A New Watermarking Scheme Based on Two Chaotic Maps

In this paper, we propose a new watermarking method base on chaotic maps of Arnold and Logistic. The map of Arnold is used to permute the image and Logistic map is used as the second key to XOR the sequence produced from the Arnold map. Furthermore, the traditional binary embedding watermark sequence is generalized in our scheme, which makes the watermark embedding more flexible and convenient. Experiment shows that the proposed watermarking approach is feasible and robust to common signal processing procedures. In addition, it exhibits more security than other watermarking methods using only one chaotic map.
