A Novel Embedding Method For An Anti-Collusion Fingerprinting By Embedding Both A Code And An Orthogonal Fingerprint

In this paper, a fingerprint embedding method better-suited for the AND anti-collusion code (AND-ACC) is proposed. The proposed method embeds both a code and an orthogonal fingerprint using different basis vectors depending on the bit. Although the detection for the embedding method is complex, the performance of the fingerprinting system using proposed embedding method with the AND-ACC against average attack is improved compared with the AND-ACC fingerprinting scheme using code modulation embedding method. The system using the proposed embedding method is robust against the linear combination collusion attack (LCCA) whereas the system using the code modulation is not
