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. |
