WHAT IS BIOMETRICS
BIO-Physical or Behavioral

METRICS-To measure characteristics
Biometrics refers to the automatic
identification of a person based on his or
her physiological or behavioral
characteristics
Physical biometrics:
Fingerprint
Facial recognition/face location
Hand geometry
Iris scan
Retinal scan
Vascular patterns
Behavioral biometrics:

Speaker/voicerecognition:
Analyzing vocal behavior
Signature/handwriting:
Analyzing signature dynamics
Keystroke/patterning:
Measuring the time spacing of
typed words
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).
