Abstract |
This paper proposed a new visual secret sharing method. The property of visual secret sharing in reversible style is that it can be applied without depending on any computing If one stacks two transparencies together straightforwardly, a secret image will appear. Stacking two transparencies after reversing one of the transparencies, another secret image will unveil. Different from the traditional visual secret sharing with reversible property as previously proposed by Fang in 2007 and 2009, the method not only can fast decode while causing no pixel expansion but also increase the secret-hiding ratio. Based on the probabilistic method ,the experimental results showed that applying the technique proposed in this paper, it was possible to make the size of secret equal to that of the share. |
