Using a false fingerprint to fool a fingerprint scanner might sound like something out of a spy movie, but researchers at Michigan State University recently did just that. The researchers printed an entire 3D hand that could be used to fool a commercial scanner. But professor Anil Jain’s hope is that instead of fooling scanners, these printed hands would be used to calibrate, or standardize, commercial scanners. A consistent “hand” to test scanners with would make scanners less susceptible to fake fingerprints from criminals. Having successfully printed a hand of his own, Jain hopes companies will now take this information and use it to improve their products.
