Due to the fact that biometrics, as an automatic means of human recognition, constitutes a relatively novel field of research (Jain et al., 2006), to date most efforts undertaken by the different parties involved in the development of this technology (researchers, industry, evaluators, etc.) have been mainly focused on the improvement of its performance (i.e. finding novel methods to obtain lower error rates) (Wayman et al., 2005; Cappelli et al., 2006). As a consequence, other important aspects closely related to this type of system such as the performance degradation effect known as ageing have been left partially uncovered (Jain et al., 2008).
