VeriFinger SDK

Fingerprint identification for stand-alone or Web solutions

VeriFinger is a fingerprint identification technology designed for biometric systems developers and integrators. The technology assures system performance with fast, reliable fingerprint matching in 1-to-1 and 1-to-many modes.

Available as a software development kit that allows development of stand-alone and Web-based solutions on Microsoft Windows, Linux, Mac OS X, iOS and Android platforms.

Reliability Tests

We present the testing results to show VeriFinger 10.0 template matching algorithm reliability on the data from different fingerprint readers.

Two tests were performed during each experiment:

  • Test 1 maximized matching accuracy. VeriFinger 10.0 algorithm reliability in this test is shown as blue curves on the ROC charts.
  • Test 2 maximized matching speed. VeriFinger 10.0 algorithm reliability in this test is shown as red curves on the ROC charts.

Receiver operation characteristic (ROC) curves are usually used to demonstrate the recognition quality of an algorithm. ROC curves show the dependence of false rejection rate (FRR) on the false acceptance rate (FAR).
