| 摘 要： | 基于扰动调制的音频数字水印方法，通过按声音掩蔽效应先对音频信号分段，并取离散小波变换的低频成分，按扰动调制技术嵌入已置乱的水印信息，解决了直接在低频成分嵌入水印信号所带来的敏感噪声问题．实验表明此方法对多种攻击具有较好的抗干扰能力．

| Abstract: | The method of audio digital watermark based on dither modulation is dedicated to the problem which a watermark directly inserted into low frequence part made out sensitive noise, being subsection for audio signal by audio mesk effect, taking low frequence part of discrete wavelet transform , and inserting into scrambling watermark by dither modulation. The experiment shows that the method has a better adaptability to attacks. |
