When Apple revealed the face ID on the iPhone X, there were people that feared it would be the gateway to society accepting governments and other companies acquiring very personal information. It turns out, they may have been correct in their assumptions.
Apple is sharing the information of people’s facial recognition scans, and while Apple has some privacy contracts in place for app developers, they may not be enough. Whenever you allow an app to have access to the camera, the app also gains access to the TrueDepth camera. This camera creates a wireframe map of your face and can also read out 52 micro movements of your facial features. That is a lot data; the information is enough to create a 3D print of your face.
While Apple claims they protect this data by using iOS and keeping it on the iPhone X only, it is possible that people will exploit and sell this data soon. Even if you don’t mind sharing this information with apps, you should recognize the fact that this is a lot of data, worth a lot of money, that could be given to advertisers, the government, and many others. Just be aware of the significance of this data getting out: it will forever change the definition of privacy.
