[0086] The second embodiment is a digital rights management method for multi-device content sharing:

[0087] The second embodiment provided by the present invention adopts an algorithm based on a check code, and the specific process is as follows image 3 Shown:

[0088] Step 201: Register the PC, portable reader and notebook to the registration server. Since user A's portable reader is not easy to connect to the Internet, a PC (or notebook) needs to be used as a registration agent for the portable reader, so first register user A's PC and portable reader to the registration server, that is, send a registration request. When registering, send the SIDi (i=1) according to the device identification of the PC (such as generated by the motherboard number, CPU number and hard disk number of the PC) to the registration server, and simultaneously send the device identification SIDi (i=2) of the portable reader ), sent to the registration server.

[0089] During the specific implem...

Abstract

The invention discloses a digital right management method, a system and a server thereof for multiple equipment with shared content; aiming at solving the problem of providing the secrete key of digital content which can be shared for multiple equipment without depending on the environment of an area, by utilizing the secrete key of each user equipment, the invention carries out traversal encryption to the secrete key of digital content, binds authentication information corresponding to each user equipment with cryptograph obtained by encrypting the secrete key of digital content and providesthe secrete key of the shared digital content of multiple registered equipment.

Description

technical field [0001] The invention belongs to the field of DRM (digital rights management, digital rights management), and in particular relates to a digital rights management method, server and system for multi-device content sharing. Background technique [0002] DRM technology is to realize the protection of digital content such as e-books, digital movies, digital music, pictures, software, etc. through a series of software and hardware technologies. It uses digital licenses to protect the copyright of digital content. After users get the copyrighted content, they must obtain the corresponding digital license and use the digital content according to the usage rights granted in the digital license. The most common practice nowadays is to authorize each user individually and bind the digital license to the current terminal device, that is, to grant the right to use the digital work to a specific device of the user, so that the copyright work can only be used in a specifie...
