Problems solved by technology

[0003] The existing DRM system does not have a unified standard, and it is characterized by diversity and heterogeneity, so it cannot achieve interoperability
Different content providers (Content Providers, hereinafter referred to as: CP) provide digital copyright protection through different DRM systems. User terminals must support multiple DRM systems at the same time, and obtain media content licenses from multiple DRM systems before using media content. Thereby bringing inconvenience to the user and seriously affecting the user experience
Since the user terminal must support multiple DRM systems at the same time, the computing power of the user terminal is relatively high, especially the user terminal with limited computing power such as mobile phones, set-top boxes and PDAs cannot support multiple DRM systems

Embodiment Construction

[0048] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0049] Such as figure 1 As shown, it is a working principle diagram of the integrated DRM system in the first embodiment of the integrated DRM system of the present invention. The integrated DRM system exists as an independent device, and multiple CPs are using other and different DRM systems (hereinafter referred to as "background DRM systems"). ") DRM1, DRM2...DRMt encrypts the media content and sends it to the media content server. The integrated DRM system decrypts and re-encrypts the content. User 1, user 1...user n only need to register in the integrated DRM system, and the integrated DRM system In this way, rich media content provided by multiple CPs can be re-encrypted and then distributed to user terminals, and the integrated DRM system can shield different DRM systems used by different CPs.

Abstract

The invention relates to a method for realizing a digital copyright management system and a digital copyright management system. The method for realizing a digital right management system comprises the following steps: receiving a media content encrypted by a back-end digital copyright management system; decrypting the encrypted media content according to a special license transmitted by the back-end digital copyright management system; re-encrypting the decrypted media content; transmitting the re-encrypted media content to a media content server; receiving a license request message transmitted by a service platform to generate a license; and transmitting the license to a user terminal corresponding to the media content. The invention realizes interactive operation between the DRM systems of diversity and heterogeneity, is convenient for users to operate, reduces the requirement on the computation capacity of the user terminal and simplifies the complexity of the user terminal.

Description

technical field [0001] The invention relates to communication technology, in particular to a method for realizing a digital rights management system and the digital rights management system. Background technique [0002] Digital Rights Management (Digital Right Management, hereinafter referred to as: DRM) technology is a technology to strengthen the copyright protection of audio, video and other media content. In the prior art, user terminals order media content according to requirements, and the service platform sends the user order information to the DRM system, which generates a license (License) and sends it to the user terminal. A user terminal supporting DRM acquires DRM-protected media content from a media content server, and the user must hold a license to use the media content. [0003] The existing DRM system has no unified standard, and has the characteristics of diversity and heterogeneity, so it cannot realize interoperability. Different content providers (Con...
