A taxonomy of biometric methods

In this paper we shall introduce a taxonomy of biometric methods continuing thereby our previous research on selected segments of biometrics. We show how our previously developed systematization and categorization of biometric methods, characteristics and models can be extended by building upon an open ontology of biometrics. The developed taxonomy inherits its openness and extendibility as well as its consistency from the systematization, adding new insights at the same time. We add a new dimension, namely biometric samples, to our previous framework built upon biometric characteristics as well as the general biometric system developed by Wayman and extended in our research.
