In this paper a visual cryptography scheme with a binary additive stream cipher is used to form the meaningless shares (share images or multiple layers) of original digital image, hiding some secret information. Each share image holds some information, but at the receiver side only when all of them are superimposed, the secret information is revealed by human vision without any complex computation. Proposed algorithm for generating shares is applied in MATLAB programming environment, using MATLAB built-in functions to create sequences of pseudorandom numbers or streams, which are used to make share images of original digital image. The input image …
