摘要：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 Moni Naor and Adi Shamir[1]. Visual cryptography scheme (VCS) is a method to encode a secret image into n shadow images called shares. The recovered secret image can be darker or lighter than the background. The secret data or secret information is hiding in the image using several encode and decode technologies. In this paper, the various methods are populated and reviewed their applications.
