Fujitsu to Offer World's Smallest, Slimmest and Lightest Contact-Free Vein
Continuous image capture and automatic verification enable same convenient palm
vein authentication, can easily be incorporated into slim PCs and tablets
Tokyo, Apr 12, 2013 - (JCN Newswire) - Fujitsu Limited, Fujitsu Frontech
Limited and Fujitsu Laboratories Limited today announced a practical version of
the world's smallest, slimmest and lightest(1) contact-free vein
There are a multitude of vein authentication devices in the market, including
those for the finger or back of the hand, but the newly developed sensor is
unique for its compact form factor, being 5.2 mm thinner and 56% lighter than
conventional sensors. At approximately 4.0 g, the size has been reduced to a
25.0 mm width, a 25.0 mm depth, and a height of 6.0 mm. This makes it easier to
incorporate into a broader range of electronic devices, including the thinnest
of today's notebook PCs and tablets. This, in turn, helps to expand the
range of potential applications for palm vein authentication.
With the inclusion of a feature that continuously captures palm vein images,
instantly pick out the best image for authentication, and automatically verify,
users can easily perform authentication by simply placing their palm lightly
over the sensor.
Challenges to Date
To enable biometric authentication to be utilized in a wider range of
locations and circumstances, Fujitsu has sought both robust security and
superior user-friendliness for its palm vein authentication technology. At the
same time, it also aims to develop smaller, thinner sensors that can be
incorporated into a variety of electronic devices.
Fujitsu has worked to develop and commercialize thin, miniature sensors
capable of being integrated into the design of notebook PCs. However, in order
to make the technology readily applicable to an even broader range of
applications, there has been significant demand for even thinner and smaller
sensors that maintain the same high standards of security and usability.
With an eye toward incorporating this sensor into a variety of electronic
devices, Fujitsu has developed the world's smallest, slimmest and lightest
vein authentication sensor among a multitude of vein authentication devices,
including those for the finger or back of the hand. Moreover, to facilitate
integration with older versions of PalmSecure and to help users migrate to the
new technology, Fujitsu has ensured compatibility with older generations while
preserving the same usability, including continuous image capture and automatic
verification functionality. The key features of the new sensor are as follows:
1. World's smallest, slimmest and lightest sensor
To enable an even smaller and slimmer form factor, Fujitsu newly designed
lighting and optical systems as components inside the sensor used for image
capture. In fully leveraging its advantages as a palm vein authentication
sensor that is contact-free and employs an image-reflective method for
authentication, the new sensor is 25.0 mm wide, 25.0 mm deep, and 6.0 mm tall,
and weighs 4.0 g or 56% less than conventional sensors. As a result, the new
sensor is the world's smallest, thinnest and lightest of its kind, thereby
greatly increasing the range of devices into which it can be incorporated.
2. Same convenient operations through continuous image capture and automatic
The new sensor is able to continuously capture palm vein images, instantly
pick out the best image for authentication, and automatically verify. This
allows users to perform authentication by simply placing their palm lightly
over the sensor for high accuracy and convenience.
3. Can be used in combination with previous PalmSecure technology
For customers who currently use older PalmSecure technology (notebook PC
sensors, built-in keyboard sensors for desktop PCs, attachable PalmSecure-SL
sensors), Fujitsu has ensured that the new technology is compatible with older
registration/authentication data formats(2) and employs the same familiar
operation methods, such as the way users hold their hand over the sensor. This
makes it easy to use the new sensor in combination with existing sensors while
also helping users migrate to the new technology.
About Contact-Free Palm Vein Authentication
In recent years, biometric authentication, which can accurately identify
individuals based on their biological characteristics, has grown in popularity
as a means of personal identification. Of all the existing biometric
approaches, vein authentication, which reads the invisible pattern of veins in
the palm or finger, offers the benefits of being both highly accurate and
resistant to misconduct such as forgery and impersonation.
Within the field of vein authentication, Fujitsu developed the world's
first contact-free palm vein authentication technology in 2003, and began
selling palm vein authentication equipment based on this technology in 2004
(new products were introduced in 2006 under the brand name
"PalmSecure"). The technology has been highly praised for its
ease-of-use and the confidence it gives users for its robust security. It has
been widely adopted both inside and outside Japan as a means of personal
identification at financial institutions, and as a computer login and room
entrance control method at corporations.
Compared to finger veins, palm veins are more numerous and create complex
patterns, resulting in a higher volume of data. Consequently, the system's
recognition accuracy is extremely high, with a false-negatives rate of 0.01% (a
single retry) and a false-positives rate of 0.00008%(3). Furthermore, the fact
that the system uses an individual's thicker veins allows for stable
operations over time. Lastly, the system is contact-free, helping to reduce any
existing psychological burdens placed on users.
(1) World's smallest, slimmest and lightest: As of April 2013, according
to research by Fujitsu.
(2) Compatibility with older formats: Depending on the quality of data that
has already been registered with previous sensor versions, reregistration may
be necessary. In addition, due to the characteristics of the optical system
employed in the new sensor, the position (height) of the user's hand is
(3) High recognition accuracy: Authentication accuracy during one-to-one
authentication using the most advanced version of the palm vein authentication
