Abstract

A DRM Agent based on trust computing theory and a method thereof relate to digital copyright management technical field, for resolving the protection problem of digital copyrights. The DRM Agent comprises a trust computing module, an authentication and login module, a copyright information management module, a content processing module, and a daemon process and share data module which are connected with each other, wherein the copyright information management module requests, receives and manages RO; the content processing module decrypts encrypted digital information product and controls use; the trust computing module verifies the integration of DRM Agent code at client and the accuracy of client time; the daemon process and share data module initializes DRM Agent, processes real-time monitor, shares data among all modules, interacts data and coordinates all modules. The invention can effectively confirm the integrality of DRM Agent code, having high application safety.

Description

technical field [0001] The invention relates to the technical field of digital rights management (DRM), in particular to the technology of a digital rights management agent system (DRM Agent) residing in a client device in a DRM system. Background technique [0002] With the advent of the information age, interactive Internet TV IPTV, electronic publishing houses, online education and other industries that provide services for the use of digital information products have made great progress, and these industries have greater and greater value. In such a period, it is more necessary to effectively protect the copyright of digital information products than in any previous period. Digital Rights Management (DRM) was born under such a background. [0003] DRM technology mainly realizes the protection of digital copyright through digital information product content encryption, authorization management and other technologies. Its three basic elements are encrypted digital informa...
