A method of using iris recognition to determine whether a person is authorised to pass a security check is presented. A person attempting to pass the security check is first identified by comparing a captured and digitised iris code with iris codes stored in a database of authorised persons. The iris code for an identified person is then compared with all earlier recorded iris codes for that person. If there is an exact match, the identified iris code is deemed irregular since the probability of obtaining an exact match is significantly low. As a result, either further identifying information is requested or access to resources or systems is denied to the person. The system therefore prevents an eavesdropper who exactly copies a previous digital signature gaining passage through the security check, whilst the chance of an authorised person being denied access is reduced.
