At the same time, owners and publishers of valuable digital content have slowed their acceptance of using the Internet to distribute digital assets for several reasons. The first reason is that everyone fears unauthorized copying or ticket plagiarism of digital content. Digital transmission of digital content eliminates several obstacles to plagiarism. ° One obstacle that electronic distribution eliminates is the recording of green media in the physical entity (Example-5-This paper standard _ (CNS) A4 specification ⑽ x Norwegian mm) · Ministry of Economic Affairs Printed by the Consumer Property Cooperative of the Intellectual Property Bureau A7 ______ Β7 V. Description of Invention (3) The Consumer Cooperative of the Intellectual Property Office of the Ministry of Economic Affairs printed 530267 (such as a floppy disk or CD-ROM) itself㈣ 纟. Although copying digital content to media ’is the case in many cases when using blank tapes or recordable green discs = less than a dollar, it always costs money. However, in the case of electronic distribution, physical media is no longer needed. Because it is electronically =, within, the cost of physical media is not a factor *. The second obstacle = is the format of the content itself, that is, the content stored in an analog format relative to the content stored in the: digital format. When copying content stored in an analog format, such as a printed picture temple, by photocopying, the quality of # 贝 is lower than the original quality. Each subsequent copy makes a copy (sometimes referred to as the quality of the first generation and lower than the original quality. When pictures are stored digitally, there is no degradation in quality. Every copy and every generation The copies are as clear and distinctive as the original pictures. Due to the perfect digital copy combined with the integration of electronically distributed content at a very low cost and the extensive distribution of content via the Internet, unauthorized copies are Plagiarism and distribution become easier. Just press a few keys on the keyboard, and illegal copyers can send hundreds or even thousands of perfect digital contents via the Internet. Therefore, 'currently need to ensure the delivery by electronic Protection and security of digital assets. Digital content providers want to establish a security that protects the rights of content owners < digital content all-in-one distribution system. Building a digital content distribution system 2 issues include the development of digital content electronics Delivery, rights management, and asset protection systems. Digital content distributed electronically includes, for example, print media , Movies, video games, programs, television, multimedia, and music, etc. ___________ 6-This paper ^ used the Chinese National Standard (C) ^ S) A4 specification (21〇χ 297 公 -------- Γ Qing first read the phonetic on the back?

Description of the Invention (4) When an electronic distribution system is deployed, digital content providers can quickly receive payment through immediate sales returns and electronic reconciliation, and Receive a second source of revenue through the reissue of the content. Because the electronic digital content distribution system is not affected by physical inventory shortages or returns, digital content providers and retailers can have lower costs and higher profit margins. Digital content providers can assist new distribution channels or strengthen existing distribution channels to distribute inventory faster. The X-Easy data of the electronic distribution system can be used to capture information related to the customer's purchasing model and use it to provide immediate feedback related to electronic marketing plans and promotions. To achieve these goals, digital content providers need to use an electronic distribution model to enable a wide range of users and businesses to access digital content while ensuring the protection and billing of digital assets. Such as real-time audio system (real audi〇), Ατ & τ A2B, Liquid

Audio Pro Corp's Liquid Audio ΡΓ〇, Audio Soft's City

Digital content available on the market, such as Music Network and other systems, electronic content distribution systems provide the transmission of digital data via secured and unsecured electronic networks. When using a secured electronic network, the requirements for digital content providers to distribute digital data to a wide range of viewers are greatly reduced. When using unsecured networks such as the Internet and World Wide Web, encryption can be used to securely deliver digital content to users. However, once the encrypted digital content is decrypted on the user's machine, it makes it easier for unauthorized users to redistribute the digital content. Therefore, there is currently a need for a secure digital content electronic distribution system that provides protection for digital assets and ensures that even when delivering digital content to consumer M-sheet standards, China ’s National Standard (CNS) A4 specifications apply (21〇X 297 mm (please read the precautions on the back before filling out this page) 530267 r A7 _ B7 V. Description of invention (5) The rights of content providers can also be protected afterwards. Therefore, rights management The need for secure distribution, contract authorization, and control of digital asset use. Another reason that digital content owners have slowed their acceptance of electronic distribution is that every digital content owner wants to maintain and promote existing distribution channels. Most Content owners sell through retailers. In the music market, these U.S. retailers include Tower Rectors, peaches, Zeturu, Circuit City, and others. Many of these retailers have websites. Allows Internet users to purchase via the Internet, and can be emailed to users for purchase. Music site Including @ t〇wer, Musk Boulevard, and Columbia House. The use of electronic distribution may make these retail stores indistinguishable from each other, and differentiate from the content owner, especially on the World Wide Web. As such, there is currently a need to provide electronic Inner Valley retailers such as pictures, video games, music, programs, and video products with a way to differentiate between themselves and content owners when they sell music via electronic distribution. The content owner prepares their digital content for electronic distribution via distribution sites such as e-shops. E-shops on the Internet or e-shops via other online services want to go through their product line And product promotions to differentiate between each other. Traditional stores (ie, non-electronic and non-online stores analogous to electronic stores) use product promotions, product salespeople, product samples, free returns policies, and other promotional programs. Books to differentiate them from competitors. However, there is an added use of digital content among content providers. In the online world of electronic parts, electronic stores are differentiated. -8- This paper size is applicable to China ▼ standard (CNS) A4 size (210 X 297 mm) (Please read the precautions on the back before filling this page).

