Visual Cryptography is a special type of encryption technique which is used to hide the information and data in images. In this technique the decryption process is done without any complex cryptographic computation. The encrypted data is decrypted using Human Visual System (HVS). This is the benefit of the visual secret sharing scheme. The encryption technique requires a cryptographic computation to divide the image into a number of parts or the authors can call it shares. They divide the image into n number of shares. In this paper, they have proposed a new k-n secret sharing visual cryptographic scheme for black and white images in which encryption of the image is done by using Random Number generator.
