Iris identification system and method of identifying a person throagh iris recognition

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 (1) the density and texture form of the iris fiber structure using a frequency transformation method, (2) pupilliary 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. 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.

Description

Technical field [0001] The present invention relates to an iris recognition system and a method for confirming the identity of a living body by using an iris image. In particular, the present invention relates to a method for detecting one or more identification parameters for iris recognition. These parameters are related to iris fiber structure, autonomic nerve ring (ANW) and pupil shape, as well as their spontaneous reflection of light, and iris diagram. The existence, shape and location of the dark spots of the image. Background technique [0002] The well-known iris recognition system used to identify a specific person compares the iris code of the image signal taken from the iris part of the human eye with the relevant iris information retrieved from the database to accept or reject one according to the result of the comparison. Designated person. However, this traditional iris recognition system has not yet achieved acceptable high recognition accuracy. [0003] In additio...

Problems solved by technology

However, this traditional iris recognition system has not yet reached an acceptable high recognition accuracy

[0003] In addition, because various iris recognition systems have limitations in distinguishing whether what they observe is the real iris of a living human body, it cannot be safely used in certain Some systems, such as: banking system, electronic settlement system, etc.
