Encrypting secret messages prevents adversaries from obtaining sensitive information. However, an encrypted message attracts attention, which is not desired when secrets are exchanged. To conceal the secret message itself, image steganography is a technique that attempts to hide the message in images. There are several approaches that use different strategies. The most promising is SteganoGAN by Zhang et al. Their model is capable of hiding up to 4.4 bits per pixel of arbitrary data inside images while it evades detection by steganalysis tools. On the basis of SteganoGAN, the motives and the concepts of steganographic systems are expressed in this paper.
