Glossary
Fingerprint Minutiae View (FMV)
The part of an FMD that contains fingerprint features from a single impression of a single finger.
Typically FMDs contain only one FMV.
Fingerprint template
The fingerprint minutiae data that is stored as a result of the enrollment process.
Fingerprint Devices
Fingerprint capture device
A device that collects a signal of fingerprint characteristic and outputs a fingerprint sample. This device can consist of
one or more components, including hardware and supporting software. For example, a fingerprint capture device may
include a camera, photographic paper, a printer, and/or a digital scanner.
Fingerprint reader
A fingerprint capture device that obtains a fingerprint image by direct interaction with a finger.
Fingerprint Recognition Terms
Capture
The process of acquiring a fingerprint image from a fingerprint reader or fingerprint capture device.
Enrollment
The process of capturing a fingerprint image(s) for an individual, extracting fingerprint features, optionally checking
for duplicates, and storing the fingerprint features (fingerprint template). See also FMD, Fingerprint Template.
Comparison
The function which, given two fingerprints computes a comparison score.
Comparison score
A comparison score is a numerical value resulting from the comparison of the fingerprint features of two fingerprints.
Comparison scores are of two types: similarity scores and dissimilarity scores.
Comparison scores are calculated using algorithms that are specific to the fingerprint recognition system and,
optionally, can be normalized in order to maintain a constant score distribution of impostor verification attempts or
open set identification attempts.
Similarity Score
See comparison score.
Dissimilarity Score
See comparison score.
Fingerprint Recognition
Verification or identification.
Verif ic ation
The process of
1 Capturing a fingerprint image from an individual,
2 Extracting fingerprint features,
3 Comparing the captured image’s fingerprint features with the fingerprint template(s) of the enrollee this individual
claims to be and
