Abstract

In this work we propose the use of random superimposed codes as sequences for collusion-resistant fingerprints. This approach seems to be more suitable in comparison with the use of some other regular sequences (as WBE-sequences) against watermark removal attacks. Sphere decoding algorithm is used for tracing traitors. The performance evaluation of the proposed method is presented. Simulation results show a good efficiency of the proposed codes.
