Abstract :
De-synchronization attack is open difficult problem. TSM manipulation is a linear stretch operation in time axis, synchronization position shift along axis. Modified mean is approximate invariant under limited TSM attack, an audio watermarking algorithm is proposed by quantifying modified mean. The algorithm keeps fuzzy synchronization by inverse stretch along time axis because of having not strict synchronization point or place. The results of experience demonstrate the algorithm can resist 10% TSM and common signal process operations.