Invention Description (6): The power may be severely restricted. In addition, even if the conditions of use can be changed, the processing The intermediary associated with the digital content from the content provider is data (tadata) in order to use electricity, sub-modes to promote locks and lock-sell products: Difficulties: Works. When an electronic store processes intermediary data, it needs to manage several types: To be the first,% sub-stores need to receive intermediary data associated with digital content: from the content provider. Most of the time may be transmitted in encrypted form, a part of the intermediary data, so the content provider must build a machine i in order to decrypt the encrypted content. Second, the e-shop may wish to receive the content before or from the content provider. Content from content providers in order to facilitate product marketing and other content-related promotion considerations. Third, e-commerce requires the extraction of certain intermediaries: materials such as graphics and entertainers. Electronic stores usually use such promotional materials directly for online promotions. Fourth, electronic stores may wish to modify certain permissible conditions of use, thus creating different digital content product lines that differentiate them from other electronic stores. . Fifth, electronic stores may need to insert certain addresses, such as web addresses, into intermediary materials, or change some addresses in intermediary materials, in order for buyers to automatically pay a billing agency instead of paying to the electronic store . Sixth, e-shops may need to generate a license to allow the use of copyrighted digital content under conditions of use. For example, the license may allow a limited number of copies of the digital content. The license must reflect the terms agreed. In view of all these requirements, in order to process intermediary data related to digital content, many e-shops write software programs of custom specifications in order to process -9- This paper size applies the Chinese National Standard (CNS) A4 specification (21〇x 297 mm) (Please read the notes on the back before filling this page)

530267 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 V. Description of Invention (7) These requirements. The time, cost, and testing required to develop these custom-specified software programs can be considerable. Therefore, there is currently a need for _pair = required solutions. One digital content owner has slowed the acceptance of electronic distribution for another reason—the difficulty of preparing content for electronic distribution. Many content offerings now have thousands or even tens of thousands of product content in their product catalog. In the example of a music market, it is not too strange that the content owner has several different grids for a single recording master (such as CD, green tape, and MD). In addition, an early one format may target a particular distribution channel and remaster or remix a recording master. For example, a mix for broadcast = playback may be different from a mix for dance music tracks that can be different from what a consumer can say. ^^ and = These different mixed versions can be quite cumbersome. In addition, many recording masters often reissue old ^ recordings in a variety of subsequent publishing series, such as "selected collections", or arrange them into movie soundtracks and other published series, or other arrangements. As more content is provided digitally, the need to remix and encode the content for power delivery has grown. Content owners often need to use the old recording format as a guide, choose the correct recording master, reprocess and encode these recordings for distribution via electronic distribution. This is especially true for content providers who want to use their old format to help them redistribute old recordings to power sub-distribution. Content providers will search the database to match content names, artists, and recordings, and set encoding parameters. The procedure for manually searching the recording content directory database is not ----------- order --------- line- ^ wl (Please read the notes on the back before filling this page) -10- 530267 Description of the invention (8) There are no disadvantages. One disadvantage is that you need to make assignments, find a database, and set the parameters appropriately. Behr manual searchers select data in the self-database: one disadvantage is the rate of work. Therefore, there is currently a need for a self-error-associated data and audio master tape. Content owners of content such as Λ prepare their assigned digital content through a program called encoding. Encoding involves content / ,,,,, private subtype, private, digitization of the content when presented in a child & 佴 format, and compression by. This compression program allows the digital content, Λ, μ, ## 六六 +, in a more efficient way to be transmitted via a network and stored on a readable medium, because the amount of transmission or storage is reduced. However, compression is not without its lack of ^, and 枓 又 / and β narrow spots. The big scores all involve the loss of some information, so they are called lossy compression (compression). Content providers must decide on the use of ㈣ compression algorithms and the required level of compression. For example, in music, digital content or songs may have quite different characteristics depending on the type of music. A compression algorithm and compression level chosen for one genre may not be the best choice for another type of music ^. Content providers may find that certain combinations of compression algorithms and compression levels are quite suitable for a certain type of music, such as classical music, but they cannot obtain satisfactory results for another type of music, such as heavy metal music. In addition, green tone engineers often have to equalize music, perform dynamic range adjustments, and perform other pre-processing and processing settings to ensure that the type of music being encoded will produce the desired result. This kind of fixing must manually set these encoding parameters, such as setting the equalization level and dynamic range setting for each digital content. The need may be 11-This paper size is applicable to China National Standard 1 (CNS) A4 specifications (210 X 297 mm) (Please read the notes on the back before filling out this page) Pack 0 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs Consumer Cooperatives 530267

