Size Invariant Extended Visual Cryptography Scheme
Conventional (k, n)-threshold visual cryptography scheme encodes one secret image into n random-looking shares, of which size is larger than that of the secret image. When any k or more shares are superimposed together, the secret image is visually revealed. In this paper, a novel (k, n)-threshold size invariant extended visual crvptography scheme is presented. The size of shares generated by the proposed scheme are the same as the secret image. Besides that, the innocent-looking of the shares make them easy to recognize and manage. Simulation results demonstrate these advantages as well.
