摘要

目前，因特网上常用的MP3 (mpeg1层3)通常会去掉嵌入水印的听不见的信号分量。本文提出了一种在音频信号中嵌入水印的方法，该方法对MP3压缩具有鲁棒性，并能根据人的听觉能力保持声音。由于MP3是一种有损压缩技术，它对信号的不可听频率范围进行了裁剪，因此不能在不可听信号范围内嵌入水印。在该方法中，我们选择声压级较小的可听频率范围作为水印嵌入频率范围。该方法使嵌入的水印对MP3具有较强的鲁棒性，并且人类不会将水印数据识别为噪声。此外，我们还尝试使用彩色图像作为水印，以便于声明所有权。我们用流行歌曲进行了实验，结果令人满意。

Audio watermarking for Internet

Nowadays the MP3 (MPEG 1 layer 3) normally used in the Internet crops the inaudible signal components that watermarks are often embedded. This paper proposes a method to embed a watermark in the audio signal, which is robust against the MP3 compression, and the sound is maintained according to the human audio ability. Since MP3 is a lossy compression technique that crops the inaudible frequency ranges of signal, we can not embed the watermark in the inaudible signal ranges. In this method, we select the audible frequency ranges with small sound pressure level as watermark embedding frequency range. By this technique the embedded watermark is robust against MP3, and the human will not recognize the watermark data as noise. In addition, we try to utilize the color image as the watermark that is convenient to claim the ownership. We performed the experiments with the popular songs and the results are satisfied.
