Visual Cryptography using KN Sharing Algorithm for Colour Images

Authors(1) :-Choksi Vandana M.

Visual cryptography technique encipher the visual information in such a way, that decipher can be performed by human visual system without any complex process. Visual cryptography is a secure process for transmitting visual information but, if anyone gets access to all shares, he/she can reveal out the secret easily. In this paper a visual cryptography scheme is proposed. This technique first encrypts the secret using a symmetric key given by the user. Further, the encrypted image is divided into N different shares. These N shares can be distributed but, the end user needs only K of these shares to regenerate the original image. After piling of K shares, the original image is generated but it is still in encrypted form. The key which is used to encrypt the image originally is now required again to decrypt the image, thus providing an additional level of security. This technique is proposed for binary image, Grey scale image & colour images. Here the symmetric key used for encryption and decryption is any string (like password). Such a technique thus would be lucrative for defence and security.
