Proprietary Fingerprint Template (PFT) III

Proprietary Fingerprint Template (PFT) III is a fingerprint technology evaluation exploring the performance and accuracy of proprietary fingerprint templates as used in one-to-one matching. Proprietary templates are a type of file that stores the features of a fingerprint in a way that can only understood by the file's creator. This is contrast to a standardized fingerprint template, which can be understood by any standards-compliant technology, as evaluated by NIST's MINEX Program. Proprietary templates can also be used in one-to-many matching, as evaluated in NIST's FpVTE Program.


  1. The evaluation agreement can be scanned/faxed to NIST to start the PFT III test. The orginal signed document will still need mailed to us. 
  2. Wrap your algorithm in the PFT III application programming interface (API), and build it as a shared library.
  3. Follow the instructions in validation to ensure the output of your algorithm meets NIST's testing requirements.
  4. E-mail the signed and encrypted output of validation to the pft [at] (PFT team).


PFT III is the active, ongoing technology evaluation from NIST in support of one-to-one proprietary template matching. Previously, NIST conducted other one-to-one proprietary fingerprint template evaluations:
