For several years, Fujitsu has been developing a new type of biometric technology expected to be more secure, reliable, and perceived as less intrusive than current biometric systems, which protect against bank card thefts, fraudulent financial transactions, and unauthorized entries.

Forget about signatures and photo IDs, forget about PIN numbers, forget about fingerprint, voiceprint, iris scan, or facial recognition security technologies to counter forged or stolen user IDs. Enter Fujitsu's palm vein ID authentication, which uses an infrared sensor to capture the user's vein pattern unique to every individual's palm for an exquisitely sensitive biometric authentication technique. Fujitsu’s novel ID technology has a few other advantages over other biometric technologies. The palm vein scanner has no deleterious effect on the body, nor does it require that the device be touched, unlike current fingerprint scanners, which proved to be disadvantageous because of sanitary and/or psychological issues related to hygiene or association with criminals, as well as reasons of usability (frequent use may increase the rejection rate of the system). Other limitations of various other technologies are related to measuring external features. Aging or the camera angle could affect facial recognition systems; fingerprints can be forged, as shown by a University of Tokyo study. On the contrary, palm vein recognition seems not to be affected by aging; neither cuts, scars, tattoos, nor skin color affect the scan’s outcome; and, given that veins are internal, they can hardly be tampered with.

The Basis of Palm Vein Technology

An individual first rests his wrist, and on some devices, the middle of his fingers, on the sensor's supports such that the palm is held centimeters above the device's scanner, which flashes a near-infrared ray on the palm. Unlike the skin, through which near-infrared light passes, deoxygenated hemoglobin in the blood flowing through the veins absorbs near-infrared rays, illuminating the hemoglobin, causing it to be visible to the scanner. Arteries and capillaries, whose blood contains oxygenated hemoglobin, which does not absorb near-infrared light, are invisible to the sensor. The still image captured by the camera, which photographs in the near-infrared range, appears as a black network, reflecting the palm's vein pattern against the lighter background of the palm.

An individual's palm vein image is converted by algorithms into data points, which is then compressed, encrypted, and stored by the software and registered along with the other details in his profile as a reference for future comparison. Then, each time a person logs in attempting to gain access by a palm scan to a particular bank account or secured entryway, etc., the newly captured image is likewise processed and compared to the registered one or to the bank of stored files for verification, all in a period of seconds. Numbers and positions of veins and their crossing points are all compared and, depending on verification, the person is either granted or denied access.

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). Also, if your profile is registered with your right hand, don't log in with your left - the patterns of an individual's two hands differ. 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). No two people in the world share a palm vein pattern - even those of identical twins differ (so your evil twin won't be able to draw on your portion of the inheritance!)

Potential Applications

The new technology has many potential applications (some of which are already in use) such as an ultra secure system for ATMs and banking transactions, a PC, handheld, or server login system, an authorization system for front doors, schools, hospital wards, storage areas, and high security areas in airports, and even facilitating library lending, doing away with the age-old library card system. Fujitsu is planning to continue the development of the palm vein technology, shrinking the scanner to fit a mobile phone. Fujitsu hopes that its success might usher in a new age in personal data protection techniques, which is especially important when sales of Smartphones and other handhelds are skyrocketing.

TFOT had a quick word with Mr. H. Watanuki of Fujitsu's Biometric Business Development Department about the application of their palm vein technology.

Q: Is there currently a retail product on the market that uses your technology?
A: Yes. Some Japanese banks have adopted our palm vein authentication technology on their ATMs (e.g., Bank of Tokyo-Mitsubishi).

Q: When do you expect that commercial end-user products (such as personal computer biometric systems and door-lock mechanisms) based on your technology will be available on the global market?
A: Fujitsu has globally released an SDK (software development kit or "devkit") for palm vein technology since April, 2006. We do hope that some vendors will soon develop related products using our SDK, including the ones you have described.

Forging Palm Recognition   (02/24/09 - 22:51 - by Abhijit)
Can\'t we forge a palm recognition technique. Is there any technology
that can be used to take picture of a persons veins undernath the
palm.
Comp   (03/12/09 - 1:29 - by Afzal)
There is a chance of cuting of once palm to be used by others as an
ID?
it seems very robust...   (06/26/09 - 9:00 - by phil)
1) it is a near-infrared scan relying on the rays for capture, holding
up a picture will show up with nothing

2) since the rays are absorbed by deoxygenated hemoglobin, and thats
what creates the pattern, a dead hand would not have the correct
pattern... the vein AND arteries would show up

from a detection and access standpoint the solution seems pretty
seamless and with other manufacturers entering the field, the cost of
these readers should decrease. my only hesitation before i start
touting this as the cure for all things concerning access IdM is the
inherent problem of the root data. sure someone cannot dup a palm,
but they can still get into the database backend and insert their vein
imprint to allow access. it all gets back to securing the database
where all the information gets held. palm vein seems to have solved
the physical user side, but how is crypto doing on their end?
Not that robust...   (07/07/09 - 13:08 - by madian)
Deoxidized hemoglobin absorbs near infrared radiation, but it is not
the only substance that does so. There are plenty of markers and inks
with the same property. In many commercial scanners artificial hands
can be presented to the device and it will be fooled. In some systems
even a white sheet of paper with the vein model drawn on it is enough
(anyone can get your vein model by just photographing your hand with a
ir modified camera in plain sun or under the light of tungsten lamps)
I want to buy it   (01/26/10 - 2:33 - by Mohd Amir)
I am making a project and for that , i need this device , can please
tell me the way that how can i get it
approx. price?   (02/01/10 - 17:25 - by aaron)
Does anyone know an approx price for this product?
i want to buy one   (04/29/10 - 15:15 - by Adrian)
i am based in south africa. where do i buy this?

"In many commercial scanners artificial hands

MADIAN: Where did you get this info ?
Vascular IDM   (06/07/10 - 9:16 - by BioT)
Also MADIAN: Did you check the Near IR aborbtion RATE of deoxyhemo\'
as compared with other markers that you mention?

very useful system
To capture and store palm vein   (08/23/11 - 5:07 - by Raja Sekar J)
We had already this Fujitsu Palm vein scanner equipment. Our aim in
purchasing is to capture and store the palm vein as conventional image
files. But it is impossible to capture and store palm vein as images.
Can you help in this regard?