V. Description of the invention (9) It is cumbersome. Going back to the music example, a music content provider whose content series covers multiple music types will have to manually select each song or group of songs to be encoded, and the required combination of encoding parameters. Therefore, what is needed is a method that does not require manual selection of encoding processing parameters. Programs that compress content may require significant dedicated computing resources, especially for larger content projects such as full-length movies. Compression algorithm vendors offer various trade-offs and advantages associated with their compression technology. These trade-offs include the length of time and computing resources required to compress the content; the amount of compression obtained from the original content; the bit transmission rate required for playback; the performance quality of the compressed content; and other factors. When an encoding program takes a multimedia file as an input and generates an encoded output file, but there is no indication of the transition period of the process or status, problems will occur when using this encoding program. In addition, in * Lot of Love>, other programs are used to call or manage a coding program indicated by a transition without a process. This will cause the calling application to measure the amount of encoded content as a percentage of the complete selection specified to be encoded. The problem described above occurs when the calling program is trying to schedule several different programs to run immediately. In addition, when the batch of content to be encoded has been selected and the content provider wants to determine the progress of the encoding process, the situation described above is quite cumbersome. Therefore, a way is needed to solve these problems. Digital content providers have mitigated yet another reason for adopting electronic distribution because their content lacks standards for producing digital players on user devices for electronically transmitted content. Content Provider, Electronic Store, or Electronic -12- This paper has been used in China National Standard (CNS) A4 (210 X 297).

These The advantages of the rights management function are: The infrastructure for electronic digital content distribution does not have to be secure or reliable. Therefore It can be transmitted through network infrastructure such as the World Wide Web and the Internet. This is because the content is added in a secure container object, and the storage and distribution of the inner valley is related to the decryption and use of the content. Quarantine. Only users with a decryption key can decrypt encrypted content, and the clearinghouse will only issue decryption keys for authorized and appropriate use requests. X Exchange will not approve additional requests from unknown or unauthorized persons, Or it does not meet the requirements of the content use 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 decides that 3 € has been tampered with or forged, and refuses to accept the transaction. An end-user playing an application (195) running on an end-user device initiates control of content usage. The application embeds a digital code into the contents of each copy. The digital code specifies the allowable number of copies and playbacks. The digital watermark technology is used to generate the digital code, so that other end-user playback applications (195) cannot know the digital code, and make the digital code resistant to attempts to change. In an alternative embodiment, the digital code is only saved as part of the conditions of use associated with the content (1 丨 3).

Invention Description (21) points. When digital content (113) is accessed in a standard-compliant end-user device, the end-user playback application (195) reads the watermark in order to check usage restrictions and update the watermark when needed. If the required use of the content does not meet the usage conditions, such as running out of copies, the end-user device will not execute the request. Digital watermarks also provide a way to identify the source of authorized or unauthorized copies of content. The content owner embeds an initial watermark into the content in order to identify the content owner, specify copyright information, specify distribution geographic areas, and add other relevant information. A second watermark is embedded in the content on the end-user device in order to identify the content purchaser (or license) and end-user device, specify the purchase or license conditions and dates, and add any other relevant information. Because watermarks become an inseparable part of the content, whether the copy is authorized or unauthorized, the content must contain these watermarks. Therefore, no matter where the content is stored, and no matter what the source & source of the digital content, digital content must contain information about the source and permitted use of the content. This information can be used to combat illegal use of the content. 2. Measure the records of all transactions approved by the clearing house through the clearing house, approved by the exchange, as part of its rights management function. This record measures authorized access to the original conditions of use. This transaction record may be reported to various responsible parties, such as content owners or content providers, retailers, and other relevant partners, in an immediate or regular manner to facilitate the reconciliation of transaction payments electronically, and Other uses.

