Algorithm

A sequence of instructions that tell a biometric system how to solve a particular problem. An algorithm will have a finite number of steps and is typically used by the biometric engine (i.e. the biometric system software) to compute whether a biometric sample and template match.

Biometric data

Data encoding a feature or features used in biometric verification.

Comparison

The process of comparing a biometric sample with a previously stored reference template or templates.

Comparison score

Numerical value resulting from a comparison.

Enrollment

The process of collecting biometric samples from a person and the subsequent preparation and storage of biometric reference templates representing that person’s identity.

Extraction

The process of converting a captured biometric sample into biometric data so that it can be compared to a reference template; sometimes called “characterization”.

False match

Comparison decision of “match” for a biometric probe and a biometric reference that are from different biometric capture subjects.

False match rate

Expected probability that a captured biometric sample will be falsely declared to match to a single, randomly-selected, non-self biometric reference.

False non-match

Comparison decision of “non-match” for a biometric probe and a biometric reference that are from the same biometric capture subject and of the same biometric characteristic.

False non-match rate

Proportion of the completed biometric mated comparison trials that result in a false non-match.

matching
match
Match / Matching

The process of comparing a biometric sample against a previously stored template and scoring the level of similarity.

Process in which a biometric probe of one biometric data subject is searched against the biometric references of more than one biometric data subject to return a candidate list or a comparison decision.

One-to-one comparison

Process in which a biometric probe from one biometric data subject is compared to a biometric reference from one biometric data subject to produce a comparison score.

template
Template / Reference template

Data, which represents the biometric measurement of an enrollee, used by a biometric system for comparison against subsequently submitted biometric samples.

Note

this term is not restricted to mean only data used in any particular recognition method, such as template matching.
