On the duality between distributed source coding and data hiding

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 roles of "source codes" and "channel codes". In our framework, we explore various source and channel codes to achieve watermarks that are robust to attackers in terms of maximizing the distortion between the corrupted coded-source signal and the original signal while holding the distortion between the coded-source signal and the original signal constant. Simulations show that performance gains are accredited to a careful choice of source and channel codes.
