The  Biometric and Identity Technology Center (BI-TC) establishes an enduring core capability by leveraging S&T’s biometric and identity expertise and capabilities to enable the re-use of biometric tools, methods, and best practices.

The BI-TC provides objective biometric and identity capabilities to DHS, enables operational components to cost-effectively use new technologies, and informs strategic planning and acquisitions of new biometric and identity capabilities. The BI-TC supports robust testing and evaluation at the Maryland Test Facility (MdTF) to inform applications of biometric technology to specific operational use cases across DHS, and the homeland security community.

For more information please view the BI-TC Factsheet.

Presentations and Videos

• Variation in the Performance of Biometric Systems: Insights Gained from Large-Scale Scenario Testing 
  • This presentation describes how data collected from these large scale scenario tests have addressed demographic effects in face recognition technologies, explains the role of image acquisition in shaping demographic differences in face recognition systems, and summarizes the implications of demographic differences in face recognition system performance for different use-cases.
• Face Recognition: Discussing Performance and Equitability
  • This video provides a high-level introduction to the components and functions of face recognition systems. It distinguishes between face recognition and image classification, which is often misunderstood and incorrectly reported, as well as provides a discussion on the performance and equitability of these systems.

• International Face Performance Conference (IFPC) – Focuses on all technical factors affecting the deployment and use of high performance face recognition applications.
  • Human Algorithm Teaming in Face Recognition (2020). S&T presentation starts at the beginning of  International Face Performance Conference (IFPC) 2020 - Day 1 Part 2 | NISTPeople are often asked to review the results of face recognition algorithms. But, we show that these results change peoples’ opinions of face similarity.  We talk about how to best combine people and algorithms on face recognition tasks.
  • Quantifying Race and Gender Effects In Face versus Iris Algorithms (2020). S&T presentation starts at 1:15:39 of  International Face Performance Conference (IFPC) 2020 - Day 1 Part 2 | NIST There is growing public concern about “bias” in commercial face recognition algorithms. We found race and gender differences in face, but not in iris algorithm performance. We discuss how to reduce demographic performance differences in face recognition.
  • Revisiting the Fitzpatrick Scale and Face Photo Based Estimates of Skin Phenotypes (2020). S&T presentation start at 1:57:54 of International Face Performance Conference (IFPC) 2020 - Day 3 Part 1 | NIST
    Computer scientists are measuring how well face recognition works for diverse people by classifying face photos using the Fitzpatrick Skin Type (FST).  We explain why using FST this way is problematic and propose better ways to measure how well face recognition works for diverse people.