Description of the Invention (29) The content electronic distribution system 100 supports a point-to-point distribution mode such as the Internet and a broadcast distribution mode such as digital broadcast television. Although the same tools and applications are used to obtain, encapsulate, and track content n3 transactions via various transmission infrastructure 107, the performance of providing services to customers can be changed according to the selected infrastructure and distribution model Ways and methods. The quality of the transmitted content i 13 may also be different because the high-frequency bandwidth transmission infrastructure can transmit high-quality digital content with a more acceptable response time than the low-frequency bandwidth transmission infrastructure.

530267 A7 --------- B7_____ 5. Description of the invention (32) To ensure the security of a confidential message using the public Jinyu algorithm 'must be used to encrypt the message using the recipient's public key. Only recipients with the relevant 2 secret keys can decrypt the message. It also uses the public key algorithm to calculate the parameter signature. Secret keys are used for this purpose. The next section provides information related to digital signatures. The commonly used public key algorithm is RSA public key cryptography. RSA public key cryptography has become the industry's de facto standard for public key. Other algorithms that are also quite good for encryption and digital signatures include mGamal and Rabin. RSA is a variable key length cipher. Symmetric key algorithms are much faster than public key algorithms. The speed of DES in software is roughly at least twice that of anti-§8. Therefore, RS A is not used to encrypt large amounts of data. rS a data security report On a machine using a 90 megahertz Pentium CPU, the rs A data security tool suite BSAFE 3.0 has been used in secret key operations (forking or solution using secret keys). The following generation rate: 21.6 kilobits per second with a modulus of 5 12 bits, and 7.4 kilobits per second with a modulus of 1024 bits. C. Digital signature In the secure digital content electronic distribution system 100, the sender of the SC (s) digitally signs the SC (s) to protect the integrity of the sc (s). Generally, in order to generate a digital signature of a message, the owner of the message first calculates the message digest (which will be described below), and then encrypts the message digest with the owner's secret key. Deliver the message with its signature. Any recipient of the message can first decrypt the signature using the public key of the owner of the message in order to recover the message digest and verify the digital signature. 35- This paper size applies to China & Family Standard (CNS) A4 (210 X 297 mm) (Please read the notes on the back before filling out this page) ---- Order --------- Line < Ministry of Economic Affairs Intellectual Property Bureau Employee Consumption Cooperative Printed Ministry of Economic Affairs Wisdom Printed by the Consumer Cooperatives of the Property Bureau 530267 A7 -------_ V. Description of Invention (33). The child recipient then calculates a digest of the received message and compares the digest with the recovered digest. If the message has not been changed during the distribution process, the calculated digest must be the same as the recovered digest. In the secure digital content electronic distribution system 100, since Sc (s) contains several data points, a summary is calculated for each part, and a summary summary is calculated for the summaries of the sequential parts. The summary digest is encrypted using the secret key of the scrambler. The encrypted summary digest is the SC (s) digital signature of the sender. The summary of each part and the digital signature are included in the ontology of SC (s). The receiver of Sc (s) uses the received digital signature and partial digest to verify the integrity of the SC (s) and its components. A one-way hash algorithm is used to calculate a message digest. A messy algorithm takes a variable-length input message and converts the input message into a fixed-length string, that is, a message digest. The one-way clutter algorithm operates in only one direction. That is, it is easy to calculate a digest of an input message, but it is very difficult (computationally infeasible) to generate an input message from its digest. Because of the nature of the one-way mess function, we can treat a message digest as the fingerprint of the message. The most common one-way messy functions are MD5 from RSA 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 who has transmitted a digitally signed message. A certificate is issued by a certification authority that combines a public key with a person or entity. -36-This paper size is applicable to the Chinese Standard (CNS) A4 (210 x 297 mm) I U ---------- " ^ 装 -------- Order --------- line (Please read the precautions on the back before filling this page) 530267 A7 __ _ B7 Fifth, the digital file of the invention description (34). The certificate includes the public key, the name of the person or entity, the expiration date, the name of the authentication center, and other information. The certificate also contains the digital signature of the certification authority. When an entity (or person) sends a message signed with its public Jinyu accompanied by its digital certificate, the recipient of the message uses the entity name from the certificate to decide whether to accept the message. In the secure digital content electronic distribution system 100, each SC (s) other than the one issued by the end-user device 109 contains a certificate of the producer of the sc (s). Because many end users do not need to obtain a certificate or hold a certificate issued by a non-authentication certification center, the end user device 109 does not need to include the certificate in its sc (s). In the secure digital content electronic distribution system 100, the clearinghouse 105 can choose to issue a certificate to the electronic digital content store 103. This allows the end-user device 10 to independently verify that the secure digital content electronic distribution system 100 has authorized the electronic digital content store 103. E.SC (s) Guidelines for Graphical Representation This document uses a graphic representation to represent SC (s).

