Abstract

The embodiments of the present invention relate to the field of communication technology, and in particular to a digital rights management method, device and system, which are used to solve the problem in the prior art that new devices cannot be added to share protected digital content during the process of using protected digital content. Problems with digital content. A digital rights management method according to an embodiment of the present invention includes: the first user equipment that has shared the digital content generates a public public key according to the public keys of all the second user equipment that have shared the digital content; according to the public public key pair Encrypting the key of the digital content to generate a ciphertext of the key of the digital content; generating a new authorization certificate corresponding to the digital content according to the ciphertext; and sending the new authorization certificate and the digital content to the second user equipment, Instructing the second user equipment to share the digital content according to the new authorization certificate. The embodiment of the present invention realizes adding new user equipment to share the digital content in the process of using the digital content.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a digital copyright management method, equipment and system. Background technique [0002] DRM (Digital Right Management, Digital Rights Management) technology realizes the protection of digital content such as e-books, digital movies, digital music, pictures, and software through a series of software and hardware technologies. DRM protects the copyright of digital content through the use of digital authorization certificates, that is, after users obtain copyrighted content, they must obtain the corresponding digital authorization certificate and use the digital content in accordance with the use rights granted in the digital authorization certificate. At present, the most commonly used method is to individually authorize each user and bind the protected digital content with the user's current device, so that the acquired digital content can only be used on the bound de...
