Fujitsu today announced the development of the world’s first slide-style palm vein authentication technology. This new technology is compact enough to be equipped to future tablets and other handheld mobile devices. As tablets and other small-scale mobile devices have become widespread, there has been interest in embedding an optical unit for vein authentication into the narrow frames of such devices, but making the optical unit smaller had been difficult. Fujitsu has succeeded in developing a compact illumination component that lights up a rectangular target area with a uniform intensity using a single LED.
Fujitsu achieved this by using a new compound optical element that applies the phenomenon of diffraction. It 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. As a result, palm vein authentication-with its superior characteristics, including highly accurate authentication and the spoof-resistance offered by biological information from within the body-can be put to wider use, such as accessing personal or other sensitive information, or using services.
