Abstract
Abstract. Buyer-seller watermarking protocols integrate watermarking techniques with cryptography, for copyright protection, piracy tracing, and privacy protec-tion. In this paper, our main contribution is the development of an efficient buyer-seller watermarking protocol based on homomorphic public-key cryptosystem, and the use of composite signal representation in the encrypted domain to re-duce both the computational overhead and the large communication bandwidth which are due to the use of homomorphic public-key encryption schemes. Both complexity analysis and simulation results confirm the efficiency of the proposed solution, suggesting that this technique can be successfully used in practical ap-plications.
