A new visual cryptography using natural images

Abstract

In this paper an (n, n) visual cryptography scheme without dithering is proposed. This scheme takes n grayscale input images to cover a target image across n grayscale images and produces n grayscale output images which are very close to the input images, respectively. Since the output images are visibly innocuous and natural, it may be easy to pass visual… (More)
