摘要

The search for reliable biometrics is increasing with global security threats. A biometric must remain consistent throughout a lifetime if it is to be successful for identification purposes. The number of degrees-of-freedom that a biometric has determines its suitability with increased independent dimensions of variation providing a more discriminative biometric. The iris contains around 266 degrees-of-freedom cited which is the greatest of all facial features. However, the iris pattern is complex and the iris is dynamic, with changes in pupil size mediated via the autonomic nervous system in response to internal and external stimuli.
