Available in PDF, EPUB and Kindle. Book excerpt: The use of biometrics to identify individuals has become an important component of efforts to ensure U.S. national security, and has also grown rapidly. Biometrics are, for example, an integral part of the United States Visitor and Immigrant Status Indicator Technology (US-VISIT) program. To address contagion and speed issues, DHS S&T commissioned and funded a project to research technologies that could be used to acquire fingerprints without physical contact. Overall the contactless scanner took longer to acquire the prints, acquired fewer prints under the no instruction and video instructional conditions, and was preferred less than the contact scanner.

Download or read book Usability Testing of Height and Angles of Ten print Fingerprint Capture written by Mary Theofanos and published by Createspace Independent Publishing Platform. This book was released on 2008-06-30 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Homeland Security (DHS) and the United States Visitor and Immigrant Status Indicator Technology (US-VISIT) program is preparing to transition from a two print capture process to a 10-print slap capture process. In preparing for the 10-print pilot testing, a concern that the existing counters that house the fingerprint scanners are too tall to support the ten print collection process was identified. Lowering the counters in the facilities is not possible for the pilot testing. However, angling the scanners on the counter may alleviate the problems. US-VISIT asked the National Institute of Standards and Technology (NIST) Biometrics Usability team to examine the impact on fingerprint capture performance of angling the fingerprint scanners on the existing counter heights to accommodate the upcoming pilot testing. The NIST Biometrics Usability group's study1 was specifically designed to answer the question: Given the current counter heights in US-VISIT facilities, what is the “best” angle to position the fingerprint scanner? The study included three metrics: 1. Efficiency – the time to complete the tasks. Does the angle of the fingerprint scanner affect the time required to capture fingerprint images? 2. Effectiveness – how good are the prints? Does the angle affect the quality of the captured images? 3. Satisfaction – comfort. Do users prefer a particular fingerprint scanner angle?
Download or read book Specification for Interoperability Testing of Contactless Fingerprint Acquisition Devices written by John Libert and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 their devices to perform an integral role in the collection of measurements by which their device will be evaluated by the certifying authority or other stakeholders. The NIST Fingerprint Registration and Comparison Tool (NFRaCT) enables interested parties seeking testing for certification to collect fingerprint images and performance measurements using the NFRaCT and provide those measurements to the certifying authority for analysis and evaluation without requiring the exchange of any underlying fingerprint images. The protocol provides flexibility in that device performance can be evaluated and validated using live fingerprint impressions or three-dimensional (3D) fingerprint target artifacts.

Download or read book Usability Testing of Ten Print Fingerprint Capture written by Mary Theofanos and published by . This book was released on 2007-08-01 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dept. of Homeland Security (DHS) & the U.S. Visitor & Immigrant Status Indicator Technology (US-VISIT) program are migrating from a 2-print capture process (left & right index fingers) to a 10-print slap fingerprint capture process (all fingers on both hands). A usability test was performed to evaluate the time required to acquire a 10-print slap fingerprint image. This report presents the results of a study that examined the 10-print collection process. The study was designed to answer 3 questions: (1) How long does it take to capture a 10-print image? (2) What is the impact of instructional mode (poster, verbal or video) on user performance? (3) What are the frequency & nature of the errors that occur in this process? Illustrations.
Download or read book Guidance for Evaluating Contactless Fingerprint Acquisition Devices written by John Libert and published by . This book was released on 2018 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document details efforts undertaken by the National Institute of Standards and Technology (NIST) to develop measurements and a protocol for the evaluation of contactless (touchless) fingerprint acquisition devices. Contactless fingerprint capture differs fundamentally from legacy contact fingerprinting methods, and poses novel problems for image quality evaluation and challenges relative to interoperability with contact fingerprints that populate large repositories maintained by law enforcement and Federal Government organizations. For contact acquisition, the fingerprint impression is a first-order transfer of the 3D friction ridge structure to the recording surface. The third dimension of the curved finger surface is effectively removed by pressure against the planar recording surface. The 3D topography of the ridges and furrows are transferred with low ambiguity to the recording surface as dark ridges (points of contact) and lighter furrows (lesser or no contact). Contactless images by comparison, in most cases, are third-order renderings of an original photographic representation, itself a 2D optical projection of the 3D structure of the finger. The appearance of this projection is subject to variability as low- or moderately-controlled lighting interacts with the 3D geometry of the finger, the friction ridge structure superimposed on the finger, and the geometry of the presentation of the finger to the contactless device. The photograph must then be subjected to various image processing methods to infer the ridge structure for rendering as a fingerprint similar in appearance to legacy contact captures. The rendering process is the source of numerous errors relative to contact captures. Despite problems with image quality, this early study finds contactless fingerprints of the devices examined to be usable in some applications, with qualifications, including one- to-many matching against small databases.

Download or read book Repeatability of Contactless and Contact Fingerprint Capture written by John M. Libert and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 fingerprint by making contact with it also introduces a certain amount of physical distortion to the finger being pressed against the collection medium. It is hypothesized that because contactless collection devices do not need to make physical contact with the finger bring captured, the resulting collections from contactless devices are expected to have no mechanical deformation introduced to the finger and provide better intraoperability and as well as better consistency between captures from the same device.This hypothesis was rejected in that observations in this study showed that contact collection devices have more consistency and less variability between successive captures using the same device.
