The palm-vein Authentication system developed by Fujitsu laboratories is a new identification technology, which
enables palm-vein identification to be
used securely in a wider range of
situations.
Conventional palm-vein identification
works by comparing complex vein
patterns extracted from images of the
user's palm. By contrast, Fujitsu's new
technology extracts characteristic
components from the vein patterns,
and uses them to generate 2,048-bit
reference codes which are used for
comparison.
Also, when data is converted to codes,
by changing the conversion
conditions different codes can be
generated from the same image,
making it possible to use different
codes for different services.
"First, let's start signing up for
Service A. Users place their hand
here three times. My sign-up data
for Service A has been generated.
I'll try authenticating my palm
under the Service A conditions,
with reference to the data
registered for Service A. As you can
see, this is successful."

The upper figure is part of the
registered data, and the lower figure is
part of the data generated from the
palm scan. The corresponding digits
are compared, and if their match
exceeds a certain percentage,
authentication is successful. The
probability of mistaking the user's
identity is about one in 100,000.
As the data sent to the service side is
just this code, there's no need to
send the biometric data itself, which is
actually destroyed once the code is
generated. This biometric data is very
difficult to recreate from the code
alone, and even if the code is
accidentally disclosed by the service,
other services won't be affected.
"We aim to make this technology
practical by 2015. We're targeting
applications where convenience is
important, so for example, paying
for goods at convenience stores,
receiving deliveries, and accessing
Web sites."
