An Audio Watermarking Detecting Improved Algorithm Based on HAS

DU Cheng-tou, WANG Rang-ding (CKC Software Lab, Ningbo University, Ningbo 315211, China)  
In the last few years, the problem of copyright protection of multimedia digital products has attracted the interest of scientists and entrepreneurs alike. The most promising solution to this challenging task seems to lie in data hiding techniques, i.e., methods for secretly and imperceptibly embedding signals of certain characteristics in the media of interest. An improved audio digital watermarking algorithm based on Garcia[3] is presented in this paper. Garcia’s algorithm can not detect watermark when watermarked audio is attacked by de-synchronization, although it is not degraded. For this problem, detecting improvement method of resisting de-synchronization dividing segmentation and pre-processing corrupted high frequency is proposed in this paper. This algorithm can effectively detect de-synchronized attack watermark by random cutting, MP3 compression, replacement and so on. The experimental results show that the proposed algorithm performances extremely surpass Garcia’s.
