There are two variations of this technology, both of which can be found in Settings > Face ID & Passcode. Although this is more convenient, it effectively reduces the security of Face ID.
Apple’s documentation states that it “transforms the depth map and infrared image into a mathematical representation and compares that representation with the enrolled facial data.”Īs the successor to Touch ID, Apple claims that, “The probability that a random person in the population could look at your iPhone or iPad Pro and unlock it using Face ID is less than 1 in 1,000,000.” However, Apple also points out that, “The statistical probability is higher for twins and siblings that look like you, and among children under the age of 13 because their distinct facial features may not have fully developed.” Face ID’s optional trade-offs between security, convenienceĪpple “enhanced” Face ID during the COVID pandemic so it can work when you’re wearing a mask. The neural engine of the iPhone’s or iPad’s chip combines these two elements. Second, it also captures an infrared image of the face. First, the TrueDepth camera projects more than 30,000 invisible dots on the user’s face to create a depth map. Face ID doesn’t just take a photo of your face. For now, it is only available on iPhones and iPad Pro models, starting with the 2018 3rd generation iPad Pro.
Apparently it’s secure enough that financial institutions trust it for authentication, both with Apple Pay and with many banking apps. When Apple introduced Face ID, the company told us that it was secure.
This is common enough that auto-reply emails from Apple’s security team include a long section about how Face ID works and why it can be defeated in those circumstances. In an upcoming article, we’ll look at three security concerns that Apple is aware of-one of which is that twins and siblings can sometimes fool Face ID into unlocking their look-alike’s iPhone or iPad. Security & Privacy Which Is More Secure: Face ID, Touch ID, or a Passcode?
