Fujitsu Laboratories Ltd has developed a technology that can compare biometric information while it is still encrypted, with the same accuracy and processing speed as conventional biometric authentication systems.

Conventional technologies have been developed that can authenticate encrypted biometric information, but there were issues with the comparison accuracy or in the processing speed. Now, Fujitsu Laboratories has developed a technology that uses palm vein authentication to prevent the degradation of comparison accuracy that occurs when encryption is applied, while increasing the speed of comparison processing.

Because this technology enables quick and accurate comparison of biometric information while it is constantly encrypted, it can create a payment system using safe and secure palm vein biometric authentication in environments such as a cloud environment via the internet.

Development background

In recent years, the use of biometric authentication has become more common as a safe and convenient method of identifying a person. Fujitsu Laboratories early on developed palm vein authentication to meet the need for an authentication system that could identify a person with just biometric information, without using information such as a password or a card. In 2018, Fujitsu Laboratories announced a biometric authentication technology that combined facial recognition with palm vein authentication.

Fujitsu said in a statement that it expects to see wider use of biometric authentication in a variety of situations, such as for payments when shopping, for logging in to websites and systems, and for accessing secure rooms.Conventional biometric authentication systems could only operate in closed environments using dedicated connections.

In the future, however, the implementation of biometric authentication systems operating in open environments via the internet is expected, as there will be more usage of cashless payment at large-scale chain stores
