| 摘 要： | 提出一种以wav格式音频文件作为载体,根据人耳的听觉心理模型,在整数小波包域上自适应的嵌入秘密信息.它不改变载体文件的大小,同时具有良好的透明度,又能够避开人们对声音图谱的视觉攻击,并达到了很高的嵌入容量.

| Abstract: | In this paper,we put forward an adaptive embedded secret information in the integral wavelet bag region,which is carried by audio file of wave format and based on psychological model of audition.It does not change the size of carrier file and it has favorable transparency.Moreover it can avoid visual attack of audio map and get higher embedded capacity. |
