Fujitsu boosts security for multi-service palm-vein authentication system #DigInfo


Fujitsu Laboratories has developed 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. 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. 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.
