Steganography is an important area of research in recent years. Steganography usually deals with the ways of hiding the existence of the communicated data in such a way that it remains confidential. Steganography is used some cover media like image file, audio file, video file, text file to hide the data. In image steganography, secrecy is achieved by embedding data into cover image and generating a stego-image. Bits of information are placed in pixel values of image so that intruder cannot find out where data is hidden. There are different types of steganography techniques each have their strengths and weaknesses. In this paper, we review the different technique of Image steganography - LSB, PVD (least significant bit, pixel value differencing), PIT (pixel indicator technique), of Image steganography techniques - LSB, PVD (least significant bit, pixel value differencing), PIT (pixel indicator technique),
