With this invention, the Touch ID is safer than the Face ID


Scientists have created a more realistic fake finger that they hope will help them improve fingerprint ID technology, used since the iPhone 5S. Fingerprint identification is almost ubiquitous now, but it remains the biggest security vulnerability of the phone .
Fake fingers already exist, but researchers at Michigan State University have created a more advanced version that can be used to test fingerprint scanners and make them harder to hack .
It is not too difficult to create fake fingers to hack a phone. CITER researchers have done this by using 3D printed molds developed from an image. At the CCC conference in 2014, a security researcher named Starbug used a high-resolution photo taken by the German defense minister to create a working model .
The author of the study Anil Jain has worked for a long time on these biometric topics. Last year, police asked their lab to re-create the fingertips of a dead man to unlock their phone , and the team succeeded on the second attempt. For this new job, the Jain team used a 3D printer to create a fake finger mold. The finger itself is made of different types of silicone and pigments.
To understand why the new finger is better, let's look at how the technology works. Fingerprint readers use different methods of identification. Some are optical scanners that basically take a picture of the fingertip and see if it matches the stored one . Some use the conductivity of the skin and electric currents to create the image instead of the light; These are called capacitive scanners and can create a clearer picture.
Another method uses ultrasound. In these, an ultrasonic pulse presses against the finger. Depending on the specific crests of the fingertips, part of the pulse is absorbed and some return to the sensor. The sensor uses mechanical stress to detect the details of the fingertips . Ultrasonic sensors see deeper than the other two, which focus on the surface level, and are more expensive and therefore rarely used.
The lab's new finger has the optical, electrical, and mechanical properties of a real finger, unlike most false fingers, which only have a couple of these properties. They can be used to test the accuracy of optical sensors versus capacitive sensors. These are the two most common types, but sometimes their readings do not match. The idea is that the new finger can help designers make their readers more accurate and responsive .
Then Jain and his team will design their own fingerprint reader to prove how good these fake fingers are. Meanwhile, the rest of us are obsessed with the face recognition technology of the new iPhone X. Who knows what the Jain team will do? Fear of knowing.
