REGION BASED VISUAL CRYPTOGRAPHY SCHEME FOR COLOR IMAGES.
Abstract : A region based visual cryptography scheme deals with sharing of image based upon splitting the image into various regions. The main concept of visual secret sharing scheme is to encrypt a secret image into n meaningless share images. It cannot leak any information about the original image unless all the shares are obtained. The original image is obtained by superimposing all the shares directly, so that the human visual system can recognize the shared secret image without using any complex computational devices. In this paper we propose a region based visual secret sharing scheme for colour images with no pixel expansion and high security.
