Definiton of biometrics
Terms of biometrics
Biometrics characteristics
Biometrics recognition techniques
Applications
conclusion
Biometrics refers to the automatic identification of a person based on his or her physiological or behavioral characteristics .
DEFINITION OF BIOMETRICS
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
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.
