Biometric check, biometric data in local database
Description
In this mode, each user's card contains only an identifier. The biometric data of two
different fingers of the user are stored in the internal database, with the same user’s
identifier as the one on the user’s card.
The terminal compares the biometric data of the finger placed on the biometric sensor,
with the user’s biometric data found in the database. If a match is found, the access is
granted, otherwise (no match found) the access is denied.
User’s data required in the terminal
This authentication mode requires the creation of a record for each allowed user. Each
record contains:
•
The same user’s identifier value as the one stored on user’s card
•
The biometric data of two user’s fingers
If the user’s identifier read on the user’s card, is not found in the database, then the
access denied.
The size and the management of the MorphoAccess® terminal internal database is
described in
MorphoAccess® Terminal Database management
section.
User’s data required on card
The only data required on the user’s card is the user’s identifier. All other data is
ignored.
The terminal is able to read the user’s identifier either stored according to
TLV format
or to be read directly at a given offset on the card (
binary format
).
The TLV format is described in the
MorphoAccess® Contactless Card Specification
document.
Activation key
The configuration key below is used to activate the authentication mode with user’s
reference biometric data stored in database.
