Authentication types
Devices equipped with biometric reader can be operated in 5 authentication modes. Modes 2
to 5 require an additional RFID reader.
4.5.1
Mode 1: Identification
Mode 1 is the typical biometric identification
The biometric features of all persons authorized to book are registered by an enrollment sta-
tion and distributed to the individual readers.
During a booking the fingerprint of the person is registered. The biometric features are com-
pared to the data records If a matching reference data record is found, the person has been
identified. The associated ID is sent in the registration data record to the superior access con-
trol manager.
4.5.2
Mode 2: Verification
Mode 2 is a verification based on time profiles. The person's biometric data is stored on the
RFID badge, which is used for verification.
First, a person books using the RFID badge. The ID segment and the biometric segment are
read. The master record and biometric time profile check shows whether a biometric verifica-
tion is required.
If a verification is required, the biometric reader is activated. This is the request for the person
to put on the finger. The registered biometric features are now compared to the data saved in
the biometric segment. If the features of the fingerprint are identical, the booking is valid.
4.5.3
Mode 3: Verification (ID)
Mode 3 is a verification based on time profiles of two identification features. The ID of the
RFID badge is compared to the ID of biometric identification.
First, a person books using the RFID badge. The ID segment is read.
The master record and biometric time profile check shows whether an additional biometric
identification is carried out.
If a biometric identification is required, the biometric reader is activated. This is the request
for the person to put on the finger. The biometric features are compared to the data records
of the reader's internal database. If the matching reference data record is found, the two IDs
are compared. If the IDs are identical, the booking is valid.
4.5.4
Mode 4: Combination of modes 1 and 2
Mode 4 allows parallel use of biometric identification and biometric verification based on time
profiles. A maximum of 5000 persons can be authenticated per identification. If this capacity
is insufficient, further persons can be authenticated by verification.
4.5.5
Mode 5: Combination of modes 2 and 3
Mode 5 allows parallel use of verification based on time profiles and verification (ID). This al-
lows parallel operation of RFID badges with and without biometric segment.
