Designed for doors, safes, attendance management, FA equipment and more across a wide range of industries, with ease of use in various environments and support for the New Normal through antibacterial coating
Tokyo, December 14, 2020 - Hitachi, Ltd. (TSE:6501; Hitachi ) and Hitachi Industry & Control Solutions, Ltd. ( Hitachi Industry & Control )today announced that they have developed the H4E series(1) of device-embedded-type compact finger vein authentication modules featuring vastly improved authentication accuracy and usability compared with conventional models(2) and enhance support for outdoor use. The H4E series will go on sale in Japan, the Peoples Republic of China and Europe starting today. Hitachi and Hitachi Industry & Control will take advantage of its improved outdoor performance to provide the H4E series to door lock manufacturers and home equipment manufacturers, and expand sales to a range of industries including safe manufacturers, attendance management service providers and FA equipment manufacturers.
In recent years, biometric authentication has become a familiar technology providing high levels of security and convenience for applications such as PC logins, corporate attendance management and access control system, not to mention its inclusion in smartphones. Among these technologies, finger vein authentication is unique in that the device is compact, and makes use of patterns indicating distinct biometric characteristics inside the body that make impersonation or forgery difficult and achieve high authentication accuracy. In addition, conventionally the control of biometric authentication features embedded in equipment or devices has required combined installation with high-performance control units such as PCs, but since 2008 Hitachi and Hitachi Industry & Control have been providing compact standalone module products that can perform all processes from capturing and verifying finger vein images to issuing authentication results without the need for a separate control unit.
However, with conventional embedded compact finger vein authentication modules, differences can arise between when the information is registered and authentication is performed depending on the way a finger is placed and temperature changes. When this results in authentication rejections or errors, it may be necessary to repeat the authentication process from the beginning, posing issues for operation and management. Whats more, despite the strong demand for outdoor installation of such modules, there are limits on the authentication accuracy due to dirt on the sensor and environmental resilience (applicable temperatures, dust and water-proofing). In addition to that, specifications that can stand up to alcohol sterilization to prevent the spread of COVID-19 infections are needed.
In response, Hitachi and Hitachi Industry & Control developed the H4E series, offering vastly improved authentication accuracy and usability combined with improved outdoor performance to address these issues.
The key improvements made to the H4E series are as follows.
(1) Improved authentication accuracy
Through an enlarged scanning area and improved authentication algorithms, authentication accuracy has been improved by roughly 10 times(3) compared with conventional models, offering enhanced security.
An automatic learning function for biological drift deals with differences in finger vein patterns at the time of registration and authentication due to finger placement and temperature changes, reducing authentication errors.
(2) Enhanced usability
When an authentication error occurs due to a misaligned scanning position, the continuous authentication function allows continuous authentication through minor adjustments to finger placement in real-time, shortening the time taken for re-authentication.
A three-colored LED indicator (green: operating guide, red: error, yellow: warning) and beep sound have been added as a status notification function to check that a finger has been correctly placed.
The shape of the finger guide has also been improved to naturally encourage correct finger placement.
(3) Enhanced outdoor performance and other specifications enabling embedding in various equipment and devices
With the addition of an automatic dirt detection function to the sensor, improved IP rating dust and water-proofing (4) and an expanded temperature range (-20 C to 50 C), the new specifications are suited to outdoor use. An outside light mode (5) can also be selected to facilitate authentication in environments with external light, such as outdoors.
Thanks to a more compact optical component, the module has been shrunk by around 64% compared with conventional models(6), enabling it to be embedded in a greater variety of equipment and devices than before.
(4) Support for the New Normal
To conform to the new normal, the module features an antibacterial coating(7) that allows regular sterilization with alcohol.
Going forward, Hitachi and Hitachi Industry & Control will continue to pursue the development of anti-viral coatings and new contactless authentication units that cater to customers increasingly diverse requirements and the New Normal while providing solutions that interface with various systems in the areas of IT, finance and building management to contribute to build a safe, secure and convenient society.
(1) H4E series (model: PCT-KCD0010)
(2) H2E series (model: PCT-KCC5031)
(3) Compared with conventional models, the false acceptance rate (the percentage of times a different person is incorrectly recognized as the authorized person) has been improved from 0.001% (1-in-100,000) to 0.0001% (1-in-1,000,000).
(4) The module is rated for IP54 (performance against dust ingress that would cause malfunction, protection from water spray from any direction), the equivalent of JIS Grade 4 p
