Abstract: Visual Cryptography Scheme (Vcs) Is A Procedure For Encrypting Visual Data Such As Hand-Written Text, Image, Digital Text, Captured Image Etc. In This Scheme, The Shares Are Generated By Scrambling The Pixels Of The Original Image. Further, These Shares Are Sent To Receiver For Decryption At The Receiver End. In this paper, we have proposed an automated tool that takes the binary image as an input, and generates initial shares with one pixel encryption algorithm. Further, these initial shares are encrypted using 2-pixel encryption algorithm. The encrypted shares are then sent to the receiver for decryption to obtain the initial shares. The receiver then stacks the shares to get the original image. The proposed work which is presented in the methodology is the extension of VCS algorithm.
