Abstract
A novel method of transparent data concealment in audio-streams is discussed. The proposed system makes use of sub-band coding, least significant bit coding (LSB) and a pseudo-random bit stream generator (PRBS). A maximum of about 6% of the audio file can be used to hide data transparently with no perceptible distortion. A solution to solve the positive bias problem that is inherent in LSB encoding is also presented.
