Digital Watermarking, Proceedings
We analyze the security of a fingerprinting scheme proposed at IWDW 2005. We show two results, namely that this scheme (1) does riot provide seller security: a dishonest buyer can repudiate the fact that, he redistributed a content, and (2) does riot, provide buyer security: a buyer can be framed by a malicious seller.
