Visual Cryptography (VC) is a secret sharing scheme in which an image is converted into shares.VC uses two transparent images, one image contains random pixels and other image contains the secret information. VC is a cryptographic technique which allows visual information (picture, text, etc.) to be encrypted. This paper, the different methods of visual cryptography. No information can be revealed by observing any share. Different significant research advances are identified in this paper to ease reader to sort out similarities and differences in various methods of VC.
