Setting up matching threshold
The performances of a biometric system are characterized by two
quantities, the False Non Match Rate - FNMR - (Also called Fale
Reject Rate) and the False Match Rate - FMR - (Also called False
Acceptance Rate). Different trade-off are possible between FNMR
and FMR depending on the security level targeted by the access
control system. When convenience is the most important factor the
FNMR must be low and conversly if security is more important
then the FMR has to be minimized.
Different tunning are proposed in the MorphoAccess terminal
depending on the security level targeted by the system. The table
below details the different possibilities.
From the System Menu, press the CONFIG key to access the
configuration files. Press the NEXT key until the file menu shows
"/cfg/ bio".
