Abstract: Audio watermarking is the process of embedding special information into audio stream (original audio signal) to identify its origination. Imperceptibility and robustness are the main characteristics of watermarking. The proposed algorithm uses a blind digital audio watermarking scheme in time domain. Using the proposed algorithm, hidden bits are embedded into the higher LSB layers, resulting in increased robustness against noise addition. It is able to shift the limit for transparent data hiding in audio from the fourth LSB layer to the sixth LSB layer. It also takes advantage of the perceptual properties of human auditory system (HAS) in order to add a watermark into a host signal in a perceptually transparent manner.
