Visual Cryptography: A Literature Survey

Abstract

Visual cryptography(VC) is a cryptographic methodology which permits visual information, for instance, text, pictures, etcetera to be encrypted such that the decryption can be performed by the human visual framework, without the assistance of PCs. The aim of this survey paper is to provide the readers a layout of the first visual cryptography method, along with the various methods developed and proposed from time to time. This paper also gives a survey of the applications that are based upon the concept of Visual Cryptography.
