Abstract |
This paper proposed a novel reversible visual secret sharing method. Without any computing, if we stack two transparencies directly, a secret image will appear. Stacking two transparencies after reversing one of transparencies, another secret image will unveil. Different from traditional reversible visual cryptography, the method not only has advantages but also will not have pixel expansion and code-book. Besides, the same idea can be extended to complex style visual cryptography. |
