"I severly doubt that this method will ever be used in the real world, though it's an interesting demonstration of the technique."
Most people, it appears, are thinking in terms of theft and resale of the phone. OTOH, could a 3D scan of a face be conducted at the same time that a mug-shot is taken? Because, at that point, the police/random TLA have a photo with the requisite feature bits that correspond perfectly to the 3D map AND possession of your phone.
The future possibilities inherent in 4-color 3D printing, and the knock-on effects of that are left as an exercise for the reader.
