DEFINITION OF BIOMETRICS

• The meaning of Biometrics comes from the Greek

• BIOMETRY= BIO means LIFE & METRY means TO MEASURE.

• Biometrics is the science and technology of MEASURING & ANALAYZING BIOLOGICAL DATA.

• Biometrics are automated method of recognizing a person based on a PHYSIOLOGICAL or BEHAVIORAL characteristics.

MODES OF BIOMETRICS

• Biometric system can operate in two modes.

• Identification

• Verification

IDENTIFICATION

Biometric identification compares a biometric “signature” to all the records stored in a database to determine if there is a match.

VERIFICATION

Biometric verification compares a newly-scanned biometric characteristic to a measurement previously collected from that same person to verify that individual’s identity.

BIOMETRIC CHARACTERS

• Physiological

• Behavioral

PHYSIOLOGICAL BIOMETRICS

• Fingerprint

• Facial Recognition

• Hand geometry

• Iris scan

• Retina Scan

FINGERPRINT RECOGNITION

• A live acquisition of a persons 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)

FACIAL RECOGNITION

• Capture image

• Find face in image

• Extract features (store template)

• Compare templates

• Declare matches

HAND GEOMETRY

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

IRIS RECOGNITION

• Iris scanning measures the iris pattern in the colored part of eye.

RETINA RECOGNITION

• Images back of the eye and compares blood vessels with existing data.

BEHAVIORAL BIOMETRICS

• Speaker/Voice Recognition

• Signature/Hand Writing

• 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 individuals 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 dynamic is an automated method of examining an individuals keystrokes on keyboard.

• This technology examines such dynamics as speed,

pressure and total time taken to type particular words.

VARIOUS BIOMETRIC TECHNOLOGIES

MARKET DISTRIBUTION(2007)

APPLICATIONS• Prevent unauthorized access to ATMs, cellular phones and desktop PCs

• Criminal Identification

• In automobiles biometric 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 password and keys in your bags or pockets will be things of past.
