Identification mode description
Identification process
The identification process consists in retrieving the identity of an unknown person, by
comparison of a personal data with a base which contains the same 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 of the MorphoAccess® terminal proceed 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. The biometric data of
allowed users are acquired by an enrolment station, with the same kind of 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 MorphoAccess® terminal itself. These signals are described on the
Access control result
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 authorized user: each user record
contains a unique identifier and the biometric data of two different fingers of the user.
The management of the internal database is described in the
MorphoAccess® Database
management
section.
