A survey on digital tracing traitors schemes

Abstract

The encroachment of Internet and Peer to Peer networks has really facilitated our daily lives and works but it contributes to another dangerous phenomenon which is copying a digital content without having authorization, called piracy. To handle this phenomenon, several techniques of tracing traitors were proposed, by combining in the same time a fingerprinting technique to a watermarking one. In this paper, we first present basic notions for multimedia traceability framework: Anti Collusion code (ACC) and the watermarking technique. We show a study of available tracing traitors' schemes and we propose a comparison of accusation ability and computational costs of these techniques. Next we describe our future contribution in this target.
