• Companies will demonstrate full facial authentication solution for smartphone integration and for applications behind OLED screens;
• Solution combines high-performance near-infrared global-shutter image sensor from ST and sophisticated trinamiX algorithm;
• Certified for use in mobile payments according to IIFAA, Android™, and FIDO standards.
TMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, and trinamiX, a wholly owned subsidiary of BASF SE and pioneer of new biometric technologies, today announced their collaboration on a reference design for face authentication. The solution performs behind an OLED screen and on the security level required for mobile payments. A demonstration of this system will be first presented live at IFA 2022 in Berlin on September 2-6.
The joint development and reference design for smartphone OEMs is a full system implementation that integrates illumination, a camera module that combines ST’s global-shutter image sensor with enhanced near-infrared (NIR) sensitivity (VD56G3), and trinamiX’s patent-protected algorithms running on the processor. The system offers a contactless, fast, and reliable authentication method for integration into smartphones and other products requiring user authentication. The solution’s strength lies in a unique technology, which uses skin detection to verify a user’s liveness. In addition to verifying the user’s identity, it effectively differentiates between skin and other materials, to recognize fake presentations like photos, hyper-realistic masks, and deepfakes.
“The collaboration with ST provides us with very small, high-performance image sensors at a competitive price point. This is particularly important for our products in the consumer electronics sector,” said Stefan Metz, Head of Smartphone Business Asia at trinamiX. “Furthermore, trinamiX Face Authentication can fully operate behind OLED while maintaining the highest security levels. If required, the high NIR sensitivity of ST’s image sensors supports the easy integration of our solution behind display.” According to Metz, smartphone manufacturers are thus offered a powerful, attractive package: “During the development of our smartphone reference design, we focused on particularly compact hardware sizes without compromising the performance.”
“ST’s advanced image sensors use the company’s process technologies that enable class-leading pixel size while offering both high sensitivity and low crosstalk, delivering significant improvements in performance, size, and system integration. The collaboration with trinamiX provides ST with additional opportunities to extend our support to technologies, use cases, and ecosystems addressing the thriving under-display market in Personal Electronics and beyond,“ said David Maucotel, Head of the Personal Electronics, Industrial and Mass Market Product Business Line at ST’s Imaging Sub-Group.
In 2021, trinamiX Face Authentication was approved for Android integration and certified according to the high biometric security requirements of Android Biometric Class 3, IIFAA Biometric Face Security Test Requirement, and FIDO Level C the FIDO alliance’s soon-to-be top standard.
A demonstration of the joint system for face authentication will debut at IFA 2022, taking place in Berlin, Germany on September 2-6. Customer presentations as well as appointments during the fair can be requested at info[.]trinamiX.de.
