A wavelet based audio steganography system

Abstract: Steganography is the art of information hiding in ways that prevent its detection. A message in cipher text may raise suspision, while an invisible message will not. Digital steganography uses a host data or message, known as a ''container'' or ''cover'' to hide another data or message called ''secret'' in it. An Image in audio steganography system had been proposed in this thesis in order to embed a secret image data in audio data. One embedding method is implemented in the proposed system (Least Significant Bit in time domain, and transform domain Discrete Wavelet Transform).
