Multi Reduce Permuted Share Visual Cryptography Technique

Visual Cryptography is an exceptional encryption technique to conceal information in images in such a way that it can be decrypted by the human visualization if the correct key image is utilized. Visual cryptography (VC) is a way of protecting the secret image which encodes the image into various shares and distributes them to various members. In k out of n (k, n) method, the secret image is allocated into n shares such that when k or more members by assembling their limpidity through an overhead projector to divulges the secret image. This work proposes a novel, simple and hard to decode (k, n) visual cryptography procedure which is used to successfully sharing the secret image with extreme concealment. We have used permutation for n share, so that it becomes impossible for an outsider or attacker to decrypt the message encoded in an image.
