A technology attracting attention as the most reliable way to authorize ID
What are the main techniques used to authorize someone's ID when they use an ATM or access an office? Generally the answer is ID numbers or ID cards. But simple ID numbers risk discovery by other people, while ID cards can easily be lost or stolen. This paved the way for a new technology that is attracting attention by authenticating people's ID using part of their body.
This technology is called "biometric authentication," and today, technologies using biometric information such as veins and fingerprints, as well as the eye's retina or iris, are being commercialized. Biometric authentication enables high-accuracy recognition of the biometric information unique to individuals, and it is considered one of the most reliable means of confirming a person's ID.
Providing the highest level of accuracy compared with many other biometric authentication technologies
Fujitsu's proprietary technology "Palm Vein Authentication" achieves the highest level of accuracy against many other competing biometric authentication technologies. Simply holding the palm of your hand over the dedicated sensor allows vein patterns to be read and compared to the ones registered in advance to confirm your ID. Its authentication accuracy level is so high that the probability of mistaken ID is one in 1.25 million people or fewer (Note).
(Note) Based on the values for the PalmSecure sensor V2, the false acceptance rate is 0.00008% or less when the false rejection rate is 0.01% (including one retrial).
Previous dedicated vein sensors have had the drawbacks of being large, and slow in authentication. Fujitsu has succeeded, however, in reducing the size of its sensor to about one fortieth of the previous, from about 7.0 cm (width) x 7.0 cm (depth) x 3.0 cm (height) in 2004, when it was first launched, to about 2.5 cm (W) x 2.5 cm (D) x 0.6 cm (H) today. Authentication speed has increased from about 3.0 seconds to about 0.6 seconds. This has allowed Fujitsu to provide mice, laptops, and tablets with built-in sensors.
Developing ID verification technology that is easy to use for both young and old
Currently, Fujitsu's palm vein authentication technology is already being used by many customers across the world, including those who handle confidential information. The technology is used in areas like ATMs, entry and exit at security areas and factories, and log-in to computers at businesses. Recently, the Soka city government in Saitama, Japan, started to use this technology to log into almost all the computers used in its offices.
In addition, thanks to its fast authentication, high accuracy, and contact-free use, Naka City Library in Ibaraki, Japan, has developed a cardless book-lending service using Palm Vein Authentication. In the future, a wide range of applications that do not require cards may become a reality. One example is a system that allows passengers to take trains by simply holding their hand over the sensor instead of showing an IC card. Another application could enable shoppers to make purchases by simply using the sensor rather than a credit card.
In the years to come, Fujitsu aims to further improve this technology and develop it so that people, young and old, can use it easily in daily life to enhance their sense of security and convenience.
