基于基音延迟隐写的移动语音信道数据传输
Date Communication over Mobile Voice Channel Based on Pitch Delay Steganography
摘要
Abstract
In view of the security problem of end-to-end data transmission in mobile communication,this study proposes a message transmission method based on pitch delay steganography used for mobile voice channel,which hides the intended data in the voice signal.The algorithm uses secret information to control the parity charac-teristics of pitch delay value in the voiced part of speech,so as to embed data bits.The pitch delay value of the voiceless part is quantified and output by secret information to realize the embedding of steganographic information.The pitch delay change caused by embedding does not cause serious degradation of the original speech quality,so it is difficult for the outside world to detect hidden data information when transmitting speech signals.This algorithm can ensure the security and privacy of end-to-end information transmission.The simulation results show that the transmission rate of secret information can reach 200 bit·s-1 and the accuracy rate is about 94%.关键词
