Identification Mode Description
Identification Process
The identification process consists in retrieving the identity of an unknown person, by
comparing the data (presented by the unknown person) with a database that contains similar
type of personal data of known persons. At the end of the process, the person is either identified
(identity found), or still unknown.
Access Control by Identification
The ‘Identification’ process on the MorphoAccess® SIGMA Family terminal begins by
comparison of the biometric data of the finger placed on the biometric sensor, with the
biometric data of all the fingers stored in the database.
It means that the biometric data of the allowed users must be stored in the internal database
before they can request the access on the terminal. This biometric data is acquired directly on
the terminal (using the Administrator interface), using the biometric sensor.
The access control by identification process is started when a finger is detected on the biometric
sensor
When the user requests the access, his identity is unknown, and it is the terminal that searches
for his identity. The terminal grants the access if a match is found (the user is identified);
otherwise the access is denied (the user remains unknown).
Result of the access control request
The result of the access right control is indicated by an audible and visible signal emitted by the
terminal. These signals are described in the “
” section.
User’s Data required in the terminal
This mode requires that all authorized users must be enrolled in the internal database of the
terminal. It means that there is one record per user: each user record contains a unique
identifier and the biometric data of two different fingers of the user.
For more information on the management of the internal database, please refer to the
“MorphoAccess® Terminal Database Management” section.
Identification Modes (database extension licenses)
Identification process relies on the database. User data is stored at the time of enrolment and
this serves as a reference for the identification process. For more details on database of
MorphoAccess® SIGMA Family terminals, please refer to “
