Jain’s research focuses on producing biometric identifiers, such as fingerprint scanners and facial recognition software, secure and complex to trick. Helping law enforcement with their investigation is therefore doing the precise opposite. Whilst hacking biometric security with measures such as a 3D printed replica finger may pose a security risk if the tools fell into the wrong hands, that successfully doing so can inform Jain’s research.
“We do it for the fun,” said Jain.
A plastic replica of a finger isn’t adequate to trick a fingerprint scanner, that requires a conductive surface, such as skin, to close small electrical circuits. To overcome this problem, Jain and his PhD student Sunpreet Arora covered the 3D printed fingertips with a thin layer of metallic particles.
