| 摘 要： | 针对目前水印安全性不够,以及水印鲁棒性和不可见性的矛盾,提出了一种新的水印设计思路：水印在双重置乱的基础上,进行汉明编码,然后嵌入在二维小波变换图像的高频上.实验结果表明,该水印算法除了具有较好的保护水印安全外,而且水印不可见性好,鲁棒性高.

| Abstract: | The article proposed a new watermark design concept in view of the current lack of watermark safety along with the conflict between robustness and invisibility of the watermark.The watermark carries on Hamming codes in the dual scrambling＇s foundations and then embedded in image of two-dimensional wavelet transform on high frequency.The experimental results indicated that the watermark algorithm can protect the safety of the watermark.Moreover,the watermark invisibility is sound and robustness is high as well. |
