Osram: 3D facial recognition demonstrated during Snapdragon Summit 2022



Osram and trinamiX have demonstrated facial authentication for smartphone integration that even works behind OLED displays. Unlike Apple’s Face ID, the 3D face recognition system does not have a screen notch.

Update from November 16, 2022:

At Snapdragon Summit 2022, trinamiX presented the first full integration of its own facial authentication system. This is how technology came to you Smartphone-reference design used, while the new Qualcomm Snapdragon 8 Gen 2 was installed at the same time. Face authentication becomes instant On the back of the OLED display of smartphones, which means no extra vacation needed.

According to trinamiX, ​​the technology meets the requirements of Fido Alliance, Android Biometric Security and IIFA Mobile payments. Additionally, the whole thing should be optimized for the upcoming Snapdragon mobile platform. According to the manufacturer, Qualcomm’s Trusted Execution Environment is a new development Vitality test combined

At Sensor Converge 2022 in San Jose, USA, Group AMS Osram and BASF subsidiary TrinamiX presented a demonstration system for facial authentication. It works on the back of an OLED display and is supposed to Secure enough for mobile payments to remain expected Later this year Complete solutions for smartphone manufacturers are available. An authentication method like Face ID on the iPhone can thus be implemented without indenting or punching the display.

The compact Osram module fits behind the OLED

A special point-flood infrared projector comes from Osram, and Trinamix provides the appropriate facial authentication software. Technically it works Identification as known smartphone method, for example from Apple and Huawei. In the official videos, the Osram and trinamiX systems appear invisible. In combination with an under-display camera like the ZTE Axon 40 Ultra or Galaxy Z Fold 3 (test), so the front of the smartphone can be completely covered by the screen – Without a notch or punch hole. The hardware module measures just 8 × 16 × 4.4 millimeters.

Safe from spoofing

The complete solution is certified for several mobile payment standards, including the FIDO Alliance. Among other things, the solution checks for “liveness” and should therefore be complete Secure against spoofing attempts Even when using hyper-realistic masks. If the authentication is successful, the smartphone will be unlocked in less than 250 milliseconds. The demonstration system shown on the Trinamix product page uses a Qualcomm-Soc. Face recognition is supported by Android 10 and newer versions and is currently integrated into Qualcomm’s Trusted Execution Environment. However, it can be extended to other platforms as well.

While Apple has been emphasizing Face ID with a notch since the iPhone X, Android manufacturers continue to rely on fingerprint sensors. Apart from a few models like Xiaomi Mi 8, Huawei Mate 20 Pro (Test) and Google Pixel 4 (Test), Android smartphones have not used 3D face recognition. So far, manufacturers have always given the reason that it favors design and manufacturing costs and fingerprint sensors are now secure enough.

After the front camera and fingerprint sensors are integrated behind the display, the complete solution from Osram and trinamiX will soon enable virtually invisible 3D facial recognition on smartphones. It remains to be seen if and when manufacturers will use it in their models.