V. Description of the invention (46) Compression algorithm. The content 113 is stored in compressed form on the end-user device 109 in order to reduce the storage capacity requirement. Content 113 is decompressed during actual playback. It is easy to perform decoding during actual playback. The purpose and type of encoding will be explained when the content use control layer 505 is discussed later. 2. Content use control layer 505 The content use control layer 505 allows the conditions or restrictions imposed on the use of the content 113 on the end user device 109 to be regulated and enforced. These conditions may specify the number of times the content 113 is allowed to be played, whether subsequent copies of the content 3 are allowed, the number of subsequent copies, and whether the content 3 can be copied to an external portable device. The content provider 101 sets an allowable use condition ^ 517, and transmits the use condition 517 to the electronic digital content store 103 in the form of a sc (see this section discussing the authorization controllable layer 501). The electronic digital content store 10 may increase or decrease the use condition ^ as long as the use condition 517 does not invalidate the original condition set by the content provider 101.

Content 113 itself is not included in these sc's. This is because the capacity of Content 113 is usually too large for the digital content store 103 and end users, and it is not possible to efficiently download containers just to access descriptive intermediary data. object. sc (s) instead contains an external Uniform Resource Locator (URL) pointing to the content 113. sc⑻ also contains: intermediary information that provides descriptive information related to content 113, and any other associated information that is a CD cover picture in the case of music, and / or a digital audio clip in the case of song content 113 . The electronic digital content store 103 downloads its authorized intermediary material Sc (s) 620 and creates a quote SC (s) 641. In short, the offer SC (s) 641 contains additional information from the intermediary; some components of the SC (s) 620 and the bom, and the electronic digital content store 103. When the quotation SC (S) 641 is created, a new bom of the quotation SC (s) 641 is generated. The electronic digital content store 103 also uses the intermediary data SC (s) 620 to extract the intermediary data information from these intermediary data 'and build an interactive HTML page on its website to provide the description of the content 113 to the end user, so the end user May purchase content 丨 丨 3.

When an end user decides to purchase the content 113 from an electronic digital content store 103, the offer SC⑷641 is included in a transaction sC⑷64. The electronic digital content store 103 establishes a transaction SC (s) 64 0 and includes a quote SC (s) 641 for each item 113 purchased, and transmits the transaction% ⑷ 640 to the end-user device 10 9. The end-user device 109 receives the transaction SC (s) 640 and confirms the integrity of the transaction SC ⑷ 640 and the included quote% ⑷ 6 41. The end-user device 109 creates an order SC (s) 650 for the purchased content 113 item. The configuration file for the self-quote SC (s) 641, transaction Sc (s) 64, and the end-user device 109 contains information. The orders SC (s) 650 are transmitted to the clearing house 105 one at a time. The website of the clearing house 105 which received the order% ⑷65 is included as one record in the bOM of the intermediary material Sc (s) 620, and the website of the clearing house 105 is included in the quote Sc (s) 641. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints the X exchange 105 to verify and process the order sc (s) 650 in order to provide the end user with all the information required to authorize the watermark 527 and access the purchased content 113 Device 109. One function of the clearing house 105 is to decrypt the watermark instruction from the quote SC (s) 641 and decrypt the inner valley 113 from the content Sc (s) 63〇, and decrypt the required symmetric key 623. One encrypted symmetric key 623 record actually contains more than one actual encrypted symmetric key 623.

