Abstract

We propose a powerful new solution to the multimedia watermarking problem by exploiting its duality with another problem for which we have recently made pioneering constructive contributions. This latter problem is that of distributed source coding, or compression of correlated sources that are distributed. We show how these two seemingly unrelated problems are actually duals of each other. We exploit this duality by transforming our recently introduced powerful constructive framework for the distributed compression problem in [13] to a corresponding dual framework for the watermarking problem. Simulations expose the significant performance gains attained by our proposed watermarking approach and reveal its exciting potential for next-generation watermarking techniques. This can be accredited to the exploitation of the dual roles played by source codes and channel codes in the two problems.
