DEFINITION OF BIOMETRICS
Biometrics refers to the automatic identification
of a person based on his or her physiological or
behavioral characteristics .
4
BIOMETRIC TERMS

1. Recognition
2. Identification
3. verification

5
Biometric characteristics 1)
Physiological 2) Behavioral
6

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

7
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).

8
Facial Recognition

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

9
Hand Geometry
Hand or finger geometry is an automated
measurement of many dimensions of the hand and
fingers.
10
Iris recognition
Iris scanning measures the iris pattern in the
colored part of the eye,
11
Retina recognition Images back of the eye and
compares blood vessels with existing data
12

• Behavioral biometrics
• Speaker/voicerecognition
• Signature/handwriting
• Keystroke/patterning

13
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,
14
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.
15
Keystroke dynamics Keystroke dynamics is an
automated 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.
16
APPLICATIONS

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

17

• 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.
