Robust watermarking of music signals by cepstrum modification
— A method of embedding a predetermined watermark in an audio signal is described for audio music copyright protection applications. The proposed technique applies the psychoacoustical masking property of the human auditory system to imperceptibly embed the watermark in the cepstral domain of a host audio signal. Embedded watermark is extracted using an oblivious detection technique without resorting to any correlation procedure. Experimental results show that the watermark is robust to bandpass filtering and additive noise at low power levels.
