摘要：Steganography is the way of hiding data in such a way that nobody except the intended receiver can detect the presence of data and retrieve it. The most widely used method used for image Steganography is LSB modification method. Although it is a simple technique, but the probability of detecting the hidden data is high since the present Steganalysis algorithms are capable enough to detect not only the alteration in image but also the secret data hidden in image. The linear plain text hidden in an image can easily be detected. In this paper we proposed a new secure method of implementing image Steganography. Instead of using a single image for Steganography, we are using two images. In this method we are hiding the data without altering the image containing the actual data. Thus it provides more security than other methods of hiding data in the image. The proposed method can also efficiently hide large amount of data which was difficult to hide in other Steganographic methods.
