At the DEFCON virtual security conference, security researcher Yamila Levalle outlined how she was able to bypass biometric authentication for a number of different types of fingerprint scanners.

During her session [1], Levalle explained various methods of bypass including using a budget 3D printer, which yielded positive results.

Biometrics is the science of establishing or determining an identity, based on the physical or behavioral traits of an individual.
Biometric systems are essentially pattern recognition systems that read as input biometric data, then extract the feature set from such data, and finally compare it with a template stored in a database.
