Abstract
Visual cryptography is a secret sharing method that uses human eyes to decrypt the secret. It has computation-free decoding process to decrypt the images. Generally visual cryptographic methods utilize the technique of secret sharing in which secret image is divided into shares and when k shares out of n stack together the secret image will reveal. In this paper we proposed a method of visual cryptography for colored images. We are using RGB color model for color images. First of all, image is divided into monochromatic channels then converts each individual image to binary image. After this we can apply basic VCS scheme. The secret image can be recovered by stacking share images. We are using Matlab7. 4 for implementing our scheme.
