Just as Touch ID has revolutionized authentication using fingerprints, Face ID has also revolutionized authentication using facial recognition. Face ID provides intuitive and secure authentication. made possible by the modern TrueDepth camera system. And equipped with advanced technology to accurately map the geometry of your face.
With just a glance, Face ID can safely unlock your iPhone and iPad Pro. You can use it to authorize purchases from the iTunes Store, App Store, and Book Stores, payments with Apple Pay, and more. Developers may also allow you to use Face ID to sign into their apps. Apps that support Touch ID will automatically support Face ID.
Advanced technology
The technology that enables Face ID is some of the most advanced hardware and software we have ever created. The TrueDepth camera captures accurate facial data by projecting and analyzing thousands of invisible points to create a depth map of your face and also captures an infrared image of your face. A portion of the neural engine of the A11, A12 Bionic, A12X Bionic, A13 Bionic, A14 Bionic, and A15 Bionic chips protected in the Secure Enclave converts depth maps and infrared images into mathematical representations and compares these representations with registered facial data.
To start using this technology, you must first register your face. In order to open the device using this technology, it is enough to glance at it. The TrueDepth camera has a field of view similar to when you take a photo or make a FaceTime call with the front camera. This technology works most effectively when the device is an arm’s length or less from your face (25–50 cm from your face).
Security guarantee
Security is important to all of us to protect information on devices. We’ve done a number of important things to safeguard your information, just like we’ve done with Touch ID. Face ID uses a TrueDepth camera and machine learning for a secure authentication solution. This technology data, including the mathematical representation of your face, is encrypted and protected with a key that only the Secure Enclave can access.
Privacy
Privacy is of extraordinary importance to Apple. Face ID data, including the mathematical representation of your face, is encrypted and protected by the Secure Enclave. This data will be corrected and updated as you use Face ID to improve your experience, including when you successfully authorize. it will also update the data when it detects a nearly matched face, but ultimately a passcode must be entered to unlock the device. This technology data never leaves your device, and is never backed up to iCloud or anywhere else.
In apps that support it, you can turn on Face ID to authenticate. The app will only be notified if authentication is successful. Applications cannot access Face ID data associated with registered faces. Face ID is matched with depth information, which is not found in printed or digital 2D photos.
Security
iPhone and iPad Pro and the TrueDepth camera system have been thoroughly tested and found to meet international safety standards. The TrueDepth camera system is safe to use under normal conditions of use. This system will not pose a hazard to eyes or skin due to its low output. Please note that the laser system may be disabled for safety reasons if the device is damaged or malfunctions. If you receive a notification on your iPhone or iPad Pro that Face ID has been disabled, we recommend that you have a trained technician who uses genuine Apple parts repair your device. Improper repair, modification, or use of non-genuine Apple parts in laser systems can prevent safety mechanisms from working properly and can result in hazardous exposure and injury to eyes or skin.
