This facial recognition system has undergone several iterations and is now making a comeback in terms of security.
To understand the science behind this, it’s crucial to delve into the technical aspects.
Face ID by Apple is renowned for its robust security, achieved through an infrared setup that scans the user’s face with a structured light pattern, capturing detailed depth information.

This setup creates a secure biometric profile, enabling secure mobile payments and other sensitive applications.
In contrast, most Android competitors resort to less secure facial recognition methods that use the front-facing selfie camera, which lacks the same level of security, especially for mobile payments.
The Pixel 8 Pro sets out to rewrite this narrative by integrating advanced machine learning and Google’s Tensor G3 chipset into its Face Unlock system.
The machine learning algorithms are instrumental in enhancing the recognition capabilities by continuously learning and adapting to a user’s face.
The Tensor G3 chipset is responsible for the processing power necessary to make this facial recognition technology both quick and secure.
The security of the Pixel 8 Pro’s Face Unlock technology is paramount. It is designed to be not only secure enough to unlock the phone but also to perform tasks like mobile payments and accessing banking apps.
This level of security is remarkable, as it eliminates the need to re-unlock the phone when making a purchase, a limitation found in its predecessor, the Pixel 7 series.
This enhanced security is attributed to the combination of advanced machine learning algorithms and the Tensor G3 chipset.
These technologies work together to make the facial recognition process extremely efficient.
When attempting to unlock the phone or make a payment, the Pixel 8 Pro’s Face Unlock is often faster than locating and using the fingerprint reader.

This speed and efficiency are particularly noticeable when accessing banking apps, as the system can quickly verify the user’s face, eliminating the need for additional steps like using the fingerprint sensor
The Pixel 8 Pro’s Face Unlock not only achieves higher security levels but also exhibits a perceivable speed improvement over the Pixel 7 series.
While exact measurements might be challenging to obtain, the facial recognition process is notably swift, especially in well-lit conditions.
The technology’s upgrade to Class 3 certification, the highest security level, is a substantial improvement over its predecessor, further emphasizing its efficacy.
Despite its simplicity and security, the Pixel 8 Pro’s Face Unlock technology has limitations.
It struggles to work with sunglasses on and fails in low-light or harshly backlit scenarios.
This drawback arises from the system’s reliance on the front-facing selfie camera.
It cannot match the reliability of Apple’s Face ID, which utilizes infrared technology for more accurate recognition.
The Pixel 8 Pro’s Face Unlock technology combines advanced machine learning algorithms and a powerful Tensor G3 chipset to achieve a high level of biometric security.
It is notably faster and more efficient than its predecessor, but it still faces limitations in terms of compatibility with sunglasses and challenging lighting conditions, highlighting the trade-offs made in favor of a less intrusive design compared to some competitors.
The security and speed enhancements, however, represent a significant step forward in Android facial recognition technology, aiming to compete with Apple’s Face ID.
