Visual cryptography is a special image encryption technique. It is different from traditional cryptography, because it does not need complex computation to decrypt. The benefit of the visual secret sharing scheme is in its decryption process where without any complex cryptographic computation encrypted data is decrypted using Human Visual System (HVS). But the encryption technique proposed here uses a new k-n secret sharing scheme for color image where encryption (Division) of the image is done using Random Number generator and to decrypt the image at least a group of k shares out of n shares reveals the secret information, less of it will reveal no information.
