Reduced distortion bit-modification for LSB audio steganography

In this paper, we present a novel high bit rate LSB audio data hiding method that reduces embedding distortion of the host audio. Using the proposed two-step algorithm, hidden bits are embedded into the higher LSB layers, resulting in increased robustness against noise addition. In addition, listening tests showed that perceptual quality of watermarked audio is higher in the case of rite proposed method than the perceptual quality obtained using the standard LSB method.
