摘要 为了减小参与者的负担,本文基于布尔运算提出了一种像素缩小的(2n,2n)秘密共享方案,该方案通过Arnold变换和加密算法将一幅图像共享成2n幅大小为原图像1/2n的分存图像,只有所有分存图像共同存在时才能够无质量损失地恢复出原图像信息。对比研究表明了该方案的有效性和优点。 A pixel contractible secret sharing scheme (2n,2n)based on Boolean operation and Arnold trons-form is proposed to decrease the burdens of participants.This scheme divides an image into 2n pieces (shares)in such a way that each piece has the size of 1/2n of the original image and only all shares are a-vailable can we restore the original image without any quality loss.Comparative study shows the effective-ness and performance of the proposed algorithm.
