Biometric Systems

Finger print system Finger prints can be easily copied. 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 The 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. It's estimated there's a 5% drop in accuracy per year due to aging.

Iris Scanning The problems with Iris scanning 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 vein authentication Sensor emits near infrared beam to the palm Palm has to be positioned 3-8 cm over the sensor Oxygen reduced blood within the veins absorbs the near infrared light The generated template can be stored in either a database The sensors template library SW changes the raw image into template data The sensors wide angular near infrared camera takes a raw image of the palm vein pattern

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).
