Template ageing in non-minutiae fingerprint recognition

This study uses non-minutiae fingerprint recognition methods to confirm earlier results on the existence of fingerprint template ageing. We performed the experiments on datasets including a time-span of 4 years. The acquisition was performed by using three different commercial off-the-shelf optical fingerprint sensors. Furthermore, we compared the results of those non-minutiae experiments to investigations performed by a traditional minutiae based approach. The analysis exhibits that there are very similar effects in terms of fingerprint template ageing detectable for all considered recognition methods.
