DEFINITIONS:
AUTOMATED FACE COMPARISON - The automated search of a facial image in a
biometric database, which typically results in a group of facial images ranked by
computer-evaluated similarity.
BIOMETRICS - Distinctive and measurable human characteristics that can be used to
identify people apart from demographic data like name and date of birth. Fingerprints
and facial features are examples of commonly used biometrics. Since biometrics are
unique to individuals, they are more reliable in verifying identity than knowledge-based
methods.
ENROLL - The act of capturing a facial image, creating a template and entering the
template into a facial comparison gallery.
EXTERNAL AGENCY - Any Florida law enforcement agency with authorized access to
the PCSO facial comparison system.
FACESNXT - Is an investigative tool and any law enforcement action taken based
on a submission to FACESNXT will be based on the Department’s personnel’s
own identity determination and not solely the results of a FACESNXT search.
FACESNXT ADMINISTRATOR - The individual designated by the Department
responsible for auditing and monitoring Department user activity. The
Administrator is responsible for running reports, reviewing probe images,
reviewing OIR numbers, enabling/disabling Department users as needed,
disabling Department users who are terminated, retired or no longer need access
to FACESNXT.
FACIAL IDENTIFICATION - A task where the face comparison system searches a
database for a reference matching a submitted face image (probe) and, if found, returns
an array of possible biometrically similar identities.
FACIAL COMPARISON DATABASE - The combined files of stored templates and facial
images.
FACIAL COMPARISON SYSTEM (FCS) - The technical components of a face
comparison program, such as hardware, software, interfaces and databases.
FACIAL VERIFICATION - Manual verification is the process by which a user conducts a
one-to-one comparison between a probe and gallery face pair. Automated verification
is the process by which the facial comparison system compares a known and unknown
face pair to generate a resulting similarity score.
GALLERY - The result of an automated facial comparison search. The gallery is a rank
ordered grid of potential matching candidates to the face image (probe) submitted for
comparison.
PARTNERING AGENCY - An agency that actively contributes facial data to the Sheriff’s
Office facial comparison system or whose authorized members conduct searches within
the facial comparison application.
PROBE - The facial image or template searched against the gallery in an automated
facial comparison system.
TEMPLATE - Mathematical representation of facial features prepared from a face
image.
