An Enhanced Method for Data Hiding using 2-Bit XOR in Image Steganography

As we all know security is needed when we want to send data over any medium so this requires a secure medium to send data. That’s why steganography comes in mind whose aim is to send data securely without knowing of any hacker. In this paper, a new technique is projected whose aim is to keep secrete communication intact. The proposed method blends the advantage of 2 bit LSB and XOR operation. In this, first we are XORing the 8th, 1st bit of data and 7th, 2nd bit of data after this two bit are obtained. These obtained bits are replaced at the LSB position. However, with some way, any person get know about hidden message and it takes the LSB position bit then there are no chances of getting message as it is not the actual message. An experiment was performed with different dataset of images. Furthermore, it was observed that the proposed method promises good result as the PSNR and MSE are good. When the method was compared with other existing methods, it shows enhancement in the imperceptibility and message capacity. Keyword Steganography, XOR, Information Hiding, LSB
