Real-time-control-oriented client-side system for protecting digital copyright of electronic book and implementation method thereof

Abstract

The invention discloses a real-time-control-oriented client-side system for protecting the digital copyright of an electronic book and an implementation method thereof. The client-side system comprises a reference monitor, an electronic book reader and trusted system hardware, wherein the reference monitor is used for providing permit protection, decision making and updating; the electronic book reader is used for operating digital contents; the trusted system hardware is used for providing security protection for the reference monitor and the electronic book reader; and the reference monitor is used for carrying out decryption and decision making on a permit, and granting the right of the electronic reader so that the electronic book reader carries out corresponding operations. In the client-side system disclosed by the invention, a UCON ABC model is adopted as a decision-making model, while a nontraditional access control model can carry out positive auditing on the right use condition instantaneously, and an effective real-time control function can be achieved. In addition, UCON REL is designed based on XML (Extensive Makeup Language), so that the system has good openness and expandability and enriches the use of control function for a client side.

Description

technical field [0001] The invention relates to an e-book reading system, which belongs to the technical field of mobile reading, in particular to a real-time control-oriented e-book digital copyright protection client system and method. Background technique [0002] Wireless reading is a new mobile Internet value-added service. Operators set up a large number of e-book resources on the server side to provide users with a mobile phone reading platform, and mobile phone users can read online, offline or download e-books through the mobile Internet. In the actual application process, in order to protect the copyright of e-books and safeguard the legitimate interests of copyright owners, it is necessary to manage the use rights of e-books. [0003] At present, DRM (Digital Right Management) digital rights management technology is generally used to manage authorization and usage rights. The existing DRM system adopts the license pre-authorization mode, and all authorizations ar...

Problems solved by technology

[0004] Aiming at the lack of comprehensiveness, lack of real-time control ability, and lack of scalability of the existing DRM system, the present invention proposes a real-time control-oriented e-book digital copyright protection client system, which improves the traditional authorization model into UCON ABC uses the control model to transfer part of the authorization to the mobile reading client. This more flexible authorization method solves the problem of real-time authorization control, and makes the protection of digital copyright have good scalability and security.
