Enhanced steganography using pixel pattern matching

Hiding information by embedding secret data into a redundant medium is called as steganography. However in modern times as the techniques for enforcing security have advanced, so have the methods to break them. In image steganography, the main drawback is that the pixels of the image get altered which increases the suspicions about hidden data present in it and those techniques which reduce the noise content are easier to crack. To overcome these problems, this paper proposes a technique where pixel pattern based steganography is used which searches the pixels in which the data can be hidden without altering the pixel values and stores the location of those pixels in another image. The message and the keys are encrypted for additional security.
