基于AES密码的语音感知信息加密的研究与实现

he safety of Biometrics to a great extent depends on the safety of Biometrics data; however there is not enough attention on study on safety of Biometrics data. In order to guarantee the security of voiceprint personal identification system, this paper presents innovatively encryption of perceptive characteristic information of speech. Firstly algorithm on MFCC character extraction and AES cryptogram is discussed separately, programming implementation then is given, at last a voiceprint personal identification system with high security is implemented using AES cryptogram. Experiment results show a good recognition rate. For adopting the AES cryptogram, the security of perceptive information of speech stored in this system is guaranteed.
