Definition
Template on Card: The RB25F 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 RB25F 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 RB25F 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 RB25F 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).
The RB25F 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 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.
Bluetooth Low Energy (formerly marketed as Bluetooth Smart) is a wireless
personal area network technology.
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.
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.
The False Reject Rate (FRR) is the instance of a security system failing to verify or
identify an authorized person.
Failure To Acquire. The biometric system failure to extract usable identification data
from a biometric sample.
Typically finding a matching template in a large database of templates. 1:N matching.
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.
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.
