MegaMatcher Accelerator

Solution for large-scale AFIS or multi-biometric systems

MegaMatcher Accelerator is a hardware/software solution that provides high speed, high volume biometric identification for national-scale projects.

The Extreme and Extended versions are designed to run on server hardware and perform fast biometric template matching on the server-side of a large-scale AFIS or multi-modal system. The Standard version and Development Edition are intended to be run on a common PC. MegaMatcher Accelerator software licenses are available for new and existing MegaMatcher Extended SDK customers.

Reliability Tests

We present the testing results to show MegaMatcher Accelerator 12.4 fingerprint template matching engine reliability.

These fingerprint image datasets was used for testing:

  • NIST Special Database 14 (SD14), which consists of 54,000 fingerprint images, corresponding to 27,000 unique fingers from 2,700 subjects. Information about the SD14 is no longer available, but you may check the archived copy for general information.
  • Neurotechnology's 100,000,000 artificial fingerprint images dataset. Download a small sample set.

The testing results are presented as a receiver operation characteristic (ROC) chart. ROC show the dependence of false rejection rate (FRR) on the false acceptance rate (FAR). The ROC calculation was performed by comparing all templates from the SD14 to to a gallery database, composed from a combination of both datasets.

The tests were performed with these biometric template types:

  • 1 fingerprint record – the gallery represented 100,027,000 subjects. MegaMatcher Accelerator 12.4 algorithm reliability in this test is shown as red curve on the ROC chart.
  • 2 fingerprint records – the gallery represented 50,013,500 subjects. MegaMatcher Accelerator 12.4 algorithm reliability in this test is shown as blue curve on the ROC chart.
  • 4 fingerprint records – the gallery represented 25,006,750 subjects. MegaMatcher Accelerator 12.4 algorithm reliability in this test is shown as green curve on the ROC chart.
  • 8 fingerprint records – the gallery represented 12,503,375 subjects. This test resulted in 0% false rejection rate for all false acceptance rate settings, and the reliability in this test is shown as magenta dot on the ROC chart.
