Biometrics refers to the automatic identification of a person based on physiological or behavioral characteristics. Passwords, PINs, and keys are not very reliable for identification since they can be forgotten, shared, stolen, or easily guessed. Biometric identification uses unique physical traits like fingerprints, iris scans, voice recognition, or hand geometry that cannot be lost or shared to reliably identify individuals. As biometric technology advances, it may replace traditional identification methods and provide more secure access to sensitive information, banking, government systems, and commercial applications.

3. DEFINATION OF BIOMETRICS
The Term Biometric Comes From The Greek Words
Bios (Life) And Metrikos (Measure).
Biometrics refers to the automatic identification of
a person based on his or her physiological or
behavioral characteristics.
Comparison takes place in Real-Time.

4. WHY BIOMETRIC ?
 Passwords are not reliable.
 Too many
 Can be stolen
 Forgotten
 Shared
 Many passwords
 easy to guessPIN
 Can be duplicatedPIN
 can be Lost or
 stolenPIN a weak link(Writing the PIN on the card)
 Protect Sensitive
 Information
 Banking
 MedicalCommercial- Government

8. BIOMETRIC CHARACTERISTICS

9. FINGERPRINT RECOGNITION
Fingerprint Recognition is the identification by
using patterns of an individual's fingertips
which are unique to that individual.

10. FACIAL RECOGNITION

11. PHYSICAL BIOMETRICS

12. HAND GEOMETYRY
Hand or finger geometry is an automated
measurement of many dimensions of the hand
and fingers.

14. IRIS RECOGNITION
Iris scanning measures the iris pattern in the colored
part of the eye.

15. RETINA RECOGNITION
Images back of the eye and compares blood vessels
with existing data.

17. 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.

18. 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".

19. 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.

23. 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.
