We present a novel scheme that is able to combine digital watermarking and content authentication of digital audio. The embedding of additional data is performed in discrete wavelet domain. Watermark embedding is done by frequency hopping method, while the additional authentication data is hidden using the LSB modulation. The perceptual transparency is achieved using the frequency masking property of the HAS. The scheme obtains high robustness against standard watermark attacks and localizes the accurately tampered parts of the audio clip.
