本文提出了一种新的基于码分多址技术的图像保密系统（称为多址隐像术），它把数幅秘密图像的信息加密后隐藏在另一幅可公开的图像中，而不同接收者可恢复出相应的秘密图像。试验结果表明：恢复密图的ＰＳＮＲ值可达２１ｄＢ，证明了图像多址隐像术有满意的恢复质量 This paper presents a new image encryption system based on code division multiple access (called multiple-access image concealment), which encrypts several pieces of secret image information and then hides it in another openable image, The recipient can recover the corresponding secret image. The experimental results show that the PSNR of the recovered image can be up to 21dB, which proves that the image multiple-access image has a satisfactory quality of recovery
