Fujitsu Develops Biometric Mouse with
About the Technology
Fujitsu's new technology, which it has incorporated into a prototype computer mouse, identifies an individual by the unique pattern of veins in the individual's palm. Palm vein patterns are advantageous for this purpose because they are unique from one person to the next and, except for the size, they do not change as the individual ages.
Prototype vein pattern-recognition
The authentication process works as follows: The palm is first illuminated by an infra-red light. The veins just beneath the skin of the palm then emit a black reflection, giving a picture of the veins in the palm. Using a proprietary Fujitsu algorithm, a pattern is then extracted from this picture and is checked against patterns stored in the system. If there is a match, the person's identity is confirmed.
In an experiment, carried out by Fujitsu, the vein patterns of about 700 people were stored in a database system, and all were subsequently identified correctly on an individual basis. Fujitsu is confident that it can achieve an equal error rate (*3) of 0.5% or less.
Building the palm vein pattern authentication technology into a computer mouse adds security functionality without interfering with normal operations. The technology can also be built into wall-plates or mobile readers for other applications.
As work on implementing and operating these systems progresses, Fujitsu expects to offer application solutions that will:
