Specification for Interoperability Testing of Contactless Fingerprint Acquisition Devices

June 8, 2022
Author(s)
John M. Libert, Shahram Orandi, Bruce Bandini, Kenneth Ko, Craig I. Watson, Christopher Stafford, Matthew E. Staymates, John Grantham
This guidance specifies a protocol and associated metrics for the evaluation of contactless fingerprint acquisition device, and their interoperability with legacy devices. This protocol enables contactless fingerprint developers seeking certification of

NIST Special Database 302: Supplemental Release of Latent Annotations

November 2, 2021
Author(s)
Gregory Fiumara, Matthew Schwarz, Jessica Heising, Jennifer Peterson, Patricia A. Flanagan, Karen Marshall
The National Institute of Standards and Technology (NIST) released a collection of latent fingerprint images as part of Special Database (SD) 302 in December 2019. While the dataset included 10 000 never-before-seen operational quality images from 200

Evaluating the Impact of Contactless Fingerprint Imagery Spatial Loss on Matcher Performance

September 23, 2021
Author(s)
Shahram Orandi, John M. Libert, Bruce Bandini, Kenneth Ko, John Grantham, Brian J. Cochran, Craig I. Watson
Observations in previous studies have shown that contactless capture devices may be prone to capturing superfluous data (e.g., fingernail or finger background), distortion and imaging artifacts especially around the periphery of the captured fingerprint

Voice Biometrics: Future Trends and ChallengesAhead

September 1, 2021
Author(s)
Doug Reynolds, Craig Greenberg
Voice has become woven into the fabric of everyday human-computer interactions via ubiquitous assistants like Siri, Alexa, Google, Bixby, Viv, etc. The use of voice will only accelerate as speech interfaces move to wearables \citestarner2002role}, vehicles

Statistics of Visual Features in the Human Iris

August 16, 2021
Author(s)
George W. Quinn, James Matey, Patrick J. Grother, Edward Watters
In most current applications of iris recognition, matching is done by computer algorithms. The dominant algorithms are based on the work of John Daugman and are well understood because of the extensive analysis in the literature of iris2pi (the shorthand

NIST Fingerprint Image Quality 2

July 13, 2021
Author(s)
Elham Tabassi, Martin Olsen, Oliver Bausinger, Christoph Busch, Andrew Figlarz, Gregory Fiumara, Olaf Henniger, Johannes Merkle, Timo Ruhland, Christopher Schiel, Michael Schwaiger
NIST Fingerprint Image Quality (NFIQ 2) is open source software that links image quality of optical and ink 500 pixel per inch fingerprints to operational recognition performance. This allows quality values to be tightly defined and then numerically

NIST 2021 Speaker Recognition Evaluation Plan

July 12, 2021
Author(s)
Omid Sadjadi, Craig Greenberg, Elliot Singer, Lisa Mason, Douglas Reynolds
The 2021 Speaker Recognition Evaluation (SRE21) is the next in an ongoing series of speaker recognition evaluations conducted by the US National Institute of Standards and Technology (NIST) since 1996. The objectives of the evaluation series are (1) to

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

June 1, 2021
Author(s)
Melissa Taylor, Brett Bishop, Ted Burkes, Michael Caligiuri, Bryan Found, Carolyne Bird, Wesley Grose, Lauren Logan, Kenneth Melson, Mara Merlino, Larry Miller, Linton Mohammed, Jonathan Morris, John Paul Osborn, Nikola Osborne, Brent Ostrum, Christopher Saunders, Scott Shappell, H. David Sheets, Sargur Srihari, Reinoud Stoel, Thomas Vastrick, Heather Waltke, Emily 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

JPEG 2000 CODEC Certification Guidance for 1000 ppi Fingerprint Friction Ridge Imagery

May 5, 2021
Author(s)
Shahram Orandi, John M. Libert, John Grantham, Michael Garris, Frederick R. Byers
The document describes the procedure by which applications of JPEG 2000 CODECs will be evaluated with respect to conformance to the NIST guidance for compression of 1000 ppi friction ridge images as detailed in NIST Special Publication 500-289 [NIST3]. The

The NIST IrisDaily Dataset: Description and Initial Analysis

May 4, 2021
Author(s)
James Matey
This paper describes a dataset, IrisDaily-NIST, that is under construction by NIST. At the present, this dataset has (nearly) daily iris images of a single subject collected with a commercial iris camera over a period of approximately 4 months. The purpose

Iris Recognition on Noah Kalina's Everyday

April 26, 2021
Author(s)
James Matey
In January 2000, Noah Kalina began taking a photograph of himself every day – and has continued for more than 20 years. A time-lapse video of his images can be seen online: EveryDay. These images, and images from similar projects, provide us with

Best practices in the collection and use of biometric and forensic datasets

March 24, 2021
Author(s)
Melissa Taylor, Austin Hicklin, George Kiebuzinski
This document discusses issues that arise in the collection, dissemination, and use of datasets for use in biometric and forensic science research, and provides recommendations on how to best address the issues raised. A variety of factors should be
