| 摘 要： | 基于混沌对初值的敏感性和混沌伪随机序列的唯一性，以DCT变换为工具，给出了混沌数字水印生成及嵌入的算法，兼顾了水印的鲁棒性和透明性。实验结果表明，该方法提高了水印图像的不可见性和鲁棒性，具有极强的抗攻击性。

| Abstract: | In this paper, an image watermarking algorithm in DCT domain based on chaotic map is presented. The algorithm is robust and secure due to the sensitivity of the original state and the uniqueness of the chaotic map. The experimental results show that the algorithm is good at invisibility and robust on implementating the watermarking. |
