Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail by giving specific embodiments and referring to the accompanying drawings.

[0063] There is a delay in the integrity verification of the protected content in the prior art because the hash value of the protected content needs to be calculated and then compared with the hash value in the rights object, because calculating the hash value of the protected content is a very long process. Time-consuming process, so there is a delay in the integrity verification of the protected content in the prior art. The method proposed by the present invention is: store the calculated hash value of the protected content to be compared with the hash value in the authority object, and directly obtain the stored hash value when verifying the integrity of the protected content later. The hash value of the protected content is compared ...

Abstract

The invention discloses a kind of method, device and system to verify the integrity of the protected content. The method includes: storing the hash value of the protected content of the computer, during verifying the integrity of the protected content before consuming the protected content, users' device compares the hash value of the protected content with hash value of the authority target related to the content, if they are accord, the content passes the verification of the integrity; or does not passes. The invention solves the problem that the users can not experience very well because consuming the content verifying the integrity of the content frequently leads to the delay of consuming the content. Further, the situation of no-consumption authority target consumes the consumed content with the system.

Description

technical field [0001] The invention relates to a technology for processing protected content in a digital rights management (DRM) system, in particular to a method, device and system for verifying the integrity of the protected content. Background technique [0002] DRM technology is a new technology developed with the widespread dissemination of digital content on the Internet. The purpose of DRM technology is to protect the copyright of content, technically increase the technical threshold and cost of piracy, and ensure that only users who purchase copyright can consume protected content under the condition of abiding by copyright rules. DRM technology can effectively prevent users from illegally copying, backing up and sharing protected content through the Internet or storage media, thereby ensuring the interests of media content publishers and digital media licensing distributors, and is a prerequisite for selling protected content through the Internet . [0003] The ...
