The head was printed on Backface in Birmingham, United Kingdom, where I was notified to a dome studio containing 50 cameras. Together, they combine to take a single shot that constitutes a complete 3D image.
The final model took a few days to generate at just over £ 300. With it, the author tested it against four Android smartphones and iPhone X. All Android phones tested could be unlocked with the fake 3d- printed head.
If you're an Android customer, look away from your screen now. We tested four of the hottest phones running Google's operating systems and Apple's iPhone to see how easy it would be to break into them. We did it with a 3D-printed head. All Androids opened with the fake. However, Apple's phone was impenetrable.
The tested Android phones included the LG G7 ThinQ, Samsung S9, Samsung Note 8, and OnePlus 6.
It has long been known that many face-to-face implementations across Android phones have been less secure than Apple's Face ID system. Some of these face recognition systems have been tricked with simple photographs. Apple's face ID, however, also contains IR depth mapping and attention awareness technology. Attention awareness alone may be enough to explain the inability of a static 3d-printed head to unlock iPhone X. Having said that, the iPhone Xs Face ID has been fooled in the past with more sophisticated printed 3d heads.
