In the present advancing technology, data transmission of different multimedia like sensitive images, video, text is very important and security plays a dominant role in the fields of medical, commercial and military fields. During the transmission security of the information is required otherwise it can be accessed or hacked by the unauthorized person. Today as the ability of the network rapidly increasing, most of the data is transmitted in the form of images. Many methods like Cryptography and Steganography are developed to encrypt this kind of images which contained the data. In this paper a modified Hill cipher encryption technique has been proposed which uses an involutory key matrix. The scheme is a fast encryption scheme which overcomes problems of encrypting the images with homogeneous background.
