Steganography is defined as the study of covert communication. Steganography ordinarily deals with the ways of hiding. The presence of the communicated data in such a way that it remains secret. It provide secrecy between two communicating parties. In color image steganography, secrecy is achieved by embedding data into cover image and gives a stego-image. There are various types of steganography techniques each have their advantages and disadvantages. In this paper, we review the comparison between two different steganography method name as Jsteg and JMQT that are used to implement a color image steganography. In section 1st we have discussed about introduction.
