MINEX III Compliance

These comments provided by Neurotechnology are based on NIST MINEX III results published on August 8, 2018.

The MINEX III evaluation is a NIST SP 800-76-2 Biometric Specifications for Personal Identity Verification (PIV) U.S. Government program compliance evaluation. It is a successor to the discontinued MINEX Ongoing program.

In 2015 Neurotechnology's MegaMatcher algorithm was the first to successfully pass the Minutiae Interoperability Exchange (MINEX) III NIST third-party evaluation, demonstrating its compliance with the state-of-the-art standards as well as its interoperability with other vendors' biometric software. Additional submissions in 2016 demonstrated that the latest Neurotechnology's biometric software for use with smart cards is compliant within the MINEX III requirements. In January 31, 2017 our submission was ranked as the top interoperable matcher and the fourth most accurate native template matcher among all MINEX III-compliant matchers. One of the latest submission, in March, 2018, demonstrated a significant breakthrough in performance. Neurotechnology's new fingerprint recognition algorithm for PC and mobile platforms has been ranked as:

  • the most interoperable PIV Level 1 MINEX III compliant template generator;
  • the most accurate native PIV Level 2 MINEX III compliant template generator and matcher pair;
  • the second most interoperable PIV Level 1 MINEX III compliant template generator and matcher pair.

The latest submission, in August, 2018, has further demonstrated the substantial improvement of fingerprint recognition software for solutions employing biometric on-card comparison. Neurotechnology's new recognition software for use with smart cards platforms has been ranked as:

  • the most interoperable PIV Level 1 MINEX III compliant template generator being the 2nd fastest in the top 10 leaderboard;
  • almost 2 times improved single finger native accuracy PIV Level 2 (comparing to predecessor on-card comparison submission) MINEX III compliant template generator and matcher each being the second fastest in the top 10 leaderboard;
  • 2.5 times improved two fingers average native accuracy (comparing to predecessor on-card comparison submission) MINEX III compliant template generator and matcher pair;
  • circa 1.5 times improved interoperability PIV Level 1 (comparing to predecessor on-card comparison submission) MINEX III compliant template generator and matcher pair.

Neurotechnology's biometric software demonstrated its compliance with the most recent PIV profile 2nd revision interoperability, native accuracy and ANSI INCITS378 standards compliance requirements. These were verified by NIST on a significantly enlarged data set (compared to the discontinued MINEX Ongoing program) by generating approximately 2 million single finger templates and performing approximately 3 million single-finger matching operations per submission. The tables below show the accuracy results for these algorithm submissions:

  • Neurotechnology+0108 – the latest Neurotechnology fingerprint recognition algorithm advancement, designed for use in solutions based on PC or mobile platforms;
  • Neurotechnology+0107 – the recent Neurotechnology fingerprint recognition algorithm, designed for use in solutions, based on PC or mobile platforms;
  • Neurotechnology+0206 – the latest Neurotechnology fingerprint recognition algorithm advancement, designed for use in solutions employing card holder biometric verification on Integrated Circuit Cards (smart cards).
  • Neurotechnology+0204 – the recent Neurotechnology fingerprint recognition algorithm, designed for use in solutions employing card holder biometric verification on Integrated Circuit Cards (smart cards).

Neurotechnology+0108

The Neurotechnology+0108 submission represents the latest advancement in Neurotechnology's fingerprint template recognition algorithms designed for use in solutions based on PC or mobile platforms. The submission successfully passed the MINEX III validation in April 2018. The outstanding interoperability results for Neurotechnology's latest fingerprint template generation technology, as well as the top-ranked native accuracy for fingerprint recognition (generator and matcher) software, easily exceeds any previous MINEX III submission.

Simultaneously with the latest Neurotechnoloy+0206 submission detailed above, the Neurotechnology+0108 template generator ranks first for interoperability among all of the 17 submitted MINEX III compliant template generators, outperforming the closest vendor submission by 1.4 times at PIV Level 1 interoperability for pooled, two-finger matcher criteria. It has demonstrated consistent interoperability, both with outside vendor products and Neurotechnology's own native predecessors (e.g., Neurotechnology+0204). In the latter instance, two-finger native fidelity improved by roughly 1.25 times.

The Neurotechnology+0108 template generator and matcher pair has also been evaluated as the most accurate software submission for PIV Level 2 mean native, single-finger matcher criteria, outperforming the closest competitor's submission accuracy by 1.35 times at a 2.67 times higher matching speed. The matcher software has been also ranked as the 2nd most interoperable submission with FNMR at FAR ≤ 1 % minor absolute deviation value being 0.001 % with respect to targeted FNMR ≤ 1 % at FMR ≤ 1 % PIV Level 1 two-finger criteria.

This MINEX III result positions Neurotechnology as the leading template-generator software provider, assuring generated data applicability in a deployed biometric system's successive evolutionary stages, both within a cross-vendor or a cross-version interoperable environment.
