Abstract: The multifunctional audio watermarking algorithm cannot recover the tampered region. This paper designed a multifunction audio watermarking algorithm to solve the issue. First,the original audio signal was segmented into frames,and the similar frame of per frame was computed by using the Mel frequency spectrum coefficient. The similar frames as the robust watermark were embedded into the absolute mean value of audio low-frequency wavelet coefficients by using the Torus auto-morphism.Second,the average value of the high-frequency wavelet coefficients were taken as the initial value. The authentication watermark was generated by using the logistic sequence,and the watermark was embedded into the audio signal by quantifying high-frequency coefficients method. Simulation results show that the robust watermark possesses strong robustness to resist the attacks,the fragile watermark is very sensitive to tamper,and it can localize the tampered region and tamper recovery.
