摘　　要：论文提出了一种新颖的、利用音频水印技术将一幅数字图像嵌入音乐中的算法。该算法在保持载体音乐音质基本无损的条件下,实现了图像完好地嵌入和提取。该算法的核心思想是利用音频水印技术的特性来实现上述目标,其中具体用到了音频的自动分段技术和倒谱分析技术。实验结果表明,该算法具有较好的透明性,能够成功地提取出嵌入的图像水印信息;同时,对M P3压缩、低通滤波、白噪声等同步攻击有较强的鲁棒性。This paper proposes a novel method which solves the problem of image embedding into a fragment of audio. The proposed method seems to work well on embedding and extracting image from a fragment of audio without degrading the quality. It is also worth noting that the proposed method is based on the techniques of both auto-segmentation of audio and cestrum analysis. Experimental results show that the algorithm has good transparency and we succeed in detecting the embedded binary image, and the proposed method is robust to against some kinds of synchronization attacks such as MP3 compression, filter, white noise etc.
