Additionally, the system requires a deliberate glance to register intent, preventing accidental triggers when the device is merely glanced at from a distance. The captured data is processed by the device’s neural engine, a dedicated chip designed specifically for machine learning tasks, to verify a match against the stored mathematical representation.
This means that the authentication process requires the user’s actual presence, effectively blocking attempts to trick the system with two-dimensional images. Security and Privacy Considerations Security is paramount in biometric authentication, and Face ID is engineered with multiple layers of protection.
