We use random superimposed codes as sequences for collusion-resistant flngerprints. This approach is more suitable in comparison with the use of some other regular sequences (as WBE-sequences) against watermark removal attacks and traitor tracing is done through the sphere decoding algorithm. The performance evaluation of the proposed method is presented and the simulation results show an acceptable e‐ciency.
