Abstract:
Steganography is the art of secret communication. Its purpose is to hide the very presence of communication as opposed to cryptography whose goal is to make communication unintelligible to those who do not possess the right keys. The research work in this paper shows that most of the steganographic systems proposed during the past decades usually substitute the insignificant parts of the image with the secret message. However, these systems don’t pay attention to these parts, and the original image is distorted by some small amount of noise due the data embedding itself. This noise could reveal the existence of secret message and hence change the statistical profile of the cover image significantly. A simple attack such as Laplace filtering can exploit this fact and make the system detectable by the eavesdropper. In attempt to minimize the error introduced due to hiding foreign message into the cover image, a genetic algorithm approach will be employed efficiently in this paper in a way that examine the embedded bits. This has the advantage that the image remains nearly unchanged.
