| 摘 要： | 为提高图像传输的安全性,将基于音频采样点倒置的算法用于基于语音的图像信息隐藏算法中,引入了静音检测（voice activity detection,VAD）技术筛选适宜隐藏信息的语音段,并采用Logistic混沌映射对秘密图像预处理。实验表明,该算法实现了盲提取,较大地降低了提取误码率,嵌入图像信息后的载体语音具有良好的透明性和鲁棒性。

| Abstract: | An image information hiding algorithm based on audio sample dots inversion is proposed.Voice activity detection（VAD） is adopted to choose voice sample for information hiding.Logistic chaotic map as chaotic sequence is used to process the secure image.Experiment results show that the algorithm achieves blind extracting,the bit err rate is decreased,and the speech which is embedded with secret image information has good imperceptibility,and the algorithm is strongly robust to many attacks. |
