SECURITY APPARATUS AND METHOD

摘要

In a method of using iris recognition to determine whether a person is authorised to pass a security check, the person is first identified by comparing a captured and digitised iris code with iris codes stored in a database of iris codes for authorised persons. Then, the iris code for an identified person is compared with all previously recorded iris codes for that person. If there is an exact match, the identified iris code is deemed irregular since the changes of obtaining an exact match are significantly low. As a result, either further identifying information is requested or access to resources or systems is denied to the person.
