摘要：Information’s are being transferred through open channels and the security of those information hasbeen prime concerns. Apart from many conventional cryptographic schemes, visual cryptographic techniques have alsobeen in use for data and information security. Visual cryptography is a secret sharing scheme as it breaks an originalimage into image shares such that, when the shares are stacked on one another, a hidden secret image is revealed. TheVisual Cryptography Scheme is a secure method that encrypts a secret document or image by breaking it into imageshares. A unique property of Visual Cryptography Scheme is that one can visually decode the secret image bysuperimposing shares without computation. Even to make the visual cryptography image shares more secure, publickey encryption scheme is applied. Public key encryption technique makes image shares so secure that it becomes veryhard for a third party to decode the secret image information without having required data that is a private key.
