Contactless Fingerprint Capture and Data Interchange Best Practice Recommendation Revision 1

August 5, 2024
Author(s)
Shahram Orandi, Craig I. Watson, Jennifer Stathakis, John M. Libert, 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

Repeatability of Contactless and Contact Fingerprint Capture

September 12, 2023
Author(s)
John M. Libert, Shahram Orandi, John Grantham, Kenneth Ko, Bruce Bandini
A new generation of contactless fingerprint capture devices has recently emerged. These devices provide the ability to capture a fingerprint without making physical contact with the finger. There is anecdotal evidence that the process of capturing a

Guidance on Contactless Friction Ridge Image Compression, v1.0

May 3, 2023
Author(s)
John M. Libert, Shahram Orandi, Kenneth Ko, Bruce Bandini, John Grantham, Craig I. Watson
Nascent technologies show promise in collecting 500 ppi fingerprints in a contactless fashion while yielding various improvements in the collection process over legacy contact collection methods currently in use throughout the world. While it has been

Specification for Certification Testing of Contactless Fingerprint Acquisition Devices, v1.0

April 4, 2023
Author(s)
Shahram Orandi, John M. Libert, John Grantham, Kenneth Ko, Bruce Bandini, Craig I. Watson
This specification builds upon the protocols and metrics established in NIST Special Publication 500-336 and defines procedures for the evaluation and certification of contactless fingerprint acquisition devices with respect to certified legacy contact

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

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

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

Contactless Fingerprint Capture and Data Interchange Best Practice Recommendation

March 11, 2021

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

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

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

Compression Guidance for 1000 ppi Palm and Hand Friction Ridge Imagery

July 2, 2019
Author(s)
John M. Libert, John D. Grantham, Craig I. Watson
NIST provided in a special publication guidance for the compression of 1000 ppi fingerprint images using Part I of the JPEG 2000 standard. The present document extends the Guidance to the compression of 1000 ppi palm and whole-hand images. The NIST
