Principle of 2D curve steganography

Embodiments of this paper include the study of steganography as a technique of hiding images. Steganography is one of the methods of secret communication that usually hides the existence of hidden message. It can be defined as the study of invisible communication that usually deals with the ways of hiding the existence of the communicated message. The hidden message may be text, image, audio and video. A two dimensional curve is taken as the stego key to find redundancy in a digital image and a secret message is embedded in it. The approach is to hide the message in such a way that no suspicion is raised.
