Embodiment Construction

[0036] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0037] The primary measure of the present invention to realize the safe distribution of video discs is to add information to the video discs, besides encrypting media data, disc IDs, registration software, and safe players are also set. During specific implementation, the disc ID can be printed on the cover of the disc, and the rest of the information is stored in the disc data, see the attached figure 1 . Of course, the disc ID can also be stored in the disc data in text or other formats.

[0038] The user holds such a video disc, and the service provider provides a registration authentication server with a user database. The user submits a registration request to the registration authentication server through the user computer, and the registration authentication server sends a registration authentication to the user computer after passing the regis...

Abstract

The invention relates to a method for securely distributing video compact disks. The method is characterized in that: a video compact disk is set with four kinds of information including a video compact disk ID, registration software, secure player software and encrypted media data; a service provider provides a registered certification server configured with user data base, and the information stored in the user data base comprises all valid video compact disk IDs and corresponding keys; a user computer loading the video compact disks establishes a communication link with the registered certification server, and the secure certification is realized by the communication link; and after the secure certification is realized, the secure player software is used for realizing the valid play. Byusing the distributing scheme provided by the invention, only user computers which are securely registered can play the video compact disks. The encrypted media data in the video compact disks can beplayed by secure players; and even if the unauthorized users copy the encrypted media data, the encrypted media data cannot be played. Therefore, the method has the advantages of high security, easyimplementation, low cost and important market application value.

Description

technical field [0001] The invention belongs to the technical field of digital copyright protection, in particular to a method for safely distributing video discs. Background technique [0002] Video discs are the main carrier of multimedia audio-visual products, and also the main target of a large number of illegal duplications by piracy. At present, the authority control of the user is generally carried out in advance through the optical disk encryption technology. Only legal users who are authorized to obtain the media key can decrypt the disc data and play the video normally. However, once the plaintext is decrypted, the disc data has no protection measures at all, allowing pirated copying, and a large number of intellectual property rights have been violated. Therefore, realizing safe distribution of video discs is an urgent problem to be solved in the technical field of digital copyright protection. Contents of the invention [0003] The purpose of the present inv...
