摘要:

利用概率法构造了一种防欺骗视觉密码方案,在不需要其他额外信息的前提下,可发现欺骗者的存在。同时,本方案还可以控制秘密图像的恢复效果。仿真实验表明,该方案扩展度小,恢复效果好,并可以通过控制概率来调整秘密图像的恢复效果。

Abstract:

An anti-cheating Visual Cryptography Scheme (VCS) scheme based on probability, which can find the cheaters without extra information, was proposed. Meanwhile, the visual effects of recovered secret image could be controlled in this scheme. Performance analysis and simulation results show that this scheme has little pixel expansion and the visual effect of recovered secret image can be adjusted by controlling probability.
