%X An audio watermarking scheme which embedded robust and fragile watermark at the same time in lifting wavelet domain is presented. Robust watermark is embedded in the low frequency range using mean quantization. It has great robustness and imperceptibility. Fragile watermark is embedded in the high frequency range by quantizating single coefficient, when the audio signal is tampered, the watermark information will change synchronously. So it can be used for audio content integrity verification. The watermark can be extracted without the original digital audio signal. Experimental results show that robust watermark is robust to many attacks, such as MP3 compression, low pass filtering, noise addition, requantization, resampling and so on. Fragile watermark is very sensitive to thesc attacks.
