Steganography is the act of hiding a message inside another message in such a way that can only be detected by its intended recipient. Naturally, there are security agents who would like to fight these data hiding systems by steganalysis, i. e. discovering covered messages and rendering them useless. There is currently no steganography system which can resist all steganalysis attacks. In this paper we propose an optimal GA evolutionary process to make an optimized steganographic encoding on an audio file in addition to Bitmap images. Our steganography step is based on our tool StegGen, which is designed using LSB color cycle scheme for images and now it enhanced for audio steganography using substitution techniques.
