| Abstract(in English) | In this paper, we propose a randomized method and a beat-frequency method for an audio digital watermarking. The randomized method is based on a majority vote technique. It enables to enhance the detection accuracy without a serious deterioration of the sound quality by embedding watermark probabilistically and redundancy. The beat-frequency method is an algorithm to embed a high-density watermark in the audio by using the beat-frequency which is hard for human to perceive. We examine the performance of the proposed methods by simulations and experiments. |
