Monitoring and reporting of fingerprint image quality and match accuracy for a large user application

The main objective of this paper is to present the methodology used for measuring and monitoring the quality of fingerprint database and fingerprint match performance of a large user fingerprint identification system. The Department of Homeland Security´s (DHS) biometric identification system is used as an example for this study. In addition the paper presents lessons learned during system performance testing and independent validation and verification analysis of large scale systems such as DHS´s biometric system and recommend improvements for the current test methodology.
