A brief description about biometric technology that are presently using in the society

2.  Biometrics refers to the automatic
identification of a person based on his/her
physiological or behavioral characteristics .
DEFINITIONOF BIOMETRICS

3. Biometrics History
• The term "biometrics" is derived from the Greek words
“bio” which means “life” and “metric” means “to
measure”.
• The first known example of biometrics in practice was a
form of finger printing being used in China in the 14th
century.
• In the 1890s, 'Bertillonage', created a method of bodily
measurement with the criminals who repeated the crimes
with different names and looks.
• After this, finger printing, which was developed by
Richard Edward Henry of Scotland Yard.

4. Biometric importance
• The security is needed in every place.
• Alleviate the existing problems, Like those
which can be taken, stolen, borrowed or even
forgotten.
• Improves convenience, security, and privacy.
• The first and most critical link in the security
chain.
• presented to counteract security threats.

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

9.  Hand or finger geometry is an automated
measurement of many dimensions of the hand
and fingers.
Hand Geometry

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 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.

17. Advantagesof biometrics
1. Uniqueness
2. Universality
3. Permanence
4. Measurability
5. User friendliness
6. Accuracy
7. Comfort

18. Disadvantages of Biometrics
1. Costly
2. Facial imaging can also hinder accurate
identifications.

19. 3. Missing body part problem.
4. The scanning of eye is fearful.
5. The nervousness that people feel about the
scanners identification

20. FutureProspects
• Biometry is one of the most promising and life-altering
technologies in existence today. It is all set to change the way
we live in the future. Some of the emerging biometrics
technologies in the near future are:
1)Ear shape identification.
2)Body odor identification.
3)Body salinity identification.
4)EEG Fingerprint
5)DNA matching
