WHAT IS BIOMETRICS?  Automated ed method  Automat  Automate d method





Pattern recognition system



Specific physiological or behavioral characteristics

 

WHY USE IT? 

Traditional methods involving passwords and PIN numbers



Biometrics highest level of security

BIOMETRIC SYSTEM

HOW IT  WORKS

 



The hardware captures the salient human characteristic



The software interprets the resulting data and determines acceptability.

 

FINGER PRINT 

Oldest form of Biometrics



Highly Reliable



Uses distinctive features of fingers

IRIS RECOGINITION

IRIS RECOGNITION

 

 

Pattern recognition technique

 

Identification by mathematical analysis of the random patterns.

 

Based upon the qualities of the Iris

 

 

Iris is a protected internal organ whose random texture is stable throughout life

 

IRIS PROPERTIES High gh degree of Randomness Hi No No two  two Iris are alike St Stable able in a persons life Doesn't vary with changes

 

IRIS SCAN 

Camera at close proximity



Captures photograph



Uses Infra red light to illuminate 

High resolution photograph

 

IRIS SCAN IMAGE

 

IRIS CODE Localization of inner and outer boundaries  Pattern of 512 bytes 



Complete and Compact description  More complete than features of DNA

IRIS RECOGNITION Database of millions of records  Iris code generated is compared 



Searching algorithm based on Properties

of Iris  Order of a few seconds

 

 AVIATION – IRIS DEVICES

 

BIOMETRIC PERFORMANCE FAR

  The FAR is the chance that someone other than you is granted access to your account.   Low false acceptance rate is most important when security is the priority

 

BIOMETRIC PERFORMANCE FRR

  The FRR is the probability that are not authenticated to access your account. when convenience convenience required when   A A low FRR is required is the important factor 

 

FINGERPRINT PERFORMANCE 

FAR - As low as 1 in 1,000,00



FRR –around 4%

 

IRIS PERFORMANCE 

FAR - As low as 1 in 1,000,00 1,000,000 0



FRR –around 2%

 

 APPLICATIONS Criminal identification   Prison Prison security 
