Increasing Robustness of LSB Audio Steganography by Reduced Distortion LSB Coding

Abstract
Abstract: In this paper, we present a novel high bit rate LSB audio watermark-ing method that reduces embedding distortion of the host audio. Using the proposed two-step algorithm, watermark bits are embedded into 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 the proposed method than in the standard LSB method. Key Words: audio steganography, LSB coding, data hiding
