Sai Ho Kwok, Siu Man Lui · 2001
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.
