Glossary and Acronyms
GLOSSARY
1:1 Mode - In 1:1 mode, a user enters his or her User ID first. Then the user is requested to
place a fin-ger or enter a PIN. In 1:1 Mode, the user’s scanned fingerprint is matched against
the one specified by the user ID.
place a fin-ger or enter a PIN. In 1:1 Mode, the user’s scanned fingerprint is matched against
the one specified by the user ID.
1:N Mode - In 1:N mode, a user places his or her finger on the device without entering an ID.
The device compares the user’s scanned fingerprint with the many enrolled fingerprints in its
internal database. Admin/Administrator - A user who is authorized to manage the settings
and user information of a fin-gerprint reader. Administrators can enroll or delete users and
change device settings.

Core - a term used to describe an area of the finger-scan characterized by ridgelines with the
tightest curvature and most unique content. Although the entire finger-scan has significant
data, the "core" is the most data-intensive area and thus is extremely important to the
algorithm. Normally, the core is located in the middle of the fingerprint.

Duress Mode - A mode that offers users a way of indicating a duress situation (such as
being forced to open a door). The user verifies with a specially designated finger resulting in
an inverted Wiegand output that is detectable on certain Access Control Panels.

Enrollment - The process of extracting features of a fingerprint image obtained from a
fingerprint sensor and saving them into the internal memory of a device. The fingerprint data
is called a fingerprint tem-plate.

Finger Placement Feedback (FPF) - FPF is a feature that allows an administrator to direct
users in cor-rect finger placement during enrollment and helps users learn correct placement.
The FPF feature helps an administrator to know when an enrolling user has positioned their
fingerprint core optimally on the scanning surface. Without this feature, the administrator has
to try to recognize the core visually and then make a judgment call as to whether the
placement was optimal. The FPF also allows the fingerprint image to remain hidden to add to
personal biometric privacy.

Firmware - The set of programs contained permanently in a hardware device (as read-only
memory) that controls the unit.

Fish - The process of threading cables or wires between points on a wall.
Host Mode - the normal mode of operation; when the unit is waiting for a card to be
presented to the device.

Identification (Searching or 1:N) - the operation of Identifying a user by comparing a live
finger scan against all stored finger-scan records in a database to determine a match.
Identification uses the finger scan only -- no cards or PINs. Identification is only available on
devices that are in 1:N mode.
