Secret Hiding Using Visual Cryptography

Visual Cryptography is the technique in which secret images or visual text are encrypted or hided in a manner such that only human visual system can decrypt the hided images or text without any help of cryptographic computations or algorithms. The human visual system can decode the secret image when all the shared cover images are stacked together. In this paper, we recover the color secret image from multiple cover images using Chang-s and Yu visual cryptography scheme. This scheme gives lossless recovery and reduced noise. Also cryptographic computation complexity is very less.
