Fujitsu develops slide-style palm vein authentication technology for mobile devices

Fujitsu Laboratories Ltd has developed what it calls the world’s first slide-style palm vein authentication technology, which is small enough to be built into future tablets and other handheld mobile devices, according to a report by Japan Today.

With the widespread proliferation of tablets and other compact mobile devices, there has been a growing interest in embedding an optical unit for vein authentication into these mobile devices.

However, up until now companies have struggled to manufacture an optical unit small enough to fit inside the devices.

Fujitsu said it was able to resolve this issue by developing a compact illumination component containing a single LED that lights up a rectangular target area with a uniform intensity.

The illumination device uses a new compound optical element that applies the phenomenon of diffraction.

Fujitsu also developed a new verification technology that captures the palm’s vein pattern, separating it into slices as the hand passes over the optical unit, which at only 8-mm-wide is able to be embedded into the frames of small mobile devices.

Through this method, palm vein authentication can be applied to wider application, such as accessing private, sensitive information, or using highly secure services.

Previously reported, Fujitsu will begin offering a new FIDO-compliant online biometric authentication service, which will initially roll out in Japan in early April 2017.
