Abstract

Visual Cryptography is one of the techniques that can be used for securing image based secrets. The scheme Visual Cryptography is used to encrypt a secret image or document by breaking into shares. In order to take the advantage of this property, the third party can recover the secret image if the shares of secret image are passing in sequence over a network. This paper presents an approach to encrypt generated image shares of Visual Cryptography using chaotic random number. This is paper encrypt the image based on the sieving, division, chaotic random based shuffle shares. Destination gets the original image from cipher image by decrypting the cipher image in same reverse approach. My research goal is to provide high security for image data.

Keywords

Sieving, division, chaotic random based shuffle shares, encryption, decryption, halftone.
