Google has started incorporating its facial scanning system since the Pixel 4, initially using its self-developed Soli radar. However, this system was only used to unlock the device and couldn’t be used for identity verification or other applications.
Recently, the facial scanning system in the Pixel 8 and Pixel 8 Pro has expanded its functionality to support identity verification in various other scenarios, including banking transactions and Google Pay. Google claims that this unlocking system meets the highest security standards on Android (Class 3).
During the launch event last night, Google didn’t mention this feature, leaving us to speculate that there may not be any significant hardware changes in the Pixel 8 in terms of the front camera. There are no additional sensors, but what has been added is the dual-pixel autofocus (DPAF) system, which improves the device’s ability to detect facial depth. This system works in conjunction with improved ML algorithms and the Tensor G3 chip, enhancing the machine learning processing capabilities.
TLDR: Google is now utilizing facial scanning technology in the Pixel 8 series, allowing for identity verification in various scenarios, including banking transactions. The new dual-pixel autofocus system and upgraded Tensor G3 chip contribute to enhanced facial depth detection and improved machine learning processing. This unlocking system meets the highest security standards on Android.
