Abstract

The invention discloses a digital media management method based on an identification. The method comprises the following steps that: when a client accesses a media supply server, an identification server obtains the certificates of the client and the media supply server according to the identifications of the client and the media supply server, and verifies the identities of the client and the media supply server; after the client and the media supply server pass the identity verification, the client and the media supply server negotiate to obtain a message identification key and a business key; and the client and the media supply server perform secrecy transmission of the digital media resources according to the message identification key and the business key. The invention also provides a digital media system. According to the embodiment of the invention, the media supply server and the client are subjected to unified authentication, and secrecy transmission of the digital media resources between the media supply server and the client is realized.

Description

technical field [0001] The present invention relates to the technical field of digital information network, in particular to an identification-based digital media management method and system. Background technique [0002] Digital media technology has the advantages of high transmission quality, wide range, multiple clients, and fast speed. It can be transmitted on the Internet, cable TV network, and even wireless networks. It is foreseeable that digital media will gradually replace traditional media and have a very broad market prospects. [0003] As a new media application mode, digital media needs to solve the following problems in terms of distribution, transmission, management and protection compared with traditional media: [0004] (1) How to implement conditional access, that is, only legal clients can receive digital media content, and non-legal users cannot receive it. The legitimate client here refers to a client that has been certified by the digital media-relat...
