Last week, Apple announced its newest iPhone and some of the new technology that comes with it, including Face ID.

Current iPhones include a Touch ID fingerprint authentication system that can unlock your phone, and Face ID does the same thing — with your face.

This has some raising security concerns about consumer privacy. How easily could this technology be spoofed? Could police unlock your phone without consent just by holding it up to your face?

It turns out, Apple’s new Face ID technology isn’t entirely unprecedented. Many law enforcement agencies are already using facial recognition technology, and there have been some smaller-level versions of using it as a password of sorts.

But Apple doing this on such a large scale is unprecedented, according to Jake Laperruque. He’s senior counsel with the Constitution Project, where he works on issues like government surveillance, national security and privacy rights in the digital age.
