首先分别讨论了语音MFCC特征信息提取算法和AES密码标准算法
最后实现了一个基于AES加密的高安全性声纹特征身份鉴定系统
本文创新性地提出了对语音感知特征信息进行加密以保证声纹特征身份鉴定系统安全性的方法
) 摘要: 生物特征识别自身的安全性在很大程度上依赖于生物特征数据的安全性
本系统中存储的语音感知特征信息的安全性得到了充分保障
) Abstract: The 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
