Multimodal biometric fusion using data quality information

Prior studies of multimodal biometric fusion have shown that it can improve performance over use of a single unimodal biometric. The well-known multimodal methods do not consider the quality information of the data used when combining the results from different matchers. In addition to examining these well-known fusion methods, we introduce novel methods of fusion which combine face and fingerprint biometric results using fingerprint data quality information. We show that multimodal biometric fusion using data quality information outperforms standard multimodal results and unimodal systems.
