Comparative Study for Steganography Techniques

Various steganography techniques for hiding information have been created. Steganography is the art or science of hiding data in such a means that even the receiver cannot estimate the presence of the unseen data except he is responsive of the accomplishment of hiding letter. The whole awareness of steganography is to guarantee that the transferred message is fully covered; by this means make sure that the message is reachable only to the intentional receiver. Steganography generate a protected channel to exchange the top-secret information between two parties. In this project, several steganography techniques have been analyzed. The main idea of the project is to introduce an overview of image steganography to identify the requirements of a good steganography approach the terms of good approach is application depended. in general This methodology should be able to hide a secret message in an image file (cover image) and should also be able to extract the hidden information from the cover image.
