Biometric Systems

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 infraredbeam to the palm

Oxygen reduced blood within the veins absorbs the near infrared light

The sensors wide angular nearinfrared camera takes a rawimage of the palm vein pattern

The sensors template library SW changes the raw image into template data

The generated template can be stored in either a database

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).
