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 .

A real-value encryption and decryption method is proposed for the optical image security system.A full-phase image to be encrypted together with a random phase mask is Fourier transformed and real part of the result is used as an encrypted image.The addition of encrypted image and the Fourier transformed of the random phase is inverse-Fourier transformed.The intensity values of the inverse-Fourier transformed image is adjusted.It gives the exact original image.The method of encryption and decryption is simply performed and encrypted image is real-valued,so it is convenient for print or display on computer.

一种用于纯相位图象加密的实值编码方法 ,待编码的纯相位图象与一个随机相位掩膜一起作傅立叶变换 ,取其实部作为编码图象。已编码的图象和随机相位掩膜的傅立叶变换相加作傅立叶反变换 ,记录反变换的光强分布 ,再通过图象灰度变换可以恢复图象。该编译码方法简单 ,编码图象是一个实值图象 ,便于计算机打印或显示输出
