%X Visual Cryptography is a technique in which a secret is encrypted into several image shares and then decrypted later using a human visual system to stack all the share images. Conventional visual cryptography methods divide a secret image into n shares (shadows) and distribute these shares to n participants. But in network while transmission the shadows can be changed by attackers or damaged. To remedy such kind of vulnerabilities verifiability of shadows can be a solution. Watermarking can add verifiability to secret sharing. But the shadows are meaningless which can attract the attacker's attention. The proposed scheme embeds created shadows in cover images which make them more secure. In this paper we have explained how a low computational complexity visual secret sharing scheme is verifiable and more secure by combining Watermarking and Steganography.
