Abstract :
Inspired by a previously proposed constructive framework for the distributed source coding problem. We propose a powerful constructive approach to the watermarking problem, emphasizing the dual rules of distributed source coding with side information at the decoder and channel coding with side information at the encoder. In our framework, we explore various source and channel codes to close the gap on the achievable capacity of watermarking systems. We propose two methods of solution, one which is based on optimal rate-distortion quantizers and the other based on robust optimization and convex programming. The resulting watermarking schemes, when subjected to additive white gaussian noise (AWGN) attacks, achieve results which are comparable to or better than the best watermarking schemes in the literature
