Registration
When an administrator enrols you into the fingerprint database system, your fingerprints
will be registered. You will have to place each finger pad on the fingerprint reader sensor
four times. The best image will be saved in a database. Registered fingerprints are used
when you log into the system. For example, if your right index finger has been registered,
you can place your right finger on the fingerprint reader sensor to verify your identity
when you log on. The fingerprint on the sensor will be compared to the registered finger-
print. If your fingerprint on the sensor matches the fingerprint in the database, you are
granted access to the system.
NOTE: Once the software is installed, you will be able to register fingerprints using the
BioManager (see The BioManager chapter for details) and store them locally if you log
on as administrator on your local workstation. However, that will not grant access to
domain server accounts. To be able to log into a domain server account using your fin-
gerprint, your fingerprint will have to be registered and stored on the domain server.
Sensor
The sensor is the black window on the fingerprint reader. The sensor is used to read your
fingerprint. Do not “roll” your finger pad when you log on or register a fingerprint. Just
press it flat to the sensor.
Smart Card
A smart card is a card with information stored in a small chip. The smart card can be
described as some kind of miniature computer – it has a small processor and memory.
The difference is that the smart card is passive, i.e. it has no internal
power supply, and must hence rely on power from some kind of equip-
ment. When the smart card is inserted into the fingerprint reader, it “awak-
ens”. The fingerprint reader supplies the necessary power, and the com-
puter reads information from the chip. It is thus important to keep the chip
clean. If the chip looks dirty, you can clean it carefully with a soft cotton
cloth.
Smart Card Base Components
Smart Card Base Components provide the necessary files needed to enable applications
to communicate with a smart card through a reader attached to a PC.
Verification
When you register a fingerprint, log on or unlock a system, your fingerprint is verified.
During verification, the finger on the sensor is compared to a template of a registered fin-
gerprint from the fingerprint database. In other words, you verify that you indeed are who
you claim you are and that the fingerprint on the sensor matches the fingerprint template
in the database.
