Information Security has become an inseparable issue in the rapid growth of computer and communication technology. Data is vulnerable to various attacks. Although, cryptography schemes are used to protect data, still it suffers various issues viz., computational complexity, processing delay and more storage medium. Visual Cryptography (VC) is an emerging cryptographic scheme, which splits an image into different shares in its encryption process and the image can be decoded by stacking the shares with each other. Decryption process is not required any cryptography knowledge as it requires the human visual system to retrieve the original image.
