扩展LSB隐藏算法

In this paper, we present a novel high bit rate LSB % audio watermarking method. The basic idea of the % proposed LSB algorithm is watermark embedding that % causes minimal 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 or MPEG % compression. Listening tests showed that the perceptual % quality of watermarked audio is higher in the case of the % proposed method than in the standard LSB method.
