Recursive visual cryptography for multiple secret image sharing

Abstract

The concept of traditional visual cryptography encrypts one image by converting it into random pixel image.This paper uses recursive visual cryptography to encrypt more than one color images.This method is also solving the problem of Pixel expansion as for recursive Visual Cryptography the original image is not necessarily double the size of secret image.This method solves the problem of reconstructing image as it uses XOR based Visual Cryptography.
