END-TO-END DIGITAL RIGHTS MANAGEMENT ON THE OVERALL VALUE-CHAINS OF CONTENT DISTRIBUTION

摘要

Current studies on Digital Rights Management (DRM) have focused on security and encryption as a means of solving the issue of illegal copying by purchasers. In this paper, we propose End-to-End Digital Rights Management (E2E DRM) that can cover a content protection on the overall value-chains of content distribution. We establish an E2E DRM model and architecture, and propose key management that makes it possible to protect content from content creator to purchaser.
