A DRM system suitable for P2P content delivery and the study on its implementation

P2P (peer-to-peer) architectures like Gnutella, which support direct file sharing among peers, are attracting interest these days. At present, however, P2P file sharing is infamous for copyright infringement, making the establishment of rights management technologies an urgent need. In this paper we discuss a digital rights management (DRM) system applicable to P2P content sharing, and focus on DRM methods and assignments of DRM functions, and we propose functional assignments suitable for P2P content delivery, and also describe a trial implementation.
