Fake Fingerprints - Liveness Detection Solutions

Author: Brian Rhodes, Published on Oct 19, 2015

One of the biggest concerns with fingerprint readers is how easy they can be fooled. While biometrics are typically more difficult to steal or fake, headlines still break news of fake fingers or stolen prints being used to fool sensors.

For this reason, many access control fingerprint readers include live finger or liveness detection that checks the finger being scanned is authentic.

In this note, we examine the four common methods (tissue reflection, heartbeat detection, dermal electric resistance, unnaturalness analysis), what HID, Morpho and Suprema use and why you need to beware of ambiguous claims.
