防篡改问题论文,，一个应用程序使用可视密码方案

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印-Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection
