Visual Cryptography (VC) is a special kind of encryption techniques which is applied to hide the data in images. The image can be decrypted by using correct key image. Visual cryptography method is introduced by the researchers. Visual Cryptography Scheme (VCS) is a method to encode a secret image into n shadow images called shares.
