1. Biometrics refers to the automatic identification of a
person based on his/her physiological or behavioral characteristics
. DEFINITIONOF BIOMETRICS
2. 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.
3. 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.
5. 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).
6. Facial Recognition 1. Capture image 2. Find face in image 3.
Extract features (store template) 4. Compare templates 5. Declare
matches
7. Hand or finger geometry is an automated measurement of many
dimensions of the hand and fingers. Hand Geometry
8. Iris recognition Iris scanning measures the iris pattern in
the colored part of the eye.
9. Retina recognition Images back of the eye and compares blood
vessels with existing data
11. 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.
12. 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.
13. 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. Keystroke dynamics
14. Biometrics Process No Yes Biometric Data Collection
Transmission Quality Sufficient? Yes Template Match Signal
Processing, Feature Extraction, Representation Database Generate
Template Decision Confidence? new biometric sample is requested
No
16. Disadvantages of Biometrics 1. Costly 2. Facial imaging can
also hinder accurate identifications.
17. 3. Missing body part problem. 4. The scanning of eye is
fearful. 5. The nervousness that people feel about the scanners
identification
18. 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
