A method and system for securing, protecting and controlling defined areas by managing access points for entering and exiting vehicles or mobile entities, and matching entering vehicle or mobile entity identification information with exiting identification information. This may include obtaining and storing a unique onboard signature and/or physical characteristics from entering vehicles or mobile entities for matching with the identity information obtained from exiting vehicles or mobile entities. In addition a paper or electronic Ticket/Tag may be encoded with the entering identification information and issued to an agent of the entering vehicle or mobile entity for later presentation at exiting, whereby a three-way matching of exiting, entering, and Ticket/Tag information must be satisfied for the vehicle or mobile entity to be released from the controlled area.
