中文摘要：

将加权的二元相息图隐藏于彩色的宿主图像中，采用彩色图像直方图相似度研究了加入隐藏信息以后宿主图像色彩的变化以及隐藏信息权值对宿主图像色彩畸变的影响。被隐藏的二元相息图由原始待加密图像采用基于相息图迭代的双随机相位加密技术，用有记忆的模拟退火算法获得。该方法既保证了隐藏信息的安全性，又提高了信息提取时的光学效率，解码过程不依赖于原宿主图像。讨论了水印图像的不同剪切度对隐藏信息提取质量的影响。模拟实验结果证明了该方法的有效性。

英文摘要：

A weighted binary kinoform is added to a color host image and the color clistorfrom of the watermarking image is discussed based on histogram similarity of color images. The binary kinoform to be hidden is obtained from an original image using double-random phase encryption and memory based simulated annealing technique. Through the method, the security of hiding information can be ensured, and the optical efficiency of information extracted, can be improved. The decoded processing of the method is independent of the original image. The efficiency and the robust of this method is analyzed. Computer simulations are presented to illustrate the effidency of this method.
