This new biometric identification method computes in each face a characteristic set of component images. or Eigenfaces. which can be used to positively identify an individual. This rapidscanning capability is superior to traditional ID cards. authorization keypads. palm readers. and most retinal scanners. Unlike conventional systems. it can scan a crowd and pick out individual faces. rather than require individuals to position themselves before a scanner. It is perfect for use at airports. border crossings. or wherever large numbers of people pass through for entry and timeconsuming identification procedures are not practical. This technology will support the counterterrorism effort the Congress * established last year. addressing one of the most pressing national security threats we face.
