PALM VEIN TECHNOLOGY YOUR HAND IS THE KEY
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.
The problems with facial biometrics system …
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
PALM VEIN AUTHENTICATION
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).
