Secure and Verifiable (2, 2) Secret Sharing Scheme for Binary Images


Sonali Patil, Sandip Sathe, Pravin Mehetre, Deepak Shinde, Kiran Bhalerao and Pawankumar Pandey

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.
