Abstract

Systems and methods and an example method including storing, in an access control memory of an access control computer system a set of access control identity records, receiving from an individual a proffered biographic information, and comparing the proffered biographic information to the access control identity records. In response to the comparing indicating a subset of than one access control identity records having biographic information having similarity to the proffered biographic information exceeding a threshold, generating and sending to a central resource computer system a biometric comparison request. The request includes the proffered biographic information of the persons, an indication of the biometric information of the person, and indication of biographic information in the identity records in the subset. A response is received from the central resource computer indicating whether a central resource identity record includes both a matching identity record biographic information and a matching identity record biometric information.
