DEFINITION OF BIOMETRICS Biometrics refers to the automatic identification of a person based on his or her physiological or behavioral characteristics .

BIOMETRIC TERMS Recognition Identification verification

Biometric characteristics 1) Physiological 2) Behavioral

Physical biometrics Fingerprint Facial recognition/face location Hand geometry Iris scan Retina scan

Fingerprint recognition A live acquisition of a person’s fingerprint. Dots (very small ridges), Space between two temporarily divergent ridges), Spurs (a notch protruding from a ridge), Bridges (small ridges joining two longer adjacent ridges), crossovers (two ridges that cross each other). http://www.hhsc.state.tx.us/Consolidation/Consl_home.html. www.rediris.es/cert/doc/ unixsec/node14.html

Facial Recognition Capture image 2. Find face in image 3. Extract features (store template) 4. Compare templates 5. Declare matches

Hand Geometry Hand or finger geometry is an automated measurement of many dimensions of the hand and fingers.

Iris recognition Iris scanning measures the iris pattern in the colored part of the eye,

Retina recognition Images back of the eye and compares blood vessels with existing data

Behavioral biometrics Speaker/voicerecognition Signature/handwriting Keystroke/patterning

Speaker / Voice Recognition Voice or speaker recognition uses vocal characteristics to identify individuals using a pass-phrase. A telephone or microphone can serve as a sensor,

Signature Verification An automated method of measuring an individual’s signature. This technology examines speed,direction, and pressure of writing; the time that the stylus is in and out of contact with the “paper’’.

Keystroke dynamics Keystroke dynamics is an automated method of examining an individual’s keystrokes on a keyboard. This technology examines such dynamics as speed and pressure, the total time taken to type particular words, and the time elapsed between hitting certain keys.

APPLICATIONS Prevent unauthorized access to ATMs, Cellular phones Desktop PCs Criminal identification In automobiles biometrics can replace keys with keyless entry devices Airport security

Conclusion Biometric is an emerging area with many opportunities for growth. Possibly in the near future, you will not have to remember PINs and passwords and keys in your bags or pockets will be things of the past.
