mofiria has developed a Thin-Film Sensor that enables Finger Veins Authentication with Isorg

 Isorg, a pioneer in Organic PhotoDetectors (OPDs) and large area image sensors, announces the development of new device sensor prototype by mofiria based on expertise on ultra-thin vein authentication and Isorg’s technology.

In traditional vein authentication processes, optical lenses have been used to focus the light onto an image sensor, requiring a focal distance of a few centimeters to capture stable vein images. However, in this case, Isorg’s high OPD (Organic Photodetector & TFT Backplane) technology and optical control has been combined with mofiria’s unique vein authentication technology, enabling authentication in an extremely thin form factor. This allows for vein authentication to be possible in various devices and scenarios, including wearable devices, mobile devices, IoT devices, and more. It is expected that this advancement will greatly expand the range of applications and opportunities for vein authentication.

One of the features of this sensor is that the near-infrared LED that irradiates the veins can be placed on the same plane as the film sensor using mofiria’s unique reflection scattering (“method*1”), enabling more diverse product development. mofiria is already collaborating with multiple manufacturers and aims to commercialize this technology within a year at the earliest. In addition, thanks to the Isorg’s technology it is possible to adjust to various requests such as the size of the sensor depending on the shape and application of the device equipped with this sensor.

Vein authentication is a method of identifying individuals by using the unique patterns of their veins. While fingerprint sensors in film form have been used for a long time in smartphones and medical devices, fingerprint authentication carries the risk of being forged. It is also susceptible to environmental changes such as wetness, dryness, and aging of the fingers themselves.

Additionally, there are concerns regarding resistance to registration in facial recognition, the misuse of photos extracted and manipulated from social media and the internet, as well as other privacy issues. Vein authentication, which utilizes the internal information of the skin that is difficult to artificially alter, is considered the more reliable and convenient biometric authentication method, and it is gaining attention.

“In the security field, we believe there is a need for large-area sensors, ultra-thin sensors, and sensors that require sensing in the near-infrared region, which is difficult to sense with existing technologies. Our OPD technology has the power to respond to such needs, and we are pleased to be able to demonstrate our strength in the vein authentication field through collaboration with mofiria”, said Dieter May, CEO of Isorg.

“The importance of certification will only increase in the future. Combining Isorg’s cutting-edge organic film sensor with our biometric authentication algorithm enables easy, safe, and accurate personal identification in a wide range of situations. I would like to continue moving forward to realize a more comfortable and secure society,” said Akira Shibata, CEO of mofiria .

Proprietary authentication method developed by Sony, it involves illuminating the veins with near-infrared light emitted from LEDs, and efficiently capturing images of the light scattered within the body to read the veins. The distinctive feature is characterized by being able to be placed on a plane because the LED light is obliquely applied to the finger veins to capture the image.
