摘要
本文提出了一种基于3G通信系统的音频数字水印算法。该方法针对3G移动通信技术的需要和特点,选用3G标准下的aacPlus音频格式作为载体,通过跳频扩频方法在音频载体的频域选取水印嵌入位置,并通过直接序列扩频方法对水印信息进行处理。实验结果表明此水印方法有较高的安全性和鲁棒性。
This paper presents an audio watermarking method based on 3G communication system.The method takes aacPlus audio format as carrier to consider the demands and features of 3G,chooses watermark embedded locations in the frequency domain of the audio carrier with FHSS method and processes the watermark information with DSSS method.Experimental results show that this method has good security and robustness.
