Biometrics is the science and technology of measuring and analyzing biological data of human body, extracting a feature set from the acquired data, and comparing this set against to the template set in the database. In literature survey experimental studies show that Unimodal biometric systems had many disadvantages regarding performance and accuracy. Multimodal biometric systems perform better than unimodal biometric systems. In biometric system physical or behavioral traits are used. A multimodal biometric identification system aims to fuse two or more physical or behavioral traits. It is used in order to improve the accuracy. The fusion of multiple biometrics helps to minimize the system error rates. This paper presents an overview of multimodal biometrics. This includes block diagram of multimodal biometrics, module of multimodal biometric system, different levels of fusion in multimodal biometrics.

Keywords: Biometrics, Multimodal Biometrics, unimodal, Fusion, Authentication

Article published in International Journal of Current  Engineering  and Technology, Vol.4,No.1 (Feb- 2014)
