A new biometric standard, proven to protect mobile payments

trinamiX introduces a new liveness check to biometric authentication: the detection of skin. It is based on our patented technology Beam Profile Analysis, which can reliably identify different materials and thus differentiate between a life-like mask and a real face. Our solution was put to the test of accredited institutes and proved to be the world’s first to fulfill highest biometric security demands while integrated behind OLED. That’s how we create the next generation of secure face authentication for particularly sensitive smartphone applications like mobile payment.

trinamiX 3D Imaging Face Authentication: features at a glance

Growing demand for higher biometric security

trinamiX aims to solve one of today’s biggest mobile payment challenges: Its vulnerability. When it comes to the security of user authentication, mobile payment is among the most demanding yet most vulnerable smartphone use cases. Fraud attacks are already pushing security systems beyond their limits. The means to trick these systems, e.g. 3D-printed realistic replica of someone’s face, have never been more accessible – yet making spoof attacks increasingly attractive and successful.

trinamiX 3D Imaging Mobile Payment: biometric security prevents fraud attacks

Today’s biometric standards will no longer be sufficient to protect mobile payments in the future. Hence, accredited institutes and organizations for biometric security, e.g. the international FIDO® Alliance, are currently raising the bar of their requirements. Common authentication solutions need to evolve in order to meet these security standards.

Tested and certified to exceed today’s smartphone standards

trinamiX 3D Imaging Mobile Payment: spoof-proof face authentication

Today’s face authentication solutions can meet tomorrow’s biometric standards by incorporating trinamiX technology. A realistic face replica, e.g. a life-like silicone mask with accurate three-dimensional shape, might make it through the standard 3D liveness check but will not pass trinamiX skin detection. This is how trinamiX enhances the security of advanced 3D face authentication systems, thereby answering the high demands of mobile payment applications.

Our solution has been tested and certified by accredited assessment institutes according to AndroidTM Biometric Class 3 (strong), the IIFAA Biometric Face Security Test Requirement as well as FIDO Level C, the FIDO alliance’s soon-to-be highest standard. Over a period of many weeks, our technology was exposed to countless spoof attempts. It was finally accredited to be spoof-proof against these attacks, including ultra-realistic masks (Spoof Acceptance Rate according to report = 0 %). As the world’s first solution, trinamiX Face Authentication passed all these biometric security tests while the hardware was mounted behind an OLED display.

Full performance and usability

While developing a unique liveness check based on skin detection, we are determined to accomplish best performance and usability. Hence, the captured 2D image, 3D depth map and skin detection are all processed in a single, lean data stream. As a result, trinamiX Face Authentication performs in real-time (unlock duration: < 250 ms) and from darkness to bright sunlight (100 k Lux). We are thus providing a contactless, frictionless and highly reliable biometric authentication method. During mobile payment transactions, it ensures that a given user is authorized – by verifying their identity as well as their liveness.

The next generation of smartphones

trinamiX Face Authentication reliably protects users against spoof attacks, while all necessary hardware is invisibly mounted behind an OLED. It passed all biometric tests in accordance with Android Biometric Class 3 (strong), IIFAA Biometric Face Security Test Requirement and FIDO Level C, while the hardware was mounted behind the display. Our solution erases the need for a smartphone notch, which allows for sleek, full-screen display designs. Together with manufacturers, we create smartphones that combine secure biometric authentication with vast freedom of design.

Data privacy

The protection of data is our top priority. All biometric data collected during authentication is encrypted and protected by Qualcomm’s® Trusted Execution Environment. It is only stored locally on the device, without cloud computing involved.

How does it work?

The unique technology behind our face authentication solution is called Beam Profile Analysis – a method which was developed and patented by trinamiX.

trinamiX uses common face authentication hardware and transforms it into a powerful solution. The system enhances a regular 2D IR image by laser dot projection and analyzing it through our proprietary algorithms. These algorithms are able to extract the information ‘skin’ / ‘no skin’ from the dots’ specific beam profile.
