Abstract

Integrated biometric system coherently connects multiple independent biometric systems to improve upon security and usability. But due to some involved factors the performance of overall system get degraded. This paper proposes a heuristic technique to improves the performance of fingerprint based integrated biometric system. One of the main advantage of the proposed technique is that it does not ask to modify the underline identification approach of the independent systems. The technique has been tested by constructing an integrated system with three commercial available independent biometric systems and the database used is IITK-Rural containing fingerprint images of 500 subjects collected over two sessions on three scanners. The proposed heuristics improves the equal error rate (EER) of integrated system from 21.78% to 15.67%.
