Since the dawn of written communication people have been concerned with both obscuring the contents of communication (cryptography) and obscuring the fact that communication is taking place (steganography). As a result of the digitization of communication, new Steganographic approaches, protocols and applications have been developed. In this paper, information about the Steganographic methods and tools that are used to hide important data in digital media are presented. At the same time, different aspects of these tools such as used methods, types of hidden data and cover media are examined.
