摘要/Abstract

摘要： 基于异或运算,结合计算机显示技术的特点,提出了一种完全恢复的(2,n)彩色视觉密码方案。该方案以构造行向量${{V}_{1}},{{V}_{2}},\cdots ,{{V}_{n}}$为基础,设计了彩色秘密图像的分享算法,通过共享份异或并对得到的图像进行处理,完成秘密图像的恢复。实验结果表明,在保留视觉密码秘密恢复简单特点的基础上,方案以较低的像素扩展度为代价,能够实现秘密图像的完全恢复,每个参与者只需携带一个共享份,降低了共享份的管理难度。

Abstract: Based on XOR operation and combining the characteristic of computer display technology, a perfect recovery (2,n) color visual cryptography scheme was proposed. Sharing algorithm of color secret image was designed on the basis of constructing row vectors${{V}_{1}},{{V}_{2}},\cdots ,{{V}_{n}}$. Through computing shares by XOR operation and dealing with recovery image, the secret image was recovered. The experimental results show that the scheme on the basis of keeping the simplicity in the reconstruction phase of visual cryptography can realize the secret image perfect recovery with low pixel expansion for price. Each participant only needs to carry a share which reduces the difficulty of share management.
