MINEX III Compliance

These comments provided by Neurotechnology are based on NIST MINEX III results published on September 19, 2019.

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 Neurotechnology's biometric software for use with smart cards is compliant with the MINEX III requirements. In 2017 our algorithm for PC and mobile platforms submission was ranked as the top interoperable matcher and the fourth most accurate native template matcher among all MINEX III compliant matchers. In March 30, 2018 a significant breakthrough in reliability was achieved by successor MegaMatcher submission. It was 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.

Later submission from August 2018 has further demonstrated the substantial improvement of fingerprint recognition software for solutions employing biometric on-card comparison. The latest Neurotechnology's 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 second fastest in the top 10 leaderboard;
  • almost 2 times improved single finger native accuracy PIV Level 2 (comparing to the predecessor on-card comparison submission in 2016) 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 the predecessor on-card comparison submission in 2016) MINEX III compliant template generator and matcher pair;
  • circa 1.5 times improved interoperability PIV Level 1 (comparing to the predecessor on-card comparison submission in 2016) MINEX III compliant template generator and matcher pair.

Continuous development of fingerprint recognition algorithms by other vendors, as well as expansion and variation of different provider software entries within MINEX III evaluation pool diverted to progressive enhancement of the Neurotechnology's software to assure top level ranking in the leaderboard. The latest submission of the fingerprint recognition technology for use on PC and mobile platforms evaluated in July, 2019 showed another systematic improvement and regain of the leader position across extended rotatory vendor set. The submission was ranked as:

  • the most interoperable PIV Level 1 MINEX III compliant template generator, being the second fastest vendor in the top 10 leaderboard;
  • the top accuracy native PIV Level 2 MINEX III compliant template generator and matcher pair using the second fastest matcher in the top 10 leaderboard;
  • the top interoperable PIV Level 1 MINEX III compliant template generator and matcher pair with the second fastest matcher among the top 10 leaderboard.

Starting from 2015 Neurotechnology's biometric software has constantly demonstrated its compliance with the most recent PIV profile 2nd revision interoperability, native accuracy and ANSI INCITS 378 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+010A – the recent Neurotechnology fingerprint recognition algorithm, designed for use in solutions based on PC or mobile platforms;
  • Neurotechnology+0206 – the recent Neurotechnology fingerprint recognition algorithm advancement, designed for use in solutions employing card holder biometric verification on Integrated Circuit Cards (smart cards).

The tables and figures above represent performance and reliability estimates of Neurotechnology's MINEX III compliant biometric software submissions published September 19, 2019.

Neurotechnology+010A

The Neurotechnology+010A submission represents the most recent 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 July 2019. The outstanding interoperability results for Neurotechnology's latest fingerprint template generation technology, as well as the top-ranked interoperability and native accuracy results for fingerprint recognition (generator and matcher) software, easily exceed any previous MINEX III submission.

Simultaneously with the latest Neurotechnology+0206 submission detailed below, the Neurotechnology+010A generator surpass all of the 23 submitted MINEX III compliant template generators from other 18 vendors, outperforming the closest vendor submission by more than 1.2 times at PIV Level 1 interoperability for pooled, two-finger matching criteria.

The Neurotechnology+010A template generator and matcher pair has also been evaluated as the top interoperability and accuracy software submission for PIV Level 1 pooled, two-finger and PIV Level 2 native, single-finger matcher criteria respectively. Neurotechnology's submission was ranked as the top reliability fingerprint recognition solution among all 16 generator and matcher pair submissions from 11 vendors tested with 18 different vendor template generators' pool. It outperforms the equivalent PIV criteria grades competitor's submission in terms of both mean template generation and matching speed by more than 2 times each.

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. It also consolidates Neurotechnology's position as the first choice among fast and interoperable fingerprint matching software providers with prime native reliability.

Neurotechnology+0206

The Neurotechnology+0206 submission represents the recent Neurotechnology's fingerprint template generation algorithm in combination with the most recent MegaMatcher On Card fingerprint matching algorithm for performing card holder verification on smart cards. The submitted algorithm successfully passed the MINEX III validation in August 2018.

The submission has consolidated top ranked outstanding interoperability of the template generator also demonstrated by the predecessor breakthrough Neurotechnology+0108 submission, but at more than 2 times improved template creation time. Since 2018 this positions the leading template generator Neurotechnology+0206 as the second fastest vendor among the top 10 most interoperable MINEX III compliant generators leaderboard reported by NIST, while outperforming remaining vendors in top 10 leaderboard algorithms by at least 1.23 times at pooled two-finger PIV Level 1 criteria.

Compared to the predecessor on-card comparison dedicated biometric software submission in 2016, the Neurotechnology+0206 template generator exhibited in average 1.8 times better PIV Level 1 interoperability utilizing templates generated at more than 2.1 times lower timings.

The template generator and matcher pair also showed substantial improvement since MegaMatcher On Card submission in 2016 demonstrating reliability with 1.5 times improved average two-finger interoperability PIV Level 1 criteria and 1.9 times improved native single finger accuracy PIV Level 2 criteria. The recent Neurotechnology+0206 also ranked as the fastest template matching algorithm within the top 10 most interoperable MINEX III compliant matcher leaderboard while outperforming in terms of both interoperability and native accuracy many other vendor matching algorithm submissions likely dedicated to platforms with considerably higher computational capabilities than smart cards.

The Neurotechnology+0206 template generator and matcher pair verifies its compliance with the minimal two-finger interoperability and single finger native accuracy NIST SP 800-76-2 specifications demonstrating more than 8 times and more than 2 times lower actual FNMR rates respectively.
