Welcome to the Biometrics Glossary - L - for terms beginning with L
The process of capturing a biometric sample by an interaction between an end user and a biometric system.
A fingerprint “image” left on a surface that was touched by an individual. The transferred impression is left by the surface contact with the friction ridges, usually caused by the oily residues produced by the sweat glands in the finger. See also friction ridge.
Typically refers to a fingerprint capture device that electronically captures fingerprint images using a sensor (rather than scanning ink-based fingerprint images on a card or lifting a latent fingerprint from a surface). See also sensor.
A technique used to ensure that the biometric sample submitted is from an end user. A liveness detection method can help protect the system against some types of spoofing attacks. See also challenge response, mimic, spoofing.
