The piracy tracking is a important task in copyright protection system for the digital work. The traditional copyright protection system could not prevent the badness customer copying and reselling the digital work and could not prevent the badness author replacing the customer's fingerprint. In this paper, a novel secure scheme is proposed for the piracy tracking. In this scheme, a secure copyright protection authority and the fingerprints of the author and the customer are used. After described the architecture of the copyright protection authority, the secure author fingerprint protocol and the secure customer fingerprint protocol are discussed. Based on the copyright protection authority and the fingerprint protocols, the pirate root identification protocols for the abstract and the finished product of the digital work are proposed. After tested in the IPTV system and analyzed in the aspect of security, the proposed scheme and protocols are high performance and secure.
