Buyer-seller watermarking protocols integrate watermarking techniques with cryptography, for copyright protection, piracy tracing, and privacy protection. In this paper, we propose an efficient buyer-seller watermarking protocol based on homomorphic public-key cryptosystem and composite signal representation in the encrypted domain. A recently proposed composite signal representation allows us to reduce both the computational overhead and the large communication bandwidth which are due to the… CONTINUE READING
