Visual Cryptography is a secret-sharing scheme that uses human visual system to perform complex computations. In this paper, first the background with the Visual Cryptography Scheme (VCS) has been established and the fundamental concepts have been explained. Then, a VCS algorithm has been presented to encode a grayscale image which uses a different approach from the traditional ones.
