Comparative study of image steganography techniques

This paper tend to review different steganography techniques for suppression of the information. Steganography technique is important as everyone wants to convey their message in such a way that no one could track their information. Steganography is defined as the study of indiscernible communication that usually deals with the ways in which the transmitted data can be preserved from tracking. Another technique is cryptography, which is used for protecting the transmitted information. The encryption methods of cryptography and steganography allows the user to transmit the information which is placed inside a file in plain view. Image steganography is a technique which hides secret information inside an image and conceals the existence of the communication. This will provide more security to the data to be transferred on the network.
