New approach toward data hiding using XOR for image steganography
2016
With the growth in internet usage, there is a proportional growth in security and privacy demands. In this paper, a three bit XOR steganography system for concealing messages into gray Images is projected. In this method, last three bits of pixel value offer 100 percentage of message addition. This new technique uses the XOR operation between the message and original image. If the intruder extracts the last three bits, he would not be able to find the meaning of the message as the message is in decoded form. The maximum no of bit which is to be hidden using this method is equal to the R∗C∗3, where R and C is the rows and column of the image. The time complexity is also calculated which is equal to O(1). Later on the method is analysed on the bases of PSNR, MSE, L2RAT and MAXERR. The projected technique is also matched with other similar techniques to show the superiority.
