Applications and usage of visual cryptography: A review

Abstract

Visual cryptography is a cryptographic technique which allows visual information to be encrypted in such a way that decryption becomes a mechanical operation that does not require a computer. In this paper, we intend to study the different application areas of Visual Cryptography. Visual Cryptography is a wide area of research used in data hiding, securing images, color imaging, multimedia and other such fields. Visual Cryptography comes in the field of data hiding used in cybercrime, file formats etc. This paper focuses on the application areas of visual cryptography from four different research papers/journals which talk about the most important application areas of visual cryptography.
