The mathematical map of the face is encrypted and stored securely within the Secure Enclave, a dedicated area of the device’s processor isolated from other data. The system evaluates the texture, reflectivity, and depth of the detected features to confirm liveness.
Face ID User Experience Review: How Apple's Neural Engine Delivers Secure and Intuitive Authentication
Users can glance at their device to unlock it, make secure purchases, and authenticate app logins with a natural and intuitive motion. The Role of Neural Technology Apple’s neural engine is fundamental to the intelligence behind Face ID.
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 ensures that the facial data is never accessible to apps or transmitted to cloud servers, addressing common privacy concerns associated with biometric technology.
