A Biometric recognition system provides automatic identification of an individual based on a unique feature. Among the various biometric technologies, multimodal based authentication has gain more popularity for its accuracy and efficiency as recognition system. Unlike unimodal, multimodal biometric system incorporates two or more individual biometric trait, as a result the overall system recognition rate increases significantly. This is true even in the presence of erroneous, incomplete or missing data. This paper gives an overview of some the popular and novel research directions that have recently emerged in the biometric security domain.
