| 摘 要： | 提出了一种新的基于SVD（奇异值分解）的图像数字水印算法.该算法具有以下几个特点：采用二值图像作为水印;换对二值图像进行Arnold置乱预处理;没有直接将二值图像嵌入到载体图像,而是通过二值图像的不同取值,将伪随机序列嵌入到各子块的奇异值中,增加了安全性;具有良好的不可见性;对常见的信号处理具有良好的抵抗攻击能力;采用相关检测提取水印,不需要原始载体图像参与.

| Abstract: | A new algorithm of image watermarking based on SVD is presented. Watermark image is firstly permuted with Arnold transformation. According to two different values of watermark image, two random sequences is embeded into singular values of every block. Experimental results demonstrate that the watermark is invisible and robust against common signal processing. When extracting watermark, it does not need the original cover image but two secret keys. |

| Keywords: | singular value decomposition binary image Arnold transform pseudorandom sequence blind watermark |
