The head was printed at Backface in Birmingham, U.K., where I was ushered into a dome-like studio containing 50 cameras. Together, they combine to take a single shot that makes up a full 3D image. That image is then loaded up in editing software, where any errors can be ironed out. I, for instance, had a missing piece of nose.
Backface then constructs the model with a 3D printer that builds up layers of a British gypsum powder. Some final touch-ups and colourings are added, and the life size head is ready within a few days, all for just over £300. You’re then the proud owner of an uncanny, almost-spectral version of your own visage.
For our tests, we used my own real-life head to register for facial recognition across five phones. An iPhone X and four Android devices: an LG G7 ThinQ, a Samsung S9, a Samsung Note 8 and a OnePlus 6. I then held up my fake head to the devices to see if the device would unlock. For all four Android phones, the spoof face was able to open the phone, though with differing degrees of ease. The iPhone X was the only one to never be fooled.
Emphasis mine. Very much looking forward to Face ID on my next Apple phone.
