FINGER PRINT SYSTEM

The problems with finger print system

Finger prints can be easily copied.

Wrong result if the finger is dirty.

False positives. If the software is not sufficiently sophisticated

concerns over hygiene.

Not everyone would like to put their fingers on a sensor touched by

others.

FACIAL BIOMETRICS

These are susceptible to environmental changes such as lighting.

With age too, facial recognition deteriorates.

Changes in appearance with the use of cosmetics, earrings, hair, etc,

can give wrong readings too.

It's estimated there's a 5% drop in accuracy per year due to aging .

IRIS SCANNING

The problems with facial biometrics system

Many commercial Iris scanners can be easily fooled by a high

quality image of an iris or face in place of the real thing.

The accuracy of scanners can be affected by changes in lighting.

Iris scanners are significantly more expensive than some other forms

of biometrics.

Iris recognition is very difficult to perform at a distance larger than a few

meters.

Palm vein authentication device uses blood vessel patterns as a personal

identifying factor.

Blood vessel patterns are unique to every individual. Even the vein patterns

on each hand are different.

Palm has to be

positioned3-8 cm over the

sensor

Sensor emits near

infrared

beam to the palm

Oxygen reduced blood

within the veins absorbsthe near infrared light

The sensors wide angular near

infrared camera takes a rawimage of the palm vein pattern

The sensors template library

SW changes the raw imageinto template data

The generated template

can be stored in either adatabase

WHY VEINS ARE CHOSEN..

When near-infrared light passes, deoxygenated hemoglobin

in the blood flowing through the veins absorbs near-infrared rays,

causing it to be visible as black regions to the scanner.

Arteries and capillaries, whose blood contains oxygenated hemoglobin,

which does not absorb near-infrared light, are invisible to the sensor,

hence VEINS are chosen.

HOW SECURE IS THE TECHNOLOGY?HOW SECURE IS THE TECHNOLOGY?

On the basis of testing the technology on more than 70,000 individuals,

Fujitsu declared that the new system had a false rejection rate of 0.01%

(i.e., only one out of 10,000 scans were incorrect denials for access).

And a false acceptance rate of less than 0.00008% (i.e., incorrect approval

for access in one in over a million scans).

And if you registered your profile as a child, it'll still be recognized as you

grow, as an individual's patterns of veins are established in utero

(before birth).
