基于生命游戏的数字图像置乱与数字水印技术

Digital Image Scrambling and Digital Watermarking Technology Based on Conway's Game

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 .

In this paper, aiming at the problems of digital image security and encryption and digital watermarking which are becoming popular recently, the authors from another point of view present a kind of digital image scrambling encryption and digital watermarking technology. Firstly, the authors introduce a kind of special image matrix transform ——John Conway's Game; then generalize it to the algorithm for digital image scrambling encryption in the position space; furthermore, based on the rules of Conway's Game, the authors present a novel digital watermarking technology. The experimental results show that the algorithm satisfies the robustness requirement of digital image encryption and hiding to a certain extent .
