摘　　要：基于生物特征识别的身份认证技术已经应用于多个领域,然而单一的生物特征有各自的优缺点,为了提高身份认证的安全性和鲁棒性,对多生物特征进行融合便成为了身份认证技术新的研究方向。将指纹识别和声纹识别通过加权融合的方法在匹配层进行融合,实验结果表明,融合系统的等错误率（EER）比指纹识别和声纹识别提高了0.3%~0.4%,证明了融合系统识别率有所提高。Identification verification based on biometric feature has been used in many fields,but the single biometric feature have their own advantages and disadvantages. In order to improve the security and robustness of identification verification,multi- biometric fusion has become the identification verification technology new research direction. This paper uses the method of weighted fusion with fingerprint and voiceprint in matching layer. The record of experiment shows that the equal error rate（ EER） of fusion system increases 0. 3% ~ 0. 4% compared to fingerprint recognition and voiceprint recognition. It proves fusion system＇s effectiveness.
