摘要

本文针对二值图像、灰度图像和彩色图像,提出了一种精确重构的(2,n)秘密图像共享方案。在共享阶段,采用基于xor的秘密共享方案,要求每个参与者持有一定数量的共享,每个共享与秘密图像大小相同。在揭示阶段,每两个参与者只需进行简单的布尔运算,就可以精确地恢复原始秘密图像。该方法计算复杂度低,能够精确地重建秘密图像。实验结果表明,该方案简单有效。

(2, n) Secret Image Sharing Scheme with Ideal Contrast
In this paper, we propose a (2, n) secret image sharing scheme with precise reconstruction for binary, grayscale and color image. In sharing phase, XOR-based secret sharing scheme is utilized and each participant is required to hold a certain number of shares, each having the same size as the secret image. In revealing phase, each two participants can recover the original secret image precisely by just performing simple Boolean operation. The proposed scheme has low computational complexity and can reconstruct the secret image precisely. Experimental results show our scheme is simple and effective.
