Multimodal biometric systems use more than one biometric trait or more than one algorithm
for estimating the similarity. These systems allow using more factors for making decision.
Since, the classical binary logic and threshold comparison do not give an ideal results in
making decision, fuzzy logic is one approaches for solving this problem. This study presents
a multimodal biometric system that uses three different fingerprints with fuzzy fusion system
for making decision. The EER of fuzzy fusion based multimodal system is calculated and …
