Apple says that iOS 15 brings a fix regarding the Face ID technology, which is, of course, available to all devices with the TrueDepth sensor: all the way from the iPhone X to the iPhone 12 line and third-generation iPad Pro.
Here’s what Apple reveals that was happening:
Impact: A 3D model constructed to look like the enrolled user may be able to authenticate via Face ID
Description: This issue was addressed by improving Face ID anti-spoofing models.
The company said it “improved Face ID anti-spoofing models,” which reminds everyone of when the technology launched with the iPhone X and people tried to bypass its security by creating 3D masks. After all, we discovered that some identical twins are likely to bypass each other’s phones way more than any 3D model or 3D mask.
Although it’s an important security fix, Apple says it’s already fixed. The company also addresses a few fixes with the Neural Engine, CoreML, Siri, Kernel, Preferences, WebKit, and more.
