Imperceptible watermark for a game-theoretic watermarking system

This paper advances the game-theoretic approaches to design a robust watermarking scheme for embedding watermark in an image in discrete wavelet transform (DWT) domain. A reliable architecture for imperceptible watermarking system that provides an optimal solution for decision makers is proposed. Using iterative Elimination of strictly dominant strategies (IESDS), an optimal solution is computed to attain the best trade-off between embedding and extraction of the watermark. Under different attacks and strategies, embedder could be able to obtain the best strategy. Experimental results attested the fact that the proposed approach is robust to various signal and image processing attacks.
