Claim:
1. A computer-implemented method for controlling access to a facility at an access control point, the method comprising: receiving, by a computer of an access control system, an image from a camera of a license plate associated with a vehicle approaching the access control point; searching, by the computer, for a record of the vehicle according to the license plate in a first data base of one or more databases logically residing in a hierarchical architecture storing one or more records of vehicles approaching the access control point, and wherein each record of the vehicle comprises the license plate, an indication of an identity for one or more individuals previously identified in the vehicle from a prior entry, a unique iris scan of the one or more previously identified individuals from a prior entry, and an indication of whether authorization was granted; searching, by the computer, when the record of the license plate is not found in the first database, remaining databases of the one or more databases that are at a higher-hierarchical level than the first database to retrieve one or more deny access records of the license plate indicating an identified problem for granting access to the vehicle, storing, by the computer, the record of the vehicle into a cache memory accessible to the computer before the vehicle reaches an iris scanner; receiving, by the computer, a scan from the iris scanner of an iris of each individual currently in the vehicle; comparing, by the computer, the scan of the iris of each individual currently in the vehicle against the unique iris scan for previous one or more individuals in the record of the vehicle; denying, by the computer, access for the vehicle responsive to determining that the one or more retrieved deny access records indicate problems have been identified; and authorizing, by the computer, access for the vehicle responsive to determining that the individuals currently in the vehicle matches the previous one or more individuals in the vehicle identified from the prior entry and upon determining that the record indicates that authorization was previously granted.
