SECURITY ENHANCEMENT METHOD AND APPARATUS FOR IRIS RECOGNITION, USING DISTRIBUTED IRIS TEMPLATE STORAGE AND MATCHING

摘要

The present invention relates to a security enhancement method and apparatus for iris recognition, using distributed iris template storage and matching. More particularly, the present invention relates to a security enhancement method and apparatus for iris recognition, using distributed storage and matching of an iris template, the method comprising the steps of: generating an iris template from an iris image obtained through iris recognition; dividing the generated iris template into n element templates; separately storing or registering the n divided element templates in previously designated element template databases (DBs); and measuring the distance between a stored pre-registered element template and an element template for authentication so as to authenticate an iris template (one-to-one comparison), or measuring distances between a plurality of stored pre-registered element templates and an element template for identification so as to identify an iris template (one-to-many comparison).
