Friction Ridge Image and Features (FRIF) Technology Evaluations (TEs) are a series of public tests of automated friction ridge algorithms. Algorithms tested in FRIF TEs are usually part of a larger Automated Biometric Identification System (ABIS). Tests of automated friction ridge algorithms have taken place at the National Institute of Standards and Technology (NIST) since 2004.
FRIF defines common concepts within an application programming interface (API) that apply to many different types of automated friction ridge algorithms that make up core components (but not the entirety) of an ABIS. TEs under the FRIF umbrella define an additional, more specific API for each type of friction ridge algorithm tested by NIST. These APIs allow NIST a common interface to perform testing among a width breadth of participants.
The various types of algorithms currently under test by NIST include:
Note: this TE was previously called "Fingerprint Vendor Technology Evaluation (FpVTE)."
Search one or more exemplar fingerprint image against a participant-defined database of millions of other subjects.
Note: This TE was previously called both "Evaluation of Latent Fingerprint Technologies (ELFT)" and "Evaluation of Latent Friction Ridge Technology," and has not yet been converted to the FRIF umbrella.
Search one or more friction ridge mark (colloquially, "latent") image and/or sets of friction ridge features (e.g., minutia) against a participant-defined database of millions of friction ridge exemplar and/or mark data.
Note: This TE was previously called "Proprietary Fingerprint Template (PFT)" and has not yet been converted to the FRIF umbrella.
Produce a similarity score given two exemplar fingerprint images.
Note: This TE was previously called "Minutiae Interoperability Exchange (MINEX)" and has not yet been converted to the FRIF umbrella.
Produce a similarity score given two exemplar fingerprint images, where the fingerprint feature representations (i.e., "templates") were not necessarily generated by the algorithm under test. This test supports the comparison operations performed under the US Government's FIPS 201 Evaluation Program.
Note: SlapSeg has not yet been converted to the FRIF umbrella.
Automatically draw bounding boxes around the distal phalanges present in a multi-finger impression image.
If you found a bug and can provide steps to reliably reproduce it, or if you have a feature request, please open an issue. Other questions may be addressed to the NIST FRIF team.
