Proceedings of the Second International Workshop on Multimodal User Authentication, Toulouse (France)Resumen
The lack of robustness against image quality degradation
is a open issue in fingerprint verification. It has been
found in previous studies that the behavior of a fingerprint
verification system may vary depending on the quality of the
fingerprints. In this paper, we study the performance for individual
users under varying image conditions using a multisensor
database acquired with three different fingerprint
sensors. We propose a user-dependent score normalization
scheme that exploits quality information, reaching an EER
improvement of s 15% in one particular sensor. We have
also included the proposed score normalization scheme in
a multisensor fingerprint verification system that combines
the three sensors, obtaining an EER improvement of s 13%
in the best case
