Color Visual Cryptography Scheme for Secret Sharing

Abstract :

Visual Cryptography Scheme (VCS) is a scheme for sharing a secret among a set of participants. By using VCS, the image can be encoded into parts or pieces each part or piece is called a share, and each share is given to a participant. In this paper, we proposed a visual cryptography scheme for embedding color secret image into two meaningful covers, and focused on improving the quality of the reconstructed secret by choosing meaningful covers that are close in similarity to the secret image. Experimental results proved that the process of choosing meaningful covers, close in similarity to the secret image, can help in improving almost
