ABSTRACT
Envision a day when the door to a secured office building can be opened using an automated system for identification based on a person’s physical presence, although that person left his or her ID or access card on the kitchen counter at home. Imagine ticketless airline travel, whereby a person can enter the aircraft based on a positive identification verified biometrically at the gateway. Picture getting into a car, starting the engine by flipping down the driver’s visor, and glancing into the mirror and driving away, secure in the knowledge that only authorized individuals can make the vehicle operate.
