BIOMETRIC CHARACTERISTICS
PHYSIOLOGICALBEHAVIORAL
PHYSIOLOGICAL BIOMETRICS
FingerprintFacial recognition/face locationHand geometryIris scanRetina scan
FINGERPRINT RECOGNITIONA live acquisition of a persons fingerprintDots(very small ridges)Space between two temporarily divergent ridgesSpurs(a notch protruding from a ridge Bridges(small ridges joining two longer adjacent ridges ), crossovers(two ridges that crossover each other)
FACIAL RECOGNITION

HAND GEOMETRYHand or finger geometry is an measurement of many dimensions of the hand or fingers
IRIS RECOGNITIONIris 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 color
BEHAVIORAL BIOMETRICS
Speaker/voice recognitionSignature/hand writingKey stroke/patterning
SPEAKER/VOICE RECOGNITION
Voice/speaker recognition uses vocal characteristics to identify individuals using a pass-phrase
A telephone or microphone can be used as a sensor
SIGNATURE VERIFICATION
An automated method of measuring an individuals signature
This technique examines speed, direction and pressure of writing, the time that the styles is in and out of contact with the “paper”
KEYSTROKE DYNAMICSKEYSROKE DYNMAICS is an method of examining an individuals 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
APPLICATIONSPrevent unauthorized access to ATMs, cellular phones and desktop PCs etc.,
Criminal identification
In automobiles biometrics can replace keys with key less entry devices
Airport security
