Abstract
This invention discloses a biometric method eliciting a migrating biometric characteristic from individuals, the method including storing at least first and second templates of at least one migrating biometric characteristic for each of a population of individuals, the first template being a reference sample of an individual's biometric characteristic and the second template being initially derived from the first template, and comparing an individual's first and second templates to a fresh sample provided by the individual and, if the fresh sample is found to sufficiently resemble the first and second templates, modifying the second template to take into account differences between the reference sample and the fresh sample. A biometric system eliciting a migrating biometric characteristic from individuals is also disclosed.
