When it is required, the biometric check compares the biometric data of the finger
placed on the sensor with the reference biometric data of two fingers of the user,
acquired during enrollment process.
If a match is found, the result of the biometric check is positive: user’s identity is
confirmed. Otherwise, the result of the biometric check is negative: user’s identity is
not confirmed.
The access is granted only to authenticated users (user’s identity confirmed).
Authentication modes can be combined with a local identification in a multi-factor
mode, which is described in Section 8 Multi-factor mode section.
Data required on the user’s card
The MorphoAccess® terminal ignores contactless card encrypted with unknown
authentication keys. It means that the terminal starts the authentication process if the
user’s card is encrypted with the contactless authentication keys stored in the terminal.
The MorphoAccess® terminal rejects user’s cards without the data required by the
authentication process selected.
All authentication modes require the presence of the user’s identifier value. The other
data and the format of all the data required depends on the authentication mode
selected.
All non mandatory data found on the user’s card are ignored.
Please refer to the MorphoAccess® Contactless Card Specification document for more
information about contactless smartcard logical structure.
Authentication process options
The MorphoAccess® terminal offers several authentication processes, depending on
the user’s reference biometric data location, and the security level required.
The user’s reference biometric data can be located:
• Either on his personal card, as described in Biometric check, biometric data on
user’s card section
• Or in a record of the internal database, as described in Biometric check, biometric
data in local database
In addition, the biometric check can be disabled as specified in the section listed
below:
• Manual bypass of biometric control
• Automatic bypass of biometric control
