Method and system for limiting using part of using medium content

Abstract

A method, a system, a Rights Issuer and a user terminal are provided for restricting the users of media content. For restricting the users of media content, a DRM agent inside a user terminal obtains the copyright control information that carries the user identity of the current media content, receives a rights verification request that carries the identity of the current initiator of the current media content, and checks whether the current initiator can trigger the play of the current media content according to the user identity in the copyright control information mentioned previously and the identity of the current initiator carried in the rights verification request. If the current initiator is allowed to trigger the play of the current media content, the DRM agent provides the current decrypted media content to a media player. Otherwise, the DRM agent forbids the media player to play the current media content. The users of media content can be restricted based on the actual service requirements and thus a media content provider can better control the right to use its media content.

Description

technical field [0001] The present invention relates to digital rights management (DRM) technology, in particular to a method and system for restricting trigger users of media content. Background technique [0002] DRM technology is a new technology developed with the widespread spread of streaming media on the Internet. The purpose of DRM technology is to protect the copyright of digital content, technically increase the technical threshold and cost of piracy, and ensure that only users who purchase copyright can enjoy digital content under the condition of abiding by copyright rules. [0003] The basic realization principle of DRM technology is: the publisher of the media content encrypts the media content in the form of a digital signal and uploads it to the network; the user terminal downloads the encrypted media content from the network to the copyright agent (DRM Agent) inside the user terminal; The DRM Agent inside the user terminal obtains the copyright control info...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above description that in the prior art, the rights information obtained by the user terminal from the rights issuer does not include the specific trigger user information that the user terminal can use the media content, that is, It does not limit what kind of application program in the user terminal or whether the user itself can be used as the trigger user to trigger the playback of the media content, which greatly reduces the media content provider's control over the media content usage rights and damages the media content.
