摘要：

A watermark embedding system based on audio perceptual masking is realized and a watermark detection system using pre-processing technology is brought forward. Watermark can be detected from watermarked audio without original audio by using this method. The results show that this embedding and detecting method is robust, and on the premise of not affecting the hearing quality, it can resist those attacks such as MPEG compressing, filtering and adding white noise.
