Cryptography of a Binary Image using a Modified Hill Cipher

Abstract

In this paper, we have used a modified Hill cipher for encrypting a binary image. Here, we have illustrated the process of encryption by considering a couple of examples. The security of the image is totally achieved, as the encrypted version of the image, does not reveal any feature of the original image.
