Abstract: Multimodal Biometrics is a combination of different biometric modalities for individual’s identification. In contemporary commercial unimodal biometric systems, most uses a single trait for authentication. So it is called unimodal system. Some of the drawbacks of unimodal biometrics such as intra- class variations, restricted degrees of freedom, spoof attacks and non-universality are eliminated by fusion based biometrics systems for unique personal identification. Various methods of fusion and data integration strategies can be utilized to combine information in multimodal systems. This paper presents a brief study on past research and development in the field of multimodal biometric technology in terms of fusion level, techniques for dimensionality reduction and normalization methods.
