%X Semi-fragile watermarking methods aim at detecting unacceptable malicious manipulations,while allowing for acceptable regular manipulations such as lossy compression.In this paper,a semi-fragile audio watermarking algorithm for copyright protection and content authentication is proposed.The features of the proposed algorithm are as follows: 1)The original audio signal can be adaptively divided,and the watermark depth can be intelligently adjusted according to human auditory masking and local audio character;2)The copyright protection and content authentication for digital audio can he utilized simultaneously.Experimental results show that our semi-fragile audio watermarking scheme is not only inaudible and robust against various common images processing,but also fragile to malicious modification.Especially, it can detect effectively the tampered regions.
