Visual Cryptography for Security of Images

Abstract

Visual cryptography is a cryptographic system which enables visual data to be scrambled such that unscrambling turns into a mechanical operation that does not require a PC. In this paper, we expect to contemplate the diverse application zones of Visual Cryptography. Visual Cryptography is a wide territory of research utilized as a part of information covering up, securing pictures, shading imaging, sight and sound and other such fields. Visual Cryptography comes in the field of information stowing away utilized as a part of cybercrime, record groups and so on. This article presents Comparative study of various visual cryptographic Techniques which are used for security of images.
