摘　　要：提出了一种基于正弦模式的音频水印算法,用于解决目前音频扩频水印算法以伪随机序列作为嵌入信息的不足.并对水印在嵌入和检测过程中涉及到的关键技术进行了分析,给出了对其鲁棒性进行测试的过程和结果。结果表明,此算法具有水印易于生成和检测,实现简单,且对宿主信号影响小以及鲁棒性好等优点。In order to solve the problem of present audio spread-spectrum watermark arithmetic based on fake random sequence; this paper gives a method of audio spread-spectrum watermark arithmetic based on sine mode. The paper gives the analysis for key technique of watermark inlay and detection,and gives the processes and results for robust detection. The arithmetic that based on sine mode has been proved to have advantages as below： being apt to build and detect watermark, being realize simply, being a little influence to host signal, being fine robust, etc.
