Cryptography is study of transforming information in order to make it secure from unintended recipients. Visual Cryptography Scheme (VCS) is a cryptography method that encrypts any information picture, printed text, etc. such that decryption can be performed using human visual system. This paper is to give the readers an overview of the basic visual cryptography schemes constructions, as well as the new techniques derived from VCS. The authors also review some applications that take advantage of such secure schemes.
