Authentication Mode
(Signo 25B)
Template on Card: The Signo 25B is waiting for a Credential (Card) to be presented. It retrieves
all the biometric templates from the credential.
If the presented finger matches the biometric templates retrieved from the credential a Grant
Access is recommended. This is a 1:1 Verification match against Template on Card (TOC). The
sensor is not armed (blue light off) until the Credential is presented.
Card + Finger: The Signo 25B is waiting for a Credential (Card) to be presented. It looks up the
user ID and all associated biometric templates in it’s local device database. If the presented
finger matches the biometric templates retreated from the local database a Grant Access is
recommended. This is a 1:1 Verification match against Template on Device (ToD). The sensor is
not armed (blue light off) until the Credential is presented.
Finger Only: The Signo 25B is waiting for a finger to be presented that is stored in its local device
database. If the presented finger matches one stored in the database a Grant Access is
recommended. This is a 1:N Identification match against Template on Device (ToD). The sensor
is always armed (blue light on).
Card Only: The Signo 25B is waiting for a Credential (Card) to be presented. It reads the PACS
data only and always recommends a Grant Access. The sensor is never armed (blue light off).
Card Only (or) Finger Only: The Signo 25B is waiting for either a Credential (Card) to be
presented or a finger, stored in its local device database, to be presented. This authentication
mode is particularly useful during initial enrollment setup.
Biometric spoofing
Biometric spoofing is a method of fooling a biometric identification management system. An
artificial object (for example, a fingerprint mold made of silicon) is presented to the biometric
scanner that imitates the unique biological properties of a person which the system is designed
to measure.
BLE
Bluetooth Low Energy (formerly marketed as Bluetooth Smart) is a wireless personal area
network technology.
ERR
The Equal Error Rate (EER) is the common value indicating that the proportion of false
acceptances (FAR) is equal to the proportion of false rejections (FRR). The lower the EER value,
the higher the accuracy of the biometric system.
False Accept Rate (FAR)
The False Accept Rate (FAR) is the measure of the likelihood that the biometric security system
will incorrectly accept an access attempt by an unauthorized user.
False Reject Rate (FRR)
The False Reject Rate (FRR) is the instance of a security system failing to verify or identify an
authorized person.
FTA
Failure To Acquire. The biometric system failure to extract usable identification data from a
biometric sample.
Identification (of Identity)
Typically finding a matching template in a large database of templates. 1:N matching.
LFD
Live Finger Detection. This is used in some markets instead of Spoof. It is also used to refer to
insuring a severed finger is not being presented at the sensor.
MINEX
Minutia Interoperability Exchange. The MINEX program is dedicated to the evaluation and
development of the capabilities of fingerprint minutia matchers running on ISO/IEC 7816 smart
cards.
M-Series
Mercury Platform Series of Products.
