A Survey Paper on Visual Cryptography Technique
Abstract
With the approaching era of natural philosophy commerce, there is associate imperative ought to solve the matter of guaranteeing info safety in today’s more and more open network atmosphere. The encrypting technologies of ancient cryptography area unit sometimes accustomed shield info security. Visual cryptography is associate rising cryptography technology. It is a special cryptologic technique wherever decoding is completed by a licensed user by merely overlaying the shares. It uses the characteristics of human vision to decipher encrypted pictures. It wants neither cryptography information nor advanced computation. For security issues, it conjointly ensures that hackers cannot observe any clues a few secret images from individual cowl pictures. So, there is a requirement to style away by that a binary image may me encrypted and decrypted simply in a very secure manner. This paper provides a review of the visual cryptography.
