To further standardize the Biometric recognition interface of Android phones, Google released the Android Q new generation operating system in September 2019, which added a unified facial recognition function. So, what is Android Q？

The Android Q system-level face-recognition function is realized by adding structural light，infrared and other hardware on camera scanning. According to Google's requirements, device manufacturers with versions lower than Android Q can prove that their products have facial recognition parameter performance through self-certification or third-party evaluation certification. For devices that support Android Q and above, Google has added "Android Compatibility Definition Document (CDD)" and "Measuring Biometric Unlock Security" biometric requirements, and formed Google's facial recognition algorithm test requirements and detection cases. It requires biometric recognition of functional products to be evaluated, and it is recommended to select laboratories with FIDO biometric evaluation accreditation. At the same time, Google is also considering regularly sampling inspections of products on the market in the future.

Based on long-term technical exploration and rich testing experience in the biometrics evaluation, BCTC has formed a special evaluation proposal following the relevant requirements issued by Google. BCTC has been officially recognized by Google and has become the first laboratory in the Asia-Pacific region to provide this service. During the evaluation, the 2D medium and 3D medium will be used for the presentation attack. SAR will be calculated based on the results of the attack test, and the SAR performance will be used to evaluate whether the product meets Google's requirements.
