Abstract
Steganography means hiding a hidden payload within an apparently-innocent cover, usually an item of digital media. There is lots of literature on hiding, and detection of hiding, in images, but rather little in audio. But mp3 audio is widely transmitted on file-sharing networks and thus provides an excellent cover. One slightly old-fashioned example of mp3 steganography can be found here http://www.petitcolas.net/fabien/steganography/mp3stego/ This project is to explore and develop mp3 steganography, adapting modern image hiding techniques to the audio format and implementing hiding and extraction programs.
Prerequisites:
No course prerequisites, but this project is only suitable for students who are already familiar with the details of mp3 format and encoding, for example those who have worked on open-source audio codecs. It is NOT possible to learn the format within the time available.
