Contactless Fingerprint Capture and Data Interchange Best Practice Recommendation

March 11, 2021
Author(s)
Shahram Orandi, John M. Libert, Craig I. Watson, Gregory Fiumara, John Grantham
While contactless fingerprint capture devices stand to provide for many benefits, images from this nascent technology are sufficiently different than traditional contact-collected images thereby warranting the separation of these new contactless

White-Box Evaluation of Fingerprint Matchers: Robustness to Minutiae Perturbations

January 6, 2021
Author(s)
Steven Grosz, Joshua J. Engelsma, Nicholas G. Paulter Jr., Anil K. Jain
Prevailing evaluations of fingerprint recognition systems have been performed as end-to-end black-box tests of fingerprint identification or authentication accuracy. However, performance of the end-to-end system is subject to errors arising in any of its

Evaluating the Operational Impact of Contactless Fingerprint Imagery on Matcher Performance

September 15, 2020
Author(s)
Shahram Orandi, John M. Libert, Bruce Bandini, Kenneth Ko, John D. Grantham, Craig I. Watson
This study set out to examine the operational impact of introducing contactless fingerprint imagery to a modern fingerprint matching system that was designed for touch-collected images in either a standard Ten-Print operational matching pathway or a Mobile

Analysis of Iris Images in Nicholas Nixon: The Brown Sisters

June 17, 2020
Author(s)
James R. Matey, Patrick J. Grother, George W. Quinn
In this paper we present results that expand on the Afghan Girl study by Daugman using gray-scale photographs of 4 subjects taken every year for 40 years: The Brown Sisters photographic project by Nicholas Nixon. We extracted iris images from the

Analysis of Iris Images from Twins Day – 2010

June 16, 2020
Author(s)
James R. Matey, Patrick J. Grother, George W. Quinn
Each year since 1976, the town of Twinsburg, Ohio has held a Twins Day Festival. Over the past 43 years over $77,000$ sets of twins and multiples have attended -- with many repeat visits over the years. Prof. Jeremy Dawson and other staff from the the West

Interoperability Assessment 2019: Contactless-to-Contact Fingerprint Capture

May 19, 2020
Author(s)
John M. Libert, John D. Grantham, Bruce Bandini, Kenneth Ko, Shahram Orandi, Craig I. Watson
This report describes computational comparison measurements as well as match error analysis applied to fingerprint images collected by researchers of the National Institute of Standards and Technology (NIST) in May of 2019. Fingerprint images from 200

Forensic Handwriting Examination and Human Factors: Improving the Practice Through a Systems Approach

Vastrick, Heather E. Waltke, Emily J. Will
For some 6,000 years, humans have made an indelible mark on history through the loops, strokes, and other characters that constitute the written form of language - handwriting. The study of handwriting is also an important part of forensic science. By

NIST Special Database 302: Nail to Nail Fingerprint Challenge

December 11, 2019
Author(s)
Gregory P. Fiumara, Patricia A. Flanagan, John D. Grantham, Kenneth Ko, Karen Marshall, Matthew Schwarz, Elham Tabassi, Bryan Woodgate, Christopher Boehnen
In September 2017, the Intelligence Advanced Research Projects Activity (IARPA) held a data collection as part of its Nail to Nail (N2N) Fingerprint Challenge. Participating Challengers deployed devices designed to collect an image of the full nail to nail
