Blind cepstrum domain audio watermarking based on time energy features

The synchronization problem is a serious issue in the watermark area. It happens when losing the location of the embedded watermark when cropping, shifting and so on. Therefore the detector finds it difficult to reform the copyright information. In this paper, the proposed method combines an energy-feature basis idea in the time domain to solve the synchronization problem and achieved blind audio watermarking in the cepstrum domain. The simulation results show a high security performance against the MP3 attack and the robustness improvement of several kinds of digital distortion attacks such as pitch-shifting, and cut samples.
