Steganography is the art of hiding information innocuous looking objects like images, files etc. This paper explains Steganography, various techniques of Steganography and compares them. The focus of this paper is image steganography. This paper evaluates the different algorithms for digital image steganography both in the spatial and transform domain like F5, Pixel Indicator Technique, OPAP, LSB substitution etc. It compares those algorithms in terms of speed, accuracy and security and suggests some possible future research directions.

Keywords: Steganography, LSB substitution, F5, OPAP, Pixel Indicator Technique
