| 摘 要： | 基于矩阵乘法秘密共享思想,提出了一种新的可压缩的图像秘密共享方案。本方案利用可压缩矩阵乘法算法直接生成影子图像,有效地克服了秘密图像需进行置乱预处理的缺陷,并且方案的复杂度较低。本方案生成的影子图像仅为原秘密图像的1/t,有效地压缩了影子图像的尺寸。

| Abstract: | Based on matrix multiplication secret sharing theory,a new compressible image sharing scheme is proposed.Taking advantage of compressible matrix projection,this scheme directly creates shadow image so as to,consequently,effectively overcome the drawback which requires the secret image is permutated before it is shared in literature.Besides,its complex degree is lower than the scheme's one in literature.Meanwhile,this scheme reduces the size of each shadow image to become 1/t of the secret image's one. |
