摘要

本文提出了一种全新的可视密码，即可逆式可视密码。对于任意两个给定的秘密图像，可以产生两个对应的透明片S1和S2，也称为份额。两张透明照片看起来都很嘈杂。然而，如果我们叠加两个透明的正面视图，那么第一个秘密图像就揭晓了。另一方面，如果我们将S1的前视图与S2的后视图(翻转)叠加在一起，那么第二个秘密图像就会揭晓。

Visual Cryptography in reversible style

We proposed in this paper a brand new type of visual cryptography (VC), namely, the VC in reversible style. For any two given secret images, two corresponding transparencies S1 and S2, also known as shares, can be produced. Both transparencies look noisy. However, if we stack the front views of both transparencies, then the first secret image is unveiled. On the other hand, if we stack the front view of S1 with the back view (the turn-over) of S2, then the second secret image is unveiled.
