Fake Finger to Help Designers Make Fingerprint Readers More Sensitive and Accurate

Published By : 22 Sep 2017 | Published By : QYRESEARCH

In the hope to improve fingerprint ID technology, scientists have developed an extremely realistic fake finger. While fake fingers already exist, scientists from Michigan State University have created a more advanced version, one that can be used to test fingerprint scanners, with the motto of making them harder to hack. Fingerprint ID is almost everywhere now. However, they remain a threat to security. It is not too difficult to create fake fingers for hacking onto a phone.  Researchers at CITER have done these using 3D-printed molds, which were developed from an image. To everyone’s shock a security researcher called Starbug made use of a high resolution photo of the hand of the defense minister of Germany to create a working model, at the CCC conference in 2014

New Fake Finger has Electrical, Mechanical, and Optical Properties of a Real Finger

Anil Jain, who is the author of the study has worked on these biometric issues. In 2016, police asked Jain’s lab to re-create the fingertips of a deceased man so as to unlock his phone. The team succeeded merely on their second attempt! The lab’s new fake finger has the electrical, mechanical, and optical properties of a real finger, which is not something most fake fingers possess. This makes these fake fingers superior than most. The idea is to make this fake finger help designers in making their fingerprint readers more sensitive and accurate. Jain and his team are planning to design their own fingerprint reader so as to test how good these fake fingers are.
