![]() ![]() VeriFinger functions can be used in 1-to-1 matching (verification), as well as 1-to-many mode (identification). VeriFinger's proprietary fingerprint template matching algorithm is able to identify fingerprints even if they are rotated, translated, deformed and have only 5 - 7 similar minutiae (usually fingerprints of the same finger have 20 - 40 similar minutiae) and matches up to 40,000 flat fingerprints per second (see technical specifications for more details).Īlso, the matching algorithm has a special mode for the cases when some fingerprint records have incorrect resolution. Tolerance to fingerprint translation, rotation and deformation. ![]() Rolled fingerprints have much bigger deformation due to the specific scanning technique (rolling from nail to nail) than those scanned using the "flat" technique.Ĭonventional "flat" fingerprint identification algorithms usually perform matching between flat and rolled fingerprints less reliably due to the mentioned deformations of rolled fingerprints. The VeriFinger algorithm matches flat-to-rolled, flat-to-flat or rolled-to-rolled fingerprints with a high degree of reliability and accuracy, as it is tolerant to fingerprint deformations. The VeriFinger algorithm is based on deep neural networks and follows the commonly accepted fingerprint identification scheme, which uses a set of specific fingerprint points (minutiae) along with a number of proprietary algorithmic solutions that enhance system performance and reliability. Numerous awards in competitions and technology evaluations, including FVC and FpVTE, have been received by VeriFinger. Since that time, Neurotechnology has released more than 10 major and minor versions of the VeriFinger, providing most powerful fingerprint recognition algorithms to date. In 1998 Neurotechnology developed VeriFinger, a fingerprint identification technology designed for biometric system integrators.
