How Face ID Works

Face ID employs a sophisticated system that captures and analyzes a 3D map of a user’s face, creating a unique digital representation. This process involves multiple steps:

• Infrared Camera: A specialized infrared camera projects an array of invisible infrared dots onto the user’s face, creating a depth map of facial features. This depth map is used to create a 3D model of the face.
• Flood Illuminator: This component emits infrared light to illuminate the face, ensuring accurate image capture even in low-light conditions.
• Dot Projector: This component projects thousands of invisible infrared dots onto the user’s face, creating a depth map of facial features.
• Facial Recognition Algorithm: The captured data is then processed by a powerful neural network, which compares the 3D model to the stored facial data. This algorithm analyzes the unique patterns and characteristics of the face, such as the distance between the eyes, the shape of the nose, and the contours of the cheekbones.
• Authentication: If the algorithm identifies a match, the device unlocks, granting access to the user’s data. If no match is found, the device remains locked.

Security Measures, Two oled iphones face id 2018

Face ID incorporates numerous security measures to prevent unauthorized access:

• Secure Enclave: The facial data is stored securely in a dedicated hardware component called the Secure Enclave, isolated from the main operating system and protected by advanced encryption. This ensures that the data is inaccessible to malicious software or unauthorized parties.
• Attention Detection: Face ID requires the user to look directly at the device during authentication, ensuring that the device is not being unlocked by a photo or a mask. This feature adds an extra layer of security by verifying that the user is actually present and attentive.
• Dynamic Depth Mapping: The system constantly updates the facial map, adapting to changes in appearance like wearing glasses or growing a beard. This ensures that Face ID remains accurate and reliable over time.
• Anti-Spoofing: Face ID is designed to resist spoofing attempts using photos, masks, or other impersonation methods.
