摘要:We consider a digital audio watermarking system based on reverberation. Extraction procedure uses
a correlation receiver in cepstral area. Blind dereverberation attack as the most powerful method to
remove the embedding information is presented both theoretically and experimentally including also
addition noise and desynchronization attack. For a protection against such attacks are used the
salient points and an addition of short pulses placed in appropriated time interval.
Our experiments with the modificated embedding algorithm showed that a quality of cover audio
signal occurs good and desynchronization attack is useless.
Application of MP3 compression to WM-ed audio files results to something increasing of the error
bit rates but they still occur acceptable and can be decreased by the use of error correction codes.
