Fujitsu boasts smallest contactless vein sensor

Fujitsu vein sensor

Fujitsu Laboratories Limited claims to have developed the world's smallest, slimmest and lightest contactless vein authentication sensor.

There are a multitude of vein authentication devices in the market, including those for the finger or back of the hand, but the newly developed sensor is unique because of its compact form factor, being 5.2 mm thinner and 56 per cent lighter than conventional sensors. At approximately 4g, the size has been reduced to a 25mm width, a 25mm height, and a thickness of 6mm. This makes it easier to incorporate into a broader range of electronic devices, including the thinnest of today's notebook PCs and tablets.

With the inclusion of a feature that continuously captures palm vein images, the sensor instantly picks out the best image for authentication, and automatically verify, users can easily perform authentication by simply placing their palm lightly over the sensor.

Features

To facilitate integration with older versions of PalmSecure and to help users migrate to the new technology, Fujitsu has ensured compatibility with older generations while preserving the same usability, including continuous image capture and automatic verification functionality.

The new sensor is able to continuously capture palm vein images, instantly pick out the best image for authentication, and automatically verify. This allows users to perform authentication by simply placing their palm lightly over the sensor for high accuracy and convenience.

For customers who currently use older PalmSecure technology (notebook PC sensors, built-in keyboard sensors for desktop PCs, attachable PalmSecure-SL sensors), Fujitsu has ensured that the new technology is compatible with older registration/authentication data formats and employs the same familiar operation methods, such as the way users hold their hand over the sensor. This makes it easy to use the new sensor in combination with existing sensors while also helping users migrate to the new technology.


Contactless Palm Vein Authentication

Of all the existing biometric approaches, vein authentication, which reads the invisible pattern of veins in the palm or finger, offers the benefits of being both highly accurate and resistant to misconduct such as forgery and impersonation.

Fujitsu developed the world's first contactless palm vein authentication technology in 2003 and began selling palm vein authentication equipment based on this technology in 2004. New products were introduced in 2006 under the brand name "PalmSecure."

Compared to finger veins, palm veins are more numerous and create complex patterns, resulting in a higher volume of data. Consequently, the system's recognition accuracy is extremely high, with a false-negatives rate of 0.01 per cent (a single retry) and a false-positives rate of 0.00008 per cent. The system uses the thicker veins, which are more reliable.
