【摘要】 为了能够完全无失真的提取隐藏图像,在双随机相位加密的基础上,提出了一种对彩色图像进行加密隐藏的方法。通过构造宿主图像矩阵,可以将待隐藏的彩色图像编码信息的实部和虚部同时隐藏于该宿主图像矩阵中,避免了已有方法需要传输多幅图像的不足。模拟实验结果表明,该方法不仅安全系数高,保密效果好,而且能完全无失真的提取隐藏图像。更多还原

【Abstract】 In order to extract the hidden image without distortion,a new technique of color image encryption and decryption method based on double random phase encoding technique is proposed.By constructing the host image matrix,the real and imaginary parts of the encoding data can be hidden in the corresponding part of the constructed host image matrix simultaneously which avoid the deficiency of multiple images transmission.The experimental results show that the method is effective in high security,well confidentiality and the recovered image is the same as the original hidden image.更多还原
