Abstract
Achieving resistance to synchronization attacks on audio watermarking is a challenging task. Available synchronization methods based on local features utilize sample alignments. The local features vanish easily after operation, hindering resynchronization. This study proposes a new audio watermarking method that divides frames adaptively; it is based on the global characteristics of the frame and achieves indirect synchronization by employing a corresponding frame sequence number. The experimental results reveal that the proposed scheme exhibits effective robustness against conventional signal processing manipulation and synchronization attack processes such as jittering, time scale modification, and pitch shift modification.
