Review paper on text and audio steganography using GA

Steganography is used to hide the secret information within a cover media in such a way that the existence of the message could not be noticeable. Here we are considering audio file as cover media and text message as secret information. The secret information is embedded in a cover media as noise as the HAS cannot detect the sound less than 20Hz or greater than 20000Hz.

Generally LSB algorithm is used to embed the secret information within a cover media. Here we are using genetic programming to increase the robustness of the data so that the secret data could not be noticeable as far as possible.
