FCW : August 15, 2013
BackStory 34 August 15, 2013 FCW.COM Biometrics from head to toe Agencies' use of biometrics for identity management has centered on ngerprints and iris scans, but the options do not stop there FACE Facial features or patterns are analyzed using eigenfaces or local feature analysis. Research has also shown that vein-pattern recognition can be used to identify an individual. EARS Analyzing ear shape might be as effective as facial recognition --- and the shape remains consistent as individuals age. EYES Iris recognition is the most common method, but retinal capillary patterns are also unique. And researchers see potential in periocular recognition. VOICE The tone, pitch and cadence of an individual s voice can be matched to previously authenticated recordings. HANDS/FINGERS Fingerprints are the time-honored biometric marker. Finger geometry, hand geometry and vein recognition in a nger or palm are also options. GAIT The way one walks can be observed and measured to determine identity. ODOR An individual s body chemistry provides an olfactory signal that can be identi ed by biosensors. RAPID DNA TESTING DNA, the ultimate identi er, used to take months to analyze and pro le. Now there are machines that can do the work in less than 90 minutes. SIGNATURE RECOGNITION Dynamic authentication, which tracks the speed and motions of the handwriting process, is rapidly replacing the comparison of static signatures. TYPING RECOGNITION The force, speed and rhythm with which an individual taps the keys produce a personal signature of a different sort.
