�� Matching ofMatching of::� Green Bit proprietary templates using Green Bit proprietary

matcher� ISO19794-2 / INCITS 378 templates containing Green Bit

proprietary data (originally generated by GB Coding function) using Green Bit proprietary matcher

� ISO19794-2 / INCITS 378 templates using BOZORTH matching algorithms if no Green Bit proprietary data are included

�� Conversion ofConversion of:� Green Bit proprietary templates to/from standard ISO19794-2

and INCITS 378 templates� Green Bit proprietary templates to ISO19794-2 Finger Minutiae

Card Template� ISO/IEC and INCITS to LFS Finger Minutiae Template for

International Listings – MINEX ongoing

� What is MINEX?� Continuing testing of INCITS 378 interoperability� The Minutiae Interoperability Exchange Test (MINEX) is an

ongoing evaluation of the INCITS 378 fingerprint template.

� MINEX testing provides measurements of performance and interoperability of core template encoding and matching capabilities to users, vendors and interested parties.

� DactyMatch™ is MINEX certified for encoding/feature extraction� http://www.nist.gov/itl/iad/ig/ominex_qpl.cfm (*)

(*) DactyMatch™ is coded as “2W” in MINEX listing
