基于确认模式的多通道生物认证研究

The Research of Multi-Modal Biometrics Bases on Verification Mode

单通道生物识别技术一直存在着很多问题,它们在准确率、用户接受程度、成本等方面都有不同的缺点,而采用多通道生物认证可以提高生物认证系统的识别性能,并且适应于各自的应用场合。本文介绍了多通道生物认证技术,在单通道生物认证系统模型的基础上,给出了多通道生物认证系统模型。最后基于人脸和语音特征的多通道生物认证系统进行相关实验,实验证明多通道生物认证大大改进了以往单通道认证在识别性能和用户接受程度等方面存在的不足,提高了生物认证系统的健壮性和实用性。

Single- modal biometrics there has been a lot of questions, which at accuracy,user acceptance,cost and other aspects of disadvantage are different. The use of multi - modal biometrics can improve the recognition performance, and adapt to their respective applications. This paper introduces the multi - modal biometrics and gives a multi - modal biometrics based on biometric in single- n^el. Finally based on the characteristics of human face and voice of the multi - modal bio- metrics biology - related experiments proves that multi - modal biometrics has significantly improved the identification of the previous single- modal certification at the level of performance and the user acceptance,etc. ,and enhanced system robustness and practicality.
