Abstract:
A system for confirming the identity of an animate being through iris scanning, comprising:a) a control unit for receiving identifier information identifying the animate being, and a data storage unit including a data base accessed by the control unit for containing predetermined personal information associated with an identifiable being for comparison with identifier information;b) an iris image pick-up unit including a camera operated by the control unit when the identifier information corresponds to the predetermined information for capturing iris images to create input image signals; andc) a data processing unit for preprocessing the input image signals into processed data;wherein said storage unit includes, for the identifiable being, at least one of a plurality of pre-stored parameters for iris identification selected from the group consisting of (1) the density and texture from of the iris fiber structure using a frequency transformation method, (2) pupillary reaction, (3) the shape of the pupil, (4) autonomous nervous wreath reaction, (5) shape of the autonomous nervous wreath, (6) the existence of lacuna, (7) the location of the lacuna, and (8) the shape of the lacuna, said control unit being operable to compare the processed data with said parameter(s) to determine if there is a match indicative of a confirmation of identity.
