Abstract: A system and method for securing a defined perimeter using multi-layered biometric electronic processing. The present invention provides means for authorizing objects to enter a defined perimeter, for assigning an object access rights to zones within a defined perimeter, and for monitoring and tracking objects within the defined perimeter without undue intrusion or delay. A private biometric and a public biometric are used to identify a human object to allow the human object to enter a defined perimeter. The public biometric is used monitor the movement of a human object within zones and to identify human objects that are in violation of their assigned access rights. In an air transportation system, the defined perimeter comprises all airport, airport terminals and facilities within the system.
