FVC2004

International biometric association in April 2004 held a testing of fingerprint identification algorithms “Fingerprint Verification Competition 2004”.

The competition is open and any company engaged in identification by fingerprints may participate. It is allowed to apply anonymously if the company in case of unsuccessful testing of its algorithms doesn’t want to announce its name in common list.

Applications for testing were applied by more than 120 companies from different countries and only 48 of them passed selection stage and got into the final part of the competition. Our company participated in the competition openly. The algorithms are marked under Sonda mark (registration number - PO47).

By two fingerprint databases received from optical and thermal sensors our company took first place. Given event is an outrageous result because reliability of the “Sonda” Algorithms turned out to be higher than most world leading fingerprint identification manufacturers’.

The comparison table of indicators used to compare algorithms. It’s necessary to mark that all participants were in totally equal conditions.

FMR (FAR) - False Match Rate (False Acceptable Rate).
FNMR (FRR) - False Not Match Rate (False Regection Rate).
FMR100 – False rejection rate when false acceptable rate equals 1%.
FMR1000 - False rejection rate when false acceptable rate equals 0.1%.
ZeroFMR – False rejection rate when false acceptable rate equals 0.
ERR – False rejection rate when it equals the false acceptable rate.
REJEnroll – Rejected fingerprints rate as unacceptable at the enrollment.
REJMatch – Rejected fingerprints rate as unacceptable at the matching.
AvgEnrollTime – Average time of one finger enrollment.
AvgMatchTime – Average time of one finger matching (for the “Sonda” algorithm first of all it is processing of an incoming finger and then matching with other template).
AvgModelSize – Fingerprint template average size.
MaxEnrollMem – Maximal enrollment memory required for the matching program.
MaxMatchMem – Maximal matching memory required for the program (for the “Sonda” algorithm together for processing and matching program).

Full list of participants allowed to participate in the main testing (OPEN category – is the most demonstrative. Light category has simplified procedure of evaluation):
