具有掩盖图像且像素不扩展的渐进式可视密码

渐进式可视密码不同于传统的可视密码,它的概念是通过叠加两张以上的分享图像,即可逐步地还原秘密信息。以渐进式可视密码为基础,提出一个具有掩盖图像且像素不扩展的渐进式可视密码方案,并且将分享图像的样式扩充为多张伪装图像,解决了以往渐进式可视密码中像素扩展和分享图像杂乱无章的问题。...

Summary:渐进式可视密码不同于传统的可视密码,它的概念是通过叠加两张以上的分享图像,即可逐步地还原秘密信息。以渐进式可视密码为基础,提出一个具有掩盖图像且像素不扩展的渐进式可视密码方案,并且将分享图像的样式扩充为多张伪装图像,解决了以往渐进式可视密码中像素扩展和分享图像杂乱无章的问题。

Progressive visual cryptography（ PVC） is different from the traditional visual cryptography,which recovers the secret gradually through adding more than 2 shared images. Based on this,this paper proposed a modified PVC scheme to produce the non-expansion and meaningful shares,and extended the number of the camouflage images from single-meaningful image to multiple-meaningful images. The proposed scheme can solve two problems,such as the pixel-expansion and the shared images disorganized.
