摘　　要：为了达到版权保护的目的,提出一种Contourlet变换与生命游戏置乱相结合的视频零水印,Contourlet被誉为处理二维信号的最优解,算法利用其优势对关键帧处理得到低频系数,再经过核心算法处理,最后结合生命游戏规则生成特征图像,并运用加密算法对水印进行预处理以加强安全性。实验结果表明本算法较好地折中了数字水印的不可见性和鲁棒性,并能有效地抵抗常见的几何攻击和视频攻击。In order to achieve the purpose of copyright protection , this paper proposes a video zero-watermark algorithm based on the combination of the life game scrambling with Contourlet transform , which has been known as the optimal solution of two-dimensional signal processing .The algorithm uses the advantage of Contourlet to process the key frame and gets the low -frequency coefficients, then combines the rules of the life game to generate feature image with core algorithm , and uses encryption algorithm to make pretreatment for watermark in order to enhance security .Experimental results show that the algorithm is a good compromise between invisibility and robustness , and can effectively resist the common geometric attacks and video attacks .
