How does the manner of formation influence the usefulness of biometric characteristics?
Even though the type of developmental factor does not solely determine a biometric characteristic’s usefulness, there are a few things to take into account: • pure genotypic characteristics can’t differentiate between monozygotic (identical) twins or clones • purely behavioral characteristics are, by definition, easiest to imitate • behavioral characteristics are strongly affected by external influences and the disposition of the user • normally for identification purposes, randotypic contributions are essential due to their necessity for creating absolute uniqueness
