针对近年兴起的数字图像安全保密和数字水印等问题 ,从另一个角度提出了一种数字置乱加密技术和数字水印植入技术 .首先 ,探讨一类特殊的图像矩阵变换—— John Conway提出的生命游戏 ;然后将生命游戏扩展为数字图像的位置置乱加密算法 ;此外 ,根据生命游戏的规则 ,提出了一种新颖的数字水印植入技术 .从试验结果来看该算法可以在一定程度上满足数字图像加密和隐藏的鲁棒性要求 In view of the problems of security and digital watermarking and digital watermarking in recent years, this paper proposes a digital scrambling encryption technology and digital watermarking technology from another perspective.Firstly, a special kind of image matrix transformation is discussed, which is proposed by John Conway Life game, and then extend the life game to the position scrambling and encryption algorithm of digital image.In addition, according to the rules of life game, a novel digital watermarking technology is put forward.From the experimental results, the algorithm can to a certain extent Meet the robustness of digital image encryption and hiding requirements
