copyright protection machine. IBM's tamper-resistant software makes it difficult to circumvent these copyright protection mechanisms: this is a very typical application of tamper-resistant software; Ding content to enforce certain types of protected use. "Tamper-resistant software BM set up several obstacles in the path of an intruder in the 113's. Brother: 'The tamper-resistant software contains a debugging program that can be used by hackers and a technology that disables or at least reduces the effectiveness of the software program such as Wang. The second tamper-resistant software contains self-completeness. Sex check, so it will detect 4 early modification, even a small amount of modification, and cause incorrect work. Finally, the anti-1 software includes misleading hackers about the ambiguity of their actual work. Finally - most of the technology It is a special technology, but the first two technologies are built according to the well-known tools in cryptography such as encryption and digital signature. The IL 0 c·safe container object processor 192 is collected by the end user in their shopping cart. When the final purchase authorization of the goods is transferred to the electronic digital content store 103, the end user's network browsing protocol remains in the connected state, waiting for a response from the web server. The network on the electronic digital content store 103 The server processes the purchase and performs a financial settlement, and then sends a transaction Sc(s) 640 back to the end user device 109. The web browser launches the Sc(s) processor 192 (assisted application)丄 98) to handle the Sc(s) Multimedia Internet Mail Extension (MIME) type associated with the transaction Sc(s) 640. Figure 14 is a playback application 195 based on 0+\85\85丨56 moments .D〇c -163 - 1255443 This shows an example of a user interface picture that is downloaded to a native repository as shown in Figure i. The sc(s) processor 192 opens the transaction Sc(s) 64() And extract the response HTML page and the quote Sc(s) 641 included in the %(4). It does not respond to the HTML page in the browser window to confirm the purchase of the end user. Then open in the step coffee Quote SC(s) 641, and extract the content 113 (e.g., song or album) name from the newspapers (4) (4), and the estimated download time. Then use the information to display a new window in step 1402, and call the content, for example, for music. And hey, for the song or the entire album) download the schedule options available to the end user. The end user can choose to download immediately, or schedule the download at - later time. If selected - later time Then download the download schedule information in a record, and finally make The device 1G9 starts downloading at the scheduled time when the scheduled time is turned on. 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 message is finally displayed. The user reschedules the download. When the scheduled download_ is reached, or when the download is requested, the %(4) processor 192 utilizes the information in the transaction SC(S) 640, the quote Sc(s) 641, and the installation time. The generated end user public key 661 is generated to generate the order SC(4) 65. The order Sc(s)_ is transmitted to the clearing house 1〇5 via HTTP request. When the clearing house 105 returns the license sc(s) 66〇, the helper application 丨98 is re-processed to process the license sc(s) 66〇. The license SC (4) 660 is then opened, and the web address of the hosted content website 111 is extracted from the referenced order Sc(s) 65〇. Then via the browser's Hrrp request, O:\85\85156 will be split. DOC -164 - 1255443 = can be sc(s) 66 forwarded to the specified hosting content website (1), and ^C(s) 630^ will be requested again. The re-call assistance application VII, eight 198 ° SC (s) processor 192 displays the name of the downloaded guest 113, a bit. Each progress is deducted and an estimated completion time. When Tian Sililu 192 is receiving content 113, the data is downloaded to the record ρ ρ 1 192 , , , Ai Chong District for decryption. The capacity of the buffer: depending on the requirements of the algorithm and the watermarking technology, and the capacity is the minimum capacity I can make for the month, and you, the gentry " reduce v, the unencrypted content 113 leaks to 骇Passenger', I of the code. When the buffer is full, the end user key 623 (corresponding to the public key (6)) extracted from the license SC(4) 6 is used, and the buffer is internally combined with 6 and the secret gold is used first. The key decrypts the key (2) itself. The decrypted buffer content is then transferred to the add-on watermark function. Add sub-watermark private sequence 193 from the license sc (4) (four) extract the watermark refers to T and use the secret key of the end user to take the watermark data from the license SC (4) 6 , the float = material = transaction information such as the name of the buyer, The purchaser name may be the name of the buyer who logs in to the electronic digital content store (8) of the purchase content 113, or may be the name obtained from the credit card login information when the electronic digital content store 103 does not provide a login function. The purchase date and transaction identifier 535 are also included in the watermark, wherein the transaction identifier 5 3 5 is specified by the electronic digital content store 1-3 to compare the particular record recorded for the transaction. It also contains the store usage conditions that will be used for the copy control function of the playback application 5 19 . The tamper-proof code technology is used to protect the watermarking program 1 9 3 so that the O-\85\85156 segmentation DOC-165 - 1255443 will or will omit the watermark instruction, thus preventing the hacker from finding the location and technology of the watermark. This way you can prevent hackers from removing or modifying the watermark. 623, and encrypts the secret user user generated and hidden at the time of installation, that is, the new SEAL key itself. Now the new encryption (4) is stored in the license database from Jinyu Storage. After any necessary watermarks are added to the content buffer, the contents of the buffer are transferred to the out-of-order encryption function for re-encryption procedures 1 94. Content "3 is re-encrypted using a random symmetry key using a processing efficiency such as IBM's SEAL encryption technology. Once the download and decryption and re-encryption process 194 is completed, the content provider is now ruined. The encrypted encryption that originally encrypted the content 113 is different from the source executed at the content provider 101, in the end user device. The user watermarking program executed on 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 music and can be updated several times. An alternative to copy control has been provided in the secure digital content electronic distribution system (7) prior to the copying of fe standards, so that rights management can be provided in consumer electronics without relying on copy control watermarking. The encrypted digital content database 196 that is connected to the end user device 109 implements the security of storage and playback/recording usage conditions, and is secured by the tamper-resistant environment. Only store and play/record the security of the conditions of use. When the standard is adopted, the software tracking point (hook) is used to support the copy control watermark. At present, it is possible to support the addition of watermarking AAC and other encoded audio streams under various compression levels, but at this time the technology is still not mature enough to be used as

