Embodiment Construction

[0027] like Figure 1-3 As shown, the digital copyright protection system of this media network application includes:

[0028] An authentication server, connected to the Internet, handles user registration requests and authentication requests, and issues key certificates to users who pass authentication requests. It includes a user database and a rights management database. The user database is used to record and manage registered user information, rights The management database is used to store the authorization information of each media file uploaded by the media file owner;

[0029] A data server, connected to the Internet, that stores media files uploaded by media owners; and,

[0030] A number of clients, which are connected to the Internet for encryption, authorization, decryption and playback of media files, each client includes,

[0031] Encryption module for media owners to encrypt their media files,

[0032] Authorization module for media owners to authorize speci...

Abstract

The media document owner encrypts his media documents via a encrypt module on the user end, and then uploads the encrypted documents to the data server via network. The owner manages the use right ofthese encrypted document by himself. This system includes the authentication server connected to the Internet, the data server and several user ends. Every user end has encryption module, authorization module, decoder module and playback module. The media document owner encrypts and authorizes their documents at the user end. It decreases the load of system server, increases the encryption efficiency. It is easy to renew the algorithm and is flexible and easy to use. The user will feel more confident by possessing the power of authorization.

Description

technical field [0001] The invention relates to information sharing and protection technology in network applications, in particular to a digital copyright protection method and system for media network applications. Background technique [0002] With the popularity of the Internet, a large number of multimedia applications are spread through the Internet. How to ensure that the copyright owner of the media data is not infringed by piracy, and how to ensure that the content of the network media data is not tampered with and destroyed has become the focus of multimedia applications in the network industry. question. The existing copyright protection methods for network applications are mainly centralized management, and the server is responsible for encryption and rights distribution, which increases the burden on the server, and the management of the server is also very complicated. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a dig...
