Implementation of Audio Steganogarphy Using C#

Audio steganography is focused in hiding secret information in an innocent cover audio file or signal securely and strongly. Communication security and robustness are vital for transmitting important information to authorized entities, while denying access to not permitted ones. By embedding secret information using an audio signal as a cover medium, the very existence of secret information is hidden away during communication. This is a serious and vital issue in some applications such as battlefield communications and banking transactions. In a computer-based audio steganography system, secret messages are embedded in digital sound. The secret message is embedded by slightly altering the binary sequence of a sound file. Existing audio steganography software can embed messages in WAV, AU, and even MP3 sound files.
