This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 ID optimized operational pathway, depending on configuration. Contactless fingerprint imagery from six contactless devices were used, along with mated imagery from two touch-based devices using a block experimental design. Experimental cases were defined for the matching of contactless fingerprint imagery as either probe or biometric reference database, and system matching accuracy measured in terms of false negative identification rate (FNIR). Due to the small data set available, the experiment was not structured to measure false positive error rates. Results showed the viability of using contactless imagery as the biometric reference database, albeit using these images will come at the price of matching accuracy on the Ten-Print matcher (FNIR of 0.5?% worst case for touch devices vs. FNIR of 1.6?% best case for contactless). The Mobile ID matcher seemed to close the gap between contactless and touch with the best performing contactless device in terms of accuracy (D3) performing at an FNIR of 0.8?% while the worst performing touch-to-touch device was measured at FNIR of 0.5?% showing that Mobile ID optimizations may be key in the introduction of contactless into existing matching pathways. Finally, the introduction of contactless imagery did incur a larger throughput penalty on the Ten- Print matcher than it did on the Mobile ID operational matcher.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 images, as well as not being able to consistently capture certain fingers from each hand. This study tests the hypothesis that eliminating certain error prone fingers, or eliminating some of the periphery of all fingerprint images, may yield an improvement in the matcher s ability to make an identification as well as possibly improving the service time from the matcher.
Download or read book Effect of Image Size and Compression on One to one Fingerprint Matching written by and published by . This book was released on 2005 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: NIST has conducted testing of one-to-one fingerprint matching systems to evaluate the effect of image size and compression on the accuracy of the one-to-one matching process. Images from three live-scan fingerprint scanners collected by the Departments of State and Homeland Security were used as test samples. Image sizes from 368 pixels by 368 pixels down to 180 pixels by 180 pixels were tested and compression ratios from no compression up to 30:1 were tested. Three commercial fingerprint-matching systems were used in the test. The results of the study show that image cropping quickly degrade matcher performance. Compression degrades matcher performance more slowly and may increase performance for compression ratios of up to 15:1. The conclusion from this study is that Image sizes below 320 pixels by 320 pixels should not be used. Image compression in the range up 20:1 produces minimal negative effects on fingerprint matching accuracy.

Download or read book Interoperability Assessment 2019 written by John Libert and published by . This book was released on 2020 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Federal Employees were collected using both contact and contactless acquisition devices, including both stationary devices and mobile smartphone devices. Match scores from two different matchers were used to calculate False Negative Identification Rate (FNIR) and False Positive Identification Rate (FPIR) at two operational thresholds appropriate to each of the matchers. These values are displayed in graphical form across eight devices for each of ten finger combinations. Overall error performance is compared via Area Under Curve across devices for each of ten finger combinations as well as across finger combinations separately for each of the eight devices. Contact-to-contact interoperability remains superior to contactless-to-contact, but multiple finger combinations improve match performance of contactless devices.
Download or read book Experiments in Parallel Fingerprint Matching Architectural Implications for Large Scale Fingerprint Matching Evaluation Systems written by U.s. Department of Commerce and published by CreateSpace. This book was released on 2014-03-04 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for very large fingerprint benchmarks to test the efficacy of emerging commercial technologies for fingerprint minutia detection, matching, compression, and retrieval is well recognized. It is driving more intensive use of networked parallel processing clusters. This report demonstrated the feasibility of a parallel fingerprint matching hosted in the NIST Data Flow System Version II middleware layer, and identified specific hardware and software constraints that cause performance problems when introducing parallelism. The starting point consisted in a standalone matcher that takes two fingerprint images as an input and provides a matching score by using the well-known Bozorth fingerprint matcher. The publicly available NIST Special Database 14 and tools were used for matching and in order to handle fingerprint images and perform the minutia detection and print matching. Scalability to about 100 compute cores was shown using conventional gigabit Ethernet connectivity.

Download or read book Introducing Biometric Technology in Elections written by Peter Wolf and published by International Institute for Democracy and Electoral Assistance (International IDEA). This book was released on 2017-06-20 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: A credible voter register gives legitimacy to the electoral process and helps prevent electoral fraud. However, voter registration remains a complex and contested task. It is one of the most important activities that an electoral management body needs to conduct, but it is also one of the most costly in terms of both time and resources. Many countries that face challenges in creating an accurate voter register are considering reforming their voter registration systems through the introduction of biometric technologies. The drive towards biometrics has been facilitated by its largely apolitical nature. Investing in high-tech solutions allows stakeholders to demonstrate their commitment to resolving electoral problems. At the same time, expectations on biometric solutions may be exaggerated. This guide provides an overview of key concepts and considerations for all stakeholders involved in discussions about the application of biometrics in elections, both for voter registration before an election and for voter verification at polling stations on election day.

Book excerpt: Biometric authentication is increasingly gaining popularity in a large spectrum ofapplications,rangingfromgovernmentprograms(e. g. ,nationalIDcards,visas for international travel,and the ?ght against terrorism) to personal applications such as logical and physical access control. Although a number of e?ective - lutions are currently available, new approaches and techniques are necessary to overcomesomeofthelimitationsofcurrentsystemsandtoopenupnewfrontiers in biometric research and development. The 30 papers presented at Biometric Authentication Workshop 2004 (BioAW 2004) provided a snapshot of current research in biometrics, and identify some new trends. This volume is composed of?vesections:facerecognition,?ngerprintrecognition,templateprotectionand security, other biometrics, and fusion and multimodal biometrics. For classical biometrics like ?ngerprint and face recognition, most of the papers in Sect. 1 and 2 address robustness issues in order to make the biometric systems work in suboptimal conditions: examples include face detection and recognition - der uncontrolled lighting and pose variations, and ?ngerprint matching in the case of severe skin distortion. Benchmarking and interoperability of sensors and liveness detection are also topics of primary interest for ?ngerprint-based s- tems. Biometrics alone is not the solution for complex security problems. Some of the papers in Sect. 3 focus on designing secure systems; this requires dealing with safe template storage, checking data integrity, and implementing solutions in a privacy-preserving fashion. The match-on-tokens approach, provided that current accuracy and cost limitations can be satisfactorily solved by using new algorithms and hardware, is certainly a promising alternative. The use of new biometric indicators like eye movement, 3D ?nger shape, and soft traits (e. g.
