Method and system for interacting equipment with permission server

Abstract

The present invention discloses an equipment in the digital copyright management system and a permission server LS interactive method, the method includes: firstly, an entrusting equipment and an entrusted equipment set up an entrustment relation. The entrusted equipment obtains an agent entrusting equipment and a LS interactive authorization. Secondly, the entrusted equipment interacts with the LS according to obtainedauthorization, the LS sends the information relative to the authorization obtained by the entrusted equipment to the entrusting equipment. In the present invention, the entrusting equipment is directly deputized through the entrusted equipment which has connection with the LS, so as to realize an equipment with connection deputizing the other equipment directly, and enable the other equipment to obtain the needed information; otherwise, in the present invention, the entrusting equipment and the entrusted equipment can make information interaction through the method of document transmission, thereby the entrusting equipment, the entrusted equipment and the LS need not to be on line at the same time, but the entrusting equipment can still realize to obtain the needed information form the LS place.

Description

technical field [0001] The invention relates to the technical field of digital rights management, in particular to a method for interacting between a device and a license server in a digital rights management (DRM) system and a system for interacting between a device and a license server in the DRM. Background technique [0002] DRM technology is a new technology developed with the widespread dissemination of digital media content on the Internet.

Problems solved by technology

[0006]In the above prior art, the connected device can only forward signaling between the non-connected device and the LS, and it is impossible for the connected device to directly proxy the non-connected device and the LS Interaction; and since the connected device simply forwards the signaling, it is required that the non-connected device, the connected device and the LS must be online at the same time to realize the signaling forwarding
