A License Management Model to Support B2C and C2C Music Sharing

Digital Rights Management (DRM) technology ensures protection of rights on distributed music over the Internet. Existing DRM systems emphasize the protection on Businessto-Consumer (B2C) distribution model, but pay very little attention on the protection of Consumer-to-Consumer (C2C) distribution model – referring to peer-to-peer sharing. In this paper, we propose a license management model to support not only the music distributor to consumer (B2C) music distribution, but also consumer-to-consumer music sharing. The proposed license management model consists of two types of license; namely official license and peer license. We proposed to implement these licenses using XrML.
