How to Evaluate the Performance of Fingerprint Recognition Algorithms?

Fingerprint Recognition

Introduction

The fingerprint provides a perfect physiological trait to identify a person. Organisations such as schools, hospitals and government agencies use fingerprint recognition algorithms to identify, verify and authorise their staff and visitors. How do these organisations pick the best fingerprint recognition algorithms?

Organisations need to evaluate the performance of fingerprint recognition systems to pick the best solutions. So how do they evaluate the performance of fingerprint recognition algorithms? The best way to evaluate the performance of fingerprint recognition algorithms is to use the NIST proprietary fingerprint template – PFT III.

What is PFT III? How does it work? And how do organisations use pft iii to evaluate the performance of fingerprint recognition algorithms? Keep reading to discover more.

What’s PFT III?

The National Institute of Standards and Technology (NIST) uses proprietary fingerprint template technology to explore proprietary fingerprint templates’ accuracy and performance. Proprietary templates are simply a file type that stores fingerprint features in a manner that only the creators of the file can understand it.

This is different from the standardised fingerprint template that standards-compliant technologies can understand – as evaluated by the National Institute of Standards and Technology’s MINEX Program. Also, proprietary templates can be utilised in a one-to-many search as assessed in NIST’s FPVTE Program.

How to Use PFT III to Evaluate the Performance of Fingerprint Recognition Algorithm

NIST PFT III evaluation involves proprietary fingerprint templates’ performance in a one-to-one matching. The templates are tailored to every vendor’s algorithm and are, in most cases, optimised for accuracy, speed or both. Organisations can check the NIST PFT III evaluation results list to determine the best algorithm.

An algorithm that achieves a joint first place based on both speed and accuracy in the PFT III is the best. Any algorithm with a unique combination of top-ranked speed and industry-leading accuracy is the most suitable solution for implementation and use with huge databases.

It doesn’t matter whether you want to use a fingerprint recognition algorithm in your small, medium-sized or large organisation; you should always be sure to pick a system from a reliable and trusted software provider with a proven track record.