Description of the invention ( 129) The problems can be identified earlier to process the content more efficiently. Therefore, it is very desirable to guarantee the quality of the content in this step, rather than waiting until all processing is completed at the end. 4 · Encryption Tool Program The encryption tool program enables the user to execute the encryption program 811 described above. Content encryption is the last step of the content processing tool ι55. Each version of the content previously generated using the encoding tool program is now encrypted. The encryption utility is a function of the SC (s) encapsulation utility. The SC (s) encapsulation tool is called to encrypt the song and return the generated encryption key. This key is then placed in the SC (s) encapsulation tool program for use in generating the intermediary data SC (s) 620. E. Content SC (s) generation tool program Once all the intermediary data is collected, the content Sc (s) generation tool program divides the intermediary data into several types according to the intended use of the intermediary data. The mediation data of these groups are written into the file and put into the s C encapsulation tool program as the mediation data part of the mediation data SC (s) 620. Each component (building case) has unique processing requirements. Once the associated song is processed and encrypted, and the destination (the URL of the hosting content website u 丨) is determined, the content SC (s) 630 of the content 113 is ready to be generated. The processing has been completed and meets all the requirements described above. The content 113 is waiting in the queue to be encapsulated in the queue of the encapsulation tool program of the workflow management program 54. The content SC (s) generation tool now retrieves all the necessary files generated by the previous steps of the assimilation of the intermediary data and enters the tool program 161, and calls each SC (s) encapsulation tool program function to generate the intermediary data sc ( s)

Description of the invention (162) Depends on the requirements of the encryption algorithm and watermarking technology 193, and the capacity Is the smallest possible capacity to reduce the amount of unencrypted content 113 leaking guest code. When a buffer area is full, the end user key 623 (corresponding to the public gold inspection 661) extracted from the authorized license SC (s) 660 is used to decrypt the content of the buffer area, and the secret gold is used first. Yu decrypts the 2 key 623 itself. The decrypted buffer content is then transmitted to the watermark function. The watermarking program 193 extracts the watermark instructions from the authorized license Sc (s) 660, and decrypts the instructions using the secret key of the end user. However, the watermark data is extracted from the authorized license SC (s) 660. The watermark data includes transaction information such as the name of the purchaser, and the purchaser name can be = registered in the electronic digital content store 103 of the purchase content 113. The purchaser's name or the name obtained from the credit card login information when the electronic digital content store 103 does not provide a login function.

It also contains store usage conditions 195 to be used for the copy control function of the playback application 519. Utilize anti-corruption coding technology to protect the watermarking program 19 3 so that the watermark instruction will not be leaked, so as to prevent hackers from discovering the location and technology of the watermark. This method prevents hackers from removing or modifying the watermark. After adding any necessary watermarks to the content buffer, the contents of the buffer are sent to the out-of-order encryption function for re-encryption. Use a processing efficiency package such as IBM's SEAL encryption technology -------- Order -------- (Please read the precautions on the back before filling this page) 165- 530267 Ministry of Economic Affairs Intellectual Property Bureau employee consumer cooperative prints A7 ______B7 _-V. Method of invention description (彳 64). The program that unpacks and re-encrypts program 194 serves two purposes. When storing SEAL-encrypted content, which looks like a different method, it can perform faster instant decryption, and requires less processor utilization than more industry-standard types of calculations such as DES. Decryption is performed. In this way, the playback application program 195 can perform a real-time and parallel decryption-decoding-playback 'on the content 113 without decrypting the entire file of the content n 3 before decoding and playback. The efficiency of the SEAL algorithm and a high-efficiency decoding algorithm can not only perform parallel operations (streaming playback of self-encrypting files), but also execute the program on a much lower-performance system processor. Therefore, the application can be supported on an end-user device 10 such as a Pentium system with a performance as low as 60 MHz or a system with a lower performance. When the encryption format used for the last stored content 113 is separated from the original encryption format, there is greater flexibility in selecting an encryption algorithm for the original content. Therefore, the widely accepted and tried-and-tested industry standard algorithms can be used, thereby further strengthening the acceptance of the digital content industry's secure digital content electronic distribution system 100 by the digital content industry. The second purpose of the decryption and re-encryption program 194 is to eliminate the need to store the original master encryption key 623 used by the content provider 101 to encrypt the content 113 in each end user who obtained the content. 13 Device 109. The master encryption key 623, which is part of the license sc (s) 66, is buffered and stored on the hard disk of the end-user device 109 only for a short period of time, and the master encryption key 623 is Stored in memory for a short period of time.
