Security systems that can only be unlocked by fingerprints sound foolproof, but it seems there's a way around everything, and some experts are concerned that 3D printed hands with stolen fingerprints could be used to get through security at places like banks, immigration counters at airports, and police departments. The potential threat came to the attention of Michigan State University professor and biometrics expert Anil Jain, who, along with his research team, had been studying the use of 3D printed hands, complete with fingerprints, to test and calibrate fingerprint scanners. While the researchers' study was to demonstrate the efficacy of 3D printed hands for scanner testing purposes, Jain says it's now the responsibility of scanner manufacturers to prevent possible criminal use of the technology.
