## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. provisional application No. 60/781,057, filed on Mar. 10, 2006, which is herein incorporated by reference in its entirety.


BACKGROUND OF THE INVENTION
This invention relates generally to personnel screening systems, and more particularly to, an integrated passenger identity verification and screening kiosk.
The Transportation Security Administration (TSA) has recently mandated more stringent inspection procedures to be implemented by the travel industry to reduce the possibility of passengers boarding a carrier such as a plane, for example, carrying concealed weapons, explosives, or other contraband. To facilitate preventing passengers boarding a plane carrying concealed weapons, explosives, etc., the TSA requires that all passengers be screened prior to boarding the aircraft.
For example, passengers arriving at the airport terminal first submit to a manual verification process that generally includes presenting their boarding pass and a form of identification such as a driver's license or passport, for example, to security personnel. The security personnel then manually verify that the passenger has a valid boarding pass, the name on the identification corresponds to the name on the boarding pass, and that the picture on the license or passport corresponds to the passenger presenting the license and boarding pass to the security personnel.
After the manual verification process is completed, the passenger is requested to walk through a metal detector to ensure that the passenger is not carrying any concealed weapons. While the metal detector is reasonably effective at detecting specific quantities of metal, the metal detector can not distinguish between a possible weapon or other non-threatening items such as shoes that may include metallic portions. As a result, security personnel frequently request that passengers remove their shoes and place their shoes into the baggage screening system such that security personnel can visually verify the metallic object prior to the passenger boarding the plane and to also ascertain whether the shoes may conceal any explosive material or devices. Passengers are also asked to remove coats and jackets, passing them through the baggage screening system. This has the effect of making it easier for checkpoint personnel to observe possible concealed objects, such as explosives, under their remaining clothes, which are now less bulky and thus less likely to obscure the presence of concealed items.
As such, at least one known airport screening system relies on manual observations to verify the identity of the passenger and also utilizes electronic scanners and metal detectors to ascertain whether the passenger or the luggage includes any weapons or explosives. Moreover, each passenger is subjected to the same level of screening without regard to the threat that may be posed by the passenger. As a result, the known system is time-consuming for the passengers, and does not alert the security personnel when a low threat passenger or high threat passenger is being screened such that the security personnel may either increase or decrease the level of screening that the passenger or the passenger's personal effects are subjected to.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a simplified schematic illustration of an exemplary passenger identification and screening system 10. FIG. 2 is a perspective view of a portion of the passenger identification and screening system 10 shown in FIG. 1. FIG. 3 is a front view of a portion of the kiosk shown in FIG. 2. In the exemplary embodiment, system 10 includes a first subsystem 12 that includes at least a passenger verification system 14 and a passenger screening system 16, and a second subsystem 18 that includes at least a passenger verification system 20. In the exemplary embodiment, first subsystem 12 and second subsystem 18 are each installed in a standalone kiosk. Optionally, either first subsystem 12 and/or second subsystem 18 may be installed within a wall for example.
In the exemplary embodiment, system 10 includes a plurality of first subsystems 12 that are communicatively coupled to at least one subsystem 18, preferably a plurality of subsystems 18, via a communications bus 24 that is coupled between first and second subsystems 12 and 18. Each first and second subsystem 12 and 18 includes a computer 26 and 28 respectively, that enable a passenger or operator to input commands or receive biometric data from the operator and allow outputs generated by subsystems 12 and 18 to be delivered to a database computer 19 via communications bus 24. The information may then be utilized by other computer systems 21 for data analysis or utilized by an operator of any one of the computers within systems 21. In one embodiment, subsystems 12 and 18 are each hardwired to database computer 19. In another embodiment, subsystems 12 and 18 are each communicatively coupled to database computer 19 using a local area network or an internet connection.
As shown in FIG. 2, subsystem 12 is housed in a first kiosk 40 and subsystem 18 is housed within a second kiosk 42. In the exemplary embodiment, each respective kiosk 40 and 42 include a respective computer 26 and 28 that are each housed within kiosk 40 and 42, respectively. As such, kiosk 40 includes a passenger prescreening capability that will be discussed later herein. In the exemplary embodiment, kiosk 40 is positioned proximate to the location near the agent who validates a passenger's photo ID with the name on the boarding pass. This is sometimes at the entrance of the security queue or optionally at the exit of the security queue. Whereas, kiosk 42 is preferentially located at the divest area of the security lane, e.g. at the entrance to the metal detector and x-ray machine.
