WHAT IS BIOMETRICS?Automated method

Pattern recognition system

Specific physiological or behavioral characteristics

WHY USE IT?Traditional methods involving passwords and PIN numbers

Biometrics highest level of security

The hardware captures the salient human characteristic

The software interprets the resulting data and determines acceptability.

HOW IT WORKS

FINGER PRINTOldest form of Biometrics

Highly Reliable

Uses distinctive features of fingers

FINGERPRINT Finger-scan biometrics is based on the distinctive characteristics of the human fingerprint A fingerprint image is read from a capture device Features are extracted from the image A template is created for comparison

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 PROPERTIESHigh degree of RandomnessNo two Iris are alikeStable in a persons lifeDoesn't vary with changes

BIOMETRIC PERFORMANCEFAR 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 PERFORMANCEFRR

The FRR is the probability that are not authenticated to access your account.

A low FRR is required when convenience is the important factor

FINGERPRINT PERFORMANCEFAR - As low as 1 in 1,000,00

FRR around 4%

IRIS PERFORMANCEFAR - As low as 1 in 1,000,000

FRR around 2%
