11.2.4 Identify performances
The identify process compare the search fingerprint to all the records of the database.
The identify process compare first the search fingerprint to the 1
st
fingerprint (fingerprint
#1) of each database record. If a match is found, the comparison process stops, else, the
identify process compare the search fingerprint to all 2nd fingerprint (fingerprint #2) of
each database record.
It means that the identification process is faster when the user place on the sensor, a
finger which is recorded as the 1st fingerprint of the user’s record. It also means that the
time required to reject a fingerprint (No Hit) is higher than the time required to match
with the 1st fingerprint of a record.

Table 6: Identify performances
Please not that:
The measure starts with finger valid placement on the sensor and stops with result
returned to the host system.
the time value is intended for typical fingerprints : more characteristic points per
fingerprint (such as for a thumb fingerprint) means more time.
Add 1 second to ‘no hit’ time when ‘advanced matching’ is used (please refer to the
definition of ID_Matching_Strategy optional ILV in ‘MorphoSmart™ Host System
Interface specifications’ document)
The time value can be multiplied by 2 when ‘not oriented matching’ is used (please
refer to the definition of value 2 for Sensor_Window_Position ILV definition in
‘MorphoSmart™ Host System Interface specifications’ document).
