An audio protection and authentication scheme is proposed. By quantizing a host audio's FFT-coefficients as masking threshold units (MTUs), two complementary watermarks are designed and embedded using our cocktail watermarking method. For audio protection, high robustness can be achieved; whereas for audio authentication, tampered regions can be detected. Both of the above mentioned goals are accomplished in an oblivious manner. Experimental results indicate that our multipurpose audio watermarking scheme is remarkably effective