In the exemplary embodiment, passenger verification and/or tracking systems 14 and 20 may each be implemented utilizing a boarding pass scanner 50 that includes a bar code reader system 52 that is configured to read a bar code that is printed on each respective ticket presented by the operator or passenger. In another embodiment, passenger verification systems 14 and 20 may each be implemented utilizing a radio frequency identification device (RFID) that may be attached to or integrated with the boarding pass to enable the boarding pass scanner 50 to read the identification code stored within the RFID tag. During use, RFID tags receive and respond to radio frequency (RF) signals to provide information, for example, related to the boarding pass to which the RFID tag is attached. For example, modulators of the RFID tags may transmit back a signal using a transmitter or reflect back a signal to an RFID reader, i.e. boarding pass scanner 50. In another embodiment, at least one of passenger verification systems 14 and/or 20 may each be implemented utilizing a biometric means 56 such as, but not limited to, an iris scan device, a fingerprint scan device, a facial image recognition system, and/or a voice recognition system. In another embodiment, passenger verification systems 14 and 20 may each be implemented utilizing a card reader system 54 whereby passenger information may be encoded on a magnetic strip, optical read codes, an RF-read memory chip, or other embedded media onto the card. Optionally, kiosk 40 may include a printer that is configured to generate an identification ticket including the bar that is subsequently read by the second subsystem 18 housed within kiosk 42.
In the exemplary embodiment, passenger screening system 16 may be implemented utilizing a fingertip trace explosive detection system 60 that is capable of detecting minute particles of interest such as traces of narcotics, explosives, and other contraband on the passenger's finger or hand for example. In the exemplary embodiment, detection system 60 is located proximate to boarding pass scanner 50 such that as the passenger passes the boarding pass through scanner 50 at least a portion of the passenger's hand approximately simultaneously passes over detection system 60. Optionally, the passenger is prompted to press a button to activate detection system 60 such that trace materials on the finger surface are collected and then analyzed by detection system 60.
In the exemplary embodiment, trace explosive detection system 60 includes an ion trap mobility spectrometer 62 that is utilized to determine whether any substantially minute particles of interest such as traces of narcotics, explosives, and other contraband is found on the passenger's finger. For example, the ion trap mobility spectrometer 62 is preferentially useful in identifying trace explosives or other contraband on a passenger's finger that may be indicative of the passenger recently manipulating explosives or other contraband and as such does not require imaging or localization.
In the exemplary embodiment, all the data or information submitted by the passenger into the first subsystem 12 and or automatically collected by the first subsystem 12 is stored within a database, e.g. within database computer 19, that is accessible between subsystems 12 and 18 via communications link 24. For example, first subsystem 12 may combine the ticket/boarding pass information generated by passenger verification system 14 and the explosive detection results generated by passenger screening system 16 into a computer 26 housed within kiosk 40. The combined information is then transmitted to database computer 19 via communications link 24.
Second subsystem 18 is then utilized to retrieve the passenger data transmitted by first subsystem 12. More specifically, the information is retrieved when the passenger arrives at the security-screening lane via kiosk 42. In the exemplary embodiment, the first passenger verification and/or tracking systems means utilized by the passenger to self-initiate at first kiosk 40 is also utilized by kiosk 42 to verify the information. For example, if the passenger utilizes boarding pass scanner 50 to verify his identity, second subsystem 18 includes a comparable boarding pass scanner to re-verify the identity of the passenger at the second kiosk 42. Optionally, if the passenger's identity was verified using other means, for example, the iris scan, facial image recognition system, hand scan, voice scan, etc., then second kiosk 42 includes similar means to reverify the identity of the passenger.
Once the identity of the passenger has be reverified by second subsystem 18, second subsystem 18 utilizes the results from the passenger screening system 16 sent from the first subsystem 12 to select an appropriate passenger screening level for the passenger at the security screening lane. For example, if the results obtained by fingertip trace explosive detection system 60 in the first subsystem 12 is negative, security personnel may choose to have the passenger traverse a metal detector prior to boarding the aircraft for example. However, if the results obtained by fingertip trace explosive detection system 60 in the first subsystem 12 is positive, security personnel may opt to perform a more thorough inspection of the passenger prior to the passenger boarding the aircraft. For example, security personnel may choose to have the passenger remove his shoes and other clothing such as coats and subject these articles to a quadrupole resonance (QR) detection system. Moreover, security personnel may choose to pat down or utilize a metal detecting wand on the passenger to ensure that the passenger is not concealing any explosives or other contraband. As a result, the first subsystem 12 is utilized to perform passenger verification and also to perform an initial or pre-screening on the passenger. The second subsystem 18 then utilizes the information from the first subsystem 12 to reverify the identity of the passenger and also to alert security personnel when a passenger may require further security screening.
The combined subsystems allow a passenger to self-initiate themselves to the computerized database with the explosives screening process and then have this information automatically recalled by the full security process when the passenger arrives at the security-screening lane. This configuration also allows passengers that have recently had their identity verified by a security agent to undergo a pre-screen for explosives. The screening result would be used to dynamically adjust the security level of the screening lane as necessary, allowing the overall system 10 to covertly place higher security emphasis on the appropriate passengers and thus allows a higher level of security with minimal passenger inconvenience, traffic flow restrictions and agent resource usage.
While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims.
