Embodiment Construction

[0035] Aiming at the problem that digital rights management in the prior art cannot authorize works from multiple sources, the embodiment of the present invention composes the contents of multiple digital files selected by the user into a new digital file, and sends the new digital file to the client. The authorization information of the file, thus realizing the authorization of works from multiple sources.

[0036] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 As shown, the first digital rights management method in the embodiment of the present invention includes the following steps:

[0038] Step 101, the server side composes the contents of multiple digital files selected by the user into a new digital file;

[0039] Step 102, the server side encrypts the new digital file, and generates an authorization message according to the key used for encryption and the info...

Abstract

An embodiment of the invention relates to the field of DRM, particularly to a method, a system and a server for the DRM, and is used for solving the problem that the DRM cannot authorize a plurality of source works in the prior art. The method includes that the server forms a plurality of digital files selected by a user into a new digital file, encrypts the new digital file, generates authorization information according to a key used during encryption and client information logged by the user, and sends the authorization information to the client to inform the client to apply the new digital file according to the authorization information. According to the method, the system and the server, the content of the plurality of digital files selected by the user are formed into the new digital file, the authorization information for the new digital file is sent to the client, and therefore authorization to the plurality of source works is achieved.

Description

technical field [0001] The invention relates to the field of digital copyright protection, in particular to a digital copyright management method, system and server. Background technique [0002] With the development of network technology and digital publishing technology and the popularization of various terminal servers, users' demand for more abundant digital content works is increasingly obvious. [0003] Generally, the application of digital content works is to authorize digital content works from the same source, which lacks support for users to use digital content works personalizedly. This authorization model for digital content works from the same source cannot carry out more detailed authority management and use control on digital content works, and cannot meet the application requirements of users for multi-source digital content works. In order to meet the personalized needs of users, fine-grained copyright protection is required for multi-source digital content...
