BIOMETRIC SYSTEM 2/2

The hardware captures the salient human characteristic.

The software interprets the resulting data and determines acceptability.

FINGERPRINT SCANNING

It’s the acquisition and recognition of a person’s fingerprint characteristics for identification purposes.

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 degree of Randomness

No two Iris are alike

Stable 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 CODELocalization of inner and outer

boundaries

Pattern of 512 bytes

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 PERFORMANCE

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

FRR –around 4%

IRIS PERFORMANCE

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

FRR –around 2%