O:\85\85 丨 56 minutes DOC -166- 1255443 The only way to copy control. The decryption and re-encryption program 194 is another field of code, in which the code is protected by tamper-resistant code technology so as not to miss the original content m of the encrypted gold, the new SEAL Jin Yu, and the secret user. Jin Yu, and the program in which each secret user is stored and the key segmentation and decryption procedure 194 is used has two purposes. When storing content 113 using a similar-algorithm SEAL encryption, faster instant decryption can be performed and only requires less processor utilization than the more industry standard type of DES such as DES. Perform decryption. This manner allows the playback application 195 to perform content-instant and parallel decryption-decoding-playing on the content 113 without having to decrypt the entire file of the content ι3 prior to decoding and playback. The efficiency of the SEAL calculus* and the efficient casting code (four) method can not only perform parallel operations (streaming of self-encrypting standards... but W can be performed on a system with a much lower performance). The application can be supported on a user device such as a Pentium system with a performance as low as 6 megahertz or a lower performance, and a user device 109. The encrypted content used for the last stored content 11 3 When the encryption format of the original store d, σ Λ, and the original seven is separated, it can be more flexible when selecting the encryption algorithm of the original content. Therefore, a widely accepted and tested industry standard algorithm can be used, thus It further strengthens the digital content industry's acceptance of the secure digital content electronic distribution system 100. The decryption and re-encryption program 94> Chu Yijin 194 has two purposes: no longer need to use the internal provider ιοί The original master encryption gold wheel with the help of the six strokes

The primary encryption key 623, which is only authorized for a short period of time, is stored on the hard disk of the end user device (10), and the primary encryption key 623 is only in the short segment. The time is stored in the memory. During this phase of execution, the key 623 is protected via anti-inversion code technology. Once the decryption and re-encryption 194 phase is completed, it is no longer necessary to retain the Golden Yu (2) in the final user device 109 in any form, thereby greatly reducing the chances of the hacker cracking. Once the song is re-encrypted, the song is stored in the digital content repository 196. In step 1403, all of the mediation data required to play the application 195 is extracted from the associated offer SC(4) 641, and the mediation data is also stored in the digital content repository 196. In the same manner as described above for other content, any addendum in the mediation material such as lyrics is decrypted and re-encrypted.

The text file is categorized as a general playback application = in which the above components are combined into a playback application 195. This is just a few different possible examples - the rest: this is because the playback application 195 is designed to be based on software objects: self-definition specifications. The playback object management program (10) is a software architecture that integrates all of its components: as described in the above sections (4), in the illustration, the components under the playback object 1501 are required in any playback application. The component 'but may be replaced with a special version depending on various factors such as the type of encryption or scribble encryption used, the type of audio compression, and the method of accessing the content H3 library. Above the play object management program 1501 are a number of variable objects 1512, and most of which derive the variable objects 1512 from the mediation material associated with the content 113 being played or searched. The end user device 1〇9 can retrieve these variable objects using the end user display 1510 and the input received from the end user control device 1511.
