4.13 End User A person who interacts with a biometric system to enroll or have his/her identity checked [see also User, 4.28].
4.14 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.
4.15 Extraction The process of converting a captured biometric sample into biometric data so that it can be compared to a reference template. 4.16 Friction Ridge The ridges present on the skin of the fingers and toes, the palms and soles of the feet, which makes contact with an incident surface under normal touch. On the fingers, the unique patterns formed by the friction ridges make up fingerprints.
4.17 Identification/Identify The one-to-many process of comparing a submitted biometric sample against all of the biometric reference templates on file to determine whether it matches any of the templates and, if so, the identity of the enrollee whose template was matched. The biometric system using the one-to-many approach is seeking to find an identity amongst a database rather than verify a claimed identity. Contrast with Verification (4.30).
4.18 Live Capture The process of capturing a biometric sample by an interaction between an end user and a biometric system.
4.19 Live-Scan Print A fingerprint image that is produced by scanning or imaging a live finger or palm to generate an image of the friction ridges
4.20 Match/Matching The process of comparing a biometric sample against a previously stored template and scoring the level of similarity. An accept or reject decision is then based upon whether this score exceeds the given threshold.
4.21 Minutia (single); Minutiae (pl) Friction ridge characteristics that are used to individualize a fingerprint. Minutiae occur at points where a single friction ridge deviates from an uninterrupted flow. Deviation may take the form of ending, division, or a more complicated “composite” type.
4.22 Population The set of end users for the application.
4.23 Record The template and other information about the end user (e.g., access permissions).
4.24 Resolution The number of pixels (picture elements) per unit distance in the image of the fingerprint. 4.25 Ridge Bifurcation The point at which a friction ridge splits into two ridges or, alternatively, where two separate friction ridges combine into one.
