The Minutiae Interoperability Exchange Test (MINEX) is nearly a decade old, born out of Homeland Security Presidential Directive-12, which calls for interoperable credentials for federal employees. The National Institute of Standards and Technology operates the test, which measures the performance of fingerprint matching software based on the standardized fingerprint templates. According to NIST, complying with the standard \u201ccreates the possibility of a fully interoperable multivendor marketplace for applications involving fast, economic, and accurate interchange of compact biometric templates.\u201d Regarding ID\u2019s Gina Jordan talks with NIST researcher Patrick Grother about the evolution of MINEX.
