FINGER PRINT SYSTEMThe 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 BIOMETRICSThe problems with facial biometrics system …• 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.• Its estimated theres a 5% drop in accuracy per year due to aging.
IRIS SCANNINGThe 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 personalidentifying factor.Blood vessel patterns are unique to every individual. Even the vein patternson each hand are different.

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, itll still be recognized as you grow, as an individuals patterns of veins are established in utero (before birth).
