With the increase in technology threat to personal data and national security had
also increased .The methods that were developed to secure important information from
outside intervention were not up to safe mark .There was a need to introduce a technology
that secures our data more efficiently from unlawful intervention .
Fujitsu has developed a palm vein pattern authentication technology that uses vescular
patterns as personal identification data .Vein recognition technology is secure because the
authentication data exists inside the body and is therefore very difficult to forge. It is highly
accurate. This technology can be used in various fields like banking, hospitals, government
offices, in passport issuing etc. Business growth will be achieved with these solutions by
reducing the size of the palm vein sensor and shortening the authentication time. This paper is
about the palm vein technology, its applications, how this technology is applied in real time
applications and the advantages of using this technology
In the ubiquitous network society, where individuals can easily access
their information anytime and anywhere, people are also faced with the risk that others can
easily access the same information anytime and anywhere. Because of this risk, personal
identification technology is used which includes Passwords, personal identification numbers
and identification cards. However, cards can be stolen and passwords and numbers can be
guessed or forgotten. To solve these problems, Fujitsu developed four methods: fingerprints,
faces, voice prints and palm veins. Among these, because of its high accuracy, contact less
palm vein authentication technology is being incorporated into various financial solution
products for use in public places. This paper palm vein authentication technologies and some
examples of its application to financial solutions.
3. PALM VEIN TECHNOLOGY REVIEWS:
3.1 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 nearinfrared
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.
3.2 REGISTERING THROUGH PALM VEIN TECHNOLOGY
Palm vein authentication technology consists of a small Palm vein scanner that's easy
and natural to use, fast and highly accurate. Simply hold your palm a few centimeters over
the scanner and within a second it reads your unique vein pattern. A vein picture is taken
and palm pattern registered.
WORKING OF PALM VEIN SECURITY SYSTEMS
One should place his/her palm near to scanner
2. The scanner makes use of a special characteristic of the reduced hemoglobin coursing
through the palm veins — it absorbs near-infrared light. This makes it possible to take a
snapshot of what's beneath the outer skin, something very hard to read or steal.
3. The integrated optical system in the palm vein sensor uses this phenomenon to generate an
image of the palm vein pattern and the generated image is digitized, encrypted and finally
stored as a registered template in the database
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. In addition the devices ability to perform personal authentication was verified using
1. Data from people ranging from 6 to 85 years old including people in various
occupations in accordance with the demographics realized by the Statistics Center
of the Statistics Bureau.
2. Data about foreigners living in Japan in accordance with the world demographics
released by the United Nations.
3. Data taken in various situations in daily life including gafter drinking alcohol,
taking a bath, going outside and waking up.
3.5. WHAT HAPPENS IF THE REGISTERED PALM GETS DAMAGED?
There may be a chance that the palm we had registered may get damaged then we
cannot use this technology, so during the time of registration we take the veins of both the
hands so that if one gets damaged we can access through the second hand. When hand get
damaged up to large extent we can get veins because deeper into the hand veins are obtained
When we apply this method we can maintain complete privacy.
3.6. CONTACT LESS PALM VEIN AUTHENTICATION DEVICE (HYGIENE
The complete contactless feature of this device makes it suitable for us where
high levels of hygiene are required. It also eliminates any hesitation people might have about
coming into contact with something that other people have already touched.
In addition to being contactless and thereby hygienic and user-friendly in that the user does
not need to physically touch a surface and is free of such hygiene concerns, palm vein
authentication is highly secure in that the veins are internal to the body and carry a wealth of
information, thereby being extremely difficult to forge.
In addition to the palm, vein authentication can be done using the vascular
pattern on the back of a hand or a finger. However, the palm vein pattern is the most
complex and covers the widest area, because the palm has no hair, it is easier to
photograph its vascular pattern. The palm also has no significant variations in skin
color compared with fingers or back of the hand, where the color can darken in certain
This palm vein authentication technology is used in various areas for more
security. The following are some of the important areas where it is used.
In July 2004, to ensure customer security, Suruga bank launched its ―Bio Security
Deposit‖ the world’s first financial service to use Palm Secure. This service features high
security for customers using vein authentication , does not require a bank card or pass
book and prevents withdrawals from branches other than the registered branch and ATMs
thereby minimizing the risk of fraudulent withdrawals. To open a Bio-Security Deposit
account, customers go to a bank and have their palm veins photographed at the counter in
order to guarantee secure data management, the palm vein data is stored only on the vein data
base server at the branch office where the account is opened.
In October 2004, The Bank of Tokyo launched its ―Super –IC Card‖. This card
combines the functions of a bankcard, credit card, electronic money and palm vein
authentication. This Super –IC Card contains the customer’s palm Vein data and palm
authentication algorithms and performs vein authentication by itself. This system is
advantageous because the customer’s information is not stored at the bank. When a customer applies for a Super –IC Card, the bank sends the card to the customer’s home. To activate
the palm vein authentication function, the customer brings the card and his passbook and seal
to the bank counter where the customer’s vein information is registered on the card. After
registration the customer can make transactions at that branch counter and ATM using palm
vein authentication and a matching PIN number.
In personal computers palm vein technology
can applied, by inserting the vein sensor inside
mouse. When power is supplied to system the mouse
also gets power and the sensor in the mouse will be
ready to sense palm veins. When one place his/her
palm the sensor sense the veins and if they are
matched with the registered one the system allows
the person to use it. One can use this technology even to lock folders, which can be
maintained as private information
IN HOSPITALS AND LIBRARYS:
A public library in Japan is set to become the first in the world to use palm-vein
biometrics as a substitute for conventional library cards.
The University of Tokyo hospital has taken delivery of a contactless palm vein
authentication system to secure physical access to its Department of Planning,
Information and Management
In front of our homes we can apply this Palm vein technology so that by registering
the veins of our family members and relatives we can maintain high range security which is
not possible through other technologies. Japanese recently used this technology before front
doors and getting high range security
Palm vein pattern authentication technology developed by Fujitsu was being used in a
wide range in Japan. If this technology is introduced in our country we can solve many
problems such as password protection in ATM, security in various fields and if we implement
this technology in government offices we can make the employees to work according the
government timings. Surely this technology will bring a revolution in the field of science and
technology in the near future.
