Last year, for example, manufacturers began equipping smartphones with ultrasound fingerprint scanners concealed under the screen, doing away with the need for additional panels and being, at least in theory, more secure. Our colleagues at Cisco Talos decided to see how easily they could trick various types of fingerprint scanners in modern devices, or whether the technology is at last secure. First, a refresher on how fingerprint scanners work. The basic idea is simple: Place your finger on a smartphone or laptop scanner or smart lock and the sensor extracts an image of your fingerprint.
Each type of scanner recognizes fingerprints in its own way. The Cisco Talos team focused on the three most popular:. Having gotten your fingerprint, the scanner or operating system matches it against the one stored in the device. Because no existing fingerprint-reading method is perfect, each manufacturer allows a certain margin of error. The higher that margin, the easier it is to fake a fingerprint. If the settings are stricter and the margin of error is lower, the scanner is harder to trick, but the gadget is also more likely to fail to recognize its real owner.
To make a physical copy of a fingerprint, you obviously have to acquire one. The research team found three ways to do that. It is possible to take a mold of the target fingerprint when, say, the victim is unconscious or indisposed. Any soft material that sets is suitable; for example, modeling clay.
An attacker can then use the mold to make a fake fingertip. The obvious difficulty is that the attacker needs the victim to be in a suitable state and physically accessible. Another way is to get hold of a fingerprint taken with a scanner. This method is technically more complicated, but the good news for petty thieves is that not all companies that handle biometric data store it reliably.
