Problems solved by technology

[0006] In the above-mentioned prior art, the domain members are managed uniformly by the DMC on the network side, and because the number of domain members managed by the DMC on the network side is relatively large, the burden on the DMC on the network side is severe; and since the DMC is located on the network side, The terminal must interact with the DMC through the Internet. For devices that do not have remote connections, such as portable players, they cannot join the domain

Embodiment Construction

[0102] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0103] The main idea of ​​the present invention is to set a local domain manager (LDM) on the local side to manage the local terminals, thereby reducing the burden of the DMC on the network side.

[0104] The DRM domain management system of the present invention includes LS, domain information storage module, LDM and terminal. Wherein, the LS and the domain information storage module are located on the network side, and the LDM and the terminal are located on the local side. The domain information storage module can be located in the LS, or it can be the existing DMC. The following domain information storage module is DMC, such as figure 2 As shown, the system of the present invention is described in detail as a specific embodiment.

[0105] LDM is used to sav...

Abstract

The invention discloses a DRM regional management system and building method of local region and allowing method of terminal obtaining local region, which comprises the following parts: local side region manager and terminal, website side regional information storage mode and allowing server, wherein the local regional manager reserves local regional information to add or leave local region according to terminal request or makes terminal add or leave local region directly, which sends regional information to terminal in the local region; the terminal transmits local regional allowing request with local mark to allowing server, which proceeds allowing consumption according to regional allowance of allowing server; the regional information storage mode can reserve local regional information; the allowing server generates regional allowing and sends regional allowance to terminal according to regional information corresponding to local regional allowance in the regional information storage mode.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a digital rights management (DRM) domain management system, a method for establishing a local domain and a method for obtaining a local domain license. Background technique [0002] DRM mainly controls the use of digital content through rights restriction and content protection schemes, and protects the legitimate rights and interests of content owners. After the publisher of the digital content encrypts the digital content, the user downloads the encrypted digital content data package to the terminal device; the license server is responsible for distributing the license corresponding to the digital content, including the content decryption key and the corresponding authority. The purchased digital content can only be used normally if the device has both the content data package and the license that contain the information necessary to decrypt the digital content. ...
