KEY BASED STEGANOGRAPHY IN A GRAY LEVEL IMAGE INVOLVING PERMUTATION AND XOR OPERATION

Abstract

In this paper, we have developed a procedure for the steganography of a plaintext in a gray level image. This procedure is totally based on a key. The plaintext is modified by permuting with the key and by performing the XOR operation with the key. The modified plaintext obtained in the afore mentioned manner is hidden in the image by taking the help of the key. The process adopted in this investigation is found to be quite interesting as the original image has practically no change even when a long plaintext is introduced into the image.
