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

4. BIOMETRIC TERMS
Recognition
Identification
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 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).

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 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’’.

15. 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.

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.
