World’s first palm vein authentication technology has been developed by Fujitsu and it is so small, that it can be used on future tablets and handheld mobile devices thereby broadening the authentication technology options that customers can chose from.
Fujitsu says that it has succeeded in developing a compact illumination component that lights up a rectangular target area with a uniform intensity using a single LED. This was achieved by using a new compound optical element that applies the phenomenon of diffraction.
Fujitsu has also developed a new verification technology that captures the complete pattern of a palm’s veins, dividing the pattern into slices as the hand passes over the optical unit, which at a mere 8 mm wide is able to be embedded into the frames of compact mobile devices.
The Japanese company points out that password based authentication technologies are increasingly becoming unreliable and this is fuelling increased use of biometric authentication. Fujitsu says that palm vein authentication technology uses biological information that is difficult to spoof and given that it has been able to develop the technology for use in mobile devices, more and more businesses and consumers can protect their information with ease.
Palm vein authentication technology utilizes images captured by illuminating a palm with the safe near-infrared band light, which passes easily through the body, and reads vein patterns from the captured image. Accordingly, a palm vein authentication device’s optical unit consists chiefly of an illumination component and an image capture component. In order to uniformly illuminate the entire palm, the illumination component, the widest part of the optical unit, is arranged to surround the image capture component. The issue, however, has been in making the component smaller. Moreover, if the image capture component is made smaller, the area that can be read on the palm veins becomes narrower, making authentication more difficult because the read area in palm veins is significantly different with every capture image when registering or verifying. As a result, it has been difficult to create technology that both enables the optical unit to be smaller and achieves accurate authentication.
About the Technology
In this world’s first slide-style palm vein authentication technology, Fujitsu has miniaturized the optical unit to a mere 8 mm in width, allowing it to fit within the touch panel of mobile devices. This enables authentication simply by sliding one’s fingers across the touch panel.
Fujitsu Laboratories has reduced the width of the optical unit for palm vein authentication to a mere 8 mm, achieving a size small enough to fit in the frame of tablets or other compact mobile devices that have narrow borders. Furthermore, combining a slide action with an authentication algorithm means verification just as dependable as current optical units.
