conclusion

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

DEFINITION OF BIOMETRICS

Biometric characteristics

1) Physiological 2) Behavioral

Physical biometrics

Fingerprint

Facial recognition/face location

Hand geometry

Iris scan

Retina scan

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).

Facial Recognition

1. Capture image

2. Find face in image

3. Extract features (store template)

4. Compare templates

5. Declare matches

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

Hand Geometry

Iris recognition

Iris scanning measures the iris pattern in the colored part of the eye,

Retina recognition

Images back of the eye and compares blood vessels with existing data

Behavioral biometrics

Speaker/voicerecognition Signature/handwriting

Keystroke/patterning

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,

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’’.

Keystroke dynamicsKeystroke dynamics is an automated method of examining an individual’s keystrokes on a keyboard.

This technology examines such dynamicsas speed and pressure, the total time taken to type particular words, and the time elapsed between hitting certain keys.

Advantages of Biometrics

• Biometrics are generally used for authentication.

• It provides higher security .e.g. Iris recognition .

• Voice Recognition works well over the telephone

• User friendly

e.g. Hand geometry recognization,

finger print recognition.

Prevent unauthorized access to ATMs, Cellular phones Desktop PCs

Criminal identification

In automobiles biometrics can replace keys with keyless entry devices

Airport security In brand new cars

APPLICATIONS

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.
