Definition Edit

A biometric match is a determination that two biometric samples correspond to the same source based on some level of computer-evaluated similarity.

Overview Edit

A biometric match represents not certain recognition but a probability of correct recognition, while a nonmatch represents a probability rather than a definitive conclusion that an individual is not known to the system. That is, some fraction of results from even the best-designed biometric system will be incorrect or indeterminate: both false matches and false nonmatches will occur.[1]
