APPENDIX A: GLOSSAR Y 263

QC—Quality control. Editing of fingerprint minutiae to improve accuracy for
identification. The quality of tenprint images is automatically determined,
and poor quality images are sent to QC for editing.
RADIOMETRIC RESOLUTION—Number of intensity levels, e.g., shades of
gray or color values in a digital image.
RELAUNCH—Searching a latent print case after the initial LT/TPlc search
using different search parameters while maintaining the same case identifiers
and images.
RELIABILITY—The probability that the mating fingerprint will be hit if the
mate is in the file being searched.
REMOTE TENPRINT FINGERPRINT FEATURE SEARCH (NATIVE MODE)—
A search request transmitted to the FBI originating outside the identifica-
tion, tasking, and networking (ITN) workstations. The fingerprint features
submitted for the search were derived by an AFIS in a similar manner to those
derived by AFIS/FBI. The transmission includes fingerprint features along
with the necessary fingerprint classifications and other data. The search
request is performed automatically by AFIS/FBI without human involvement.
RFES—Remote fingerprint editing software. Software package from the FBI
used to perform remote searches on IAFIS. Supports remote IAFIS transac-
tions, including image- and features-based searches for latent and tenprint
applications.
ROLLED IMPRESSION—Fingerprint impressions created by individually
rolling each finger from side to side (nail to nail) to obtain all available fric-
tion ridge detail. The images appear in the individual print boxes on the ten-
print card.
SCANNER—Capture device to create digital image. Must meet at least Appen-
dix G standards for AFIS applications that connect to the FBI.
SEARCH SELECTIVITY—The total number of incorrect candidates divided by
the total number of searches conducted during the time period. That is, the
number of incorrect candidates, averaged over time periods, produced for
comparison per search at the operating point at which search reliability is
measured.
SEARCH, THE NATIONAL CONSORTIUM FOR JUSTICE INFORMATION
AND STATISTICS—A nonprofit membership organization dedicated to
better criminal justice information management, effective identification tech-
nology, and responsible law and policy.
SEGMENT—One of the constituent parts into which an automated system may
be logically divided. IAFIS consists of the segments of ITN, AFIS, and III.
SERVICE PROVIDER—A member of the FBI staff who supports or provides
FBI identification services to the criminal justice community (federal, state,
and local users) and other authorized users. Service providers perform activ-
