Abstract
An iris identification system and method of identifying the identity of an animate being through iris scanning are disclosed. The system features an iris system pick-up unit including a camera for capturing iris images to create input image signals. The iris image pick-up unit is operated with a control unit that is interfaced with a data processing unit for preprocessing the input image signals into processed data. The processed data is representative of one of a plurality of parameters for iris identification selected from the group consisting of (,) the density and texture form of the iris fiber structure using a frequency transformation method, (,) pupilliary reaction, (,) the shape of the pupil, (,) autonomous nervous wreath reaction, (,) shape of the autonomous nervous wreath, (,) the existence of lacuna, (,) the location of the lacuna, and (,) the shape of the lacuna. The control unit is operable to compare processed data with parameters pre-stored in a data base that correspond to the processed data parameters to determine a match indicative of a confirmation of identity.
