FLMP: a flexible license management protocol for digital rights management

摘要

Most existing license management schemes for DRM systems do not support the protection of user privacy; moreover, some other schemes such as PrecePt can only bind the license to a specified device though privacy protection is concerned. In this paper, we propose a flexible license management protocol named FLMP (Flexible License Management Protocol) which provides a more powerful and flexible license management scheme to satisfy the various requirements of users for privacy protection and use convenience.
