Steganography is one of the oldest methods of secure communication. It was an art at the beginning, now became a science. It aims to conceal secret messages or data inside an innocent cover. Steganalysis is the science that can detect and extract hidden data. Many steganography and steganalysis tools exist, a lot of them are free which makes it easy for anyone to use these tools. In this paper, a comparative study will be done between two widely used steganography tools (StegHide and OurSecret) and between three steganalysis tools StegSpy, StegSecret and Hidden data detector.
