Book Description
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.

Book Description
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.

Book Description
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.

Book Description
The National Institute of Justice (NIJ) Sensor, Surveillance, and Biometric Technologies (SSBT) Center of Excellence (CoE) has undertaken an evaluation of fingerprint data gathered from traditional two dimensional (2D) contact-based fingerprints devices and techniques versus fingerprint data generated by next-generation three dimensional (3D) contactless fingerprint scanners. The evaluation investigates the comparative match performance of legacy/livescan fingerprint (LFP) data and contactless fingerprint (CFP) data, for the purposes of exploring interoperability, technology viability, and challenges to operational deployment of next-generation contactless fingerprint systems. The principal work was performed by Azimuth Inc., as a subcontractor for ManTech International Corporation, under the SSBT CoE program. The work was also performed in collaboration with the Department of Defense (DoD), Director of Defense Biometrics & Forensics and the Biometrics Identity Management Agency (BIMA). The data analysis was conducted using a fingerprint dataset collected by West Virginia University (WVU). The dataset is available for use by third-party research organizations upon request. Fingerprint data was collected from 500 subjects ...

Book Description
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.

Book Description
This book constitutes the thoroughly refereed joint post proceedings of two international workshops, the 7th International Workshop on Data Privacy Management, DPM 2012, and the 5th International Workshop on Autonomous and Spontaneous Security, SETOP 2012, held in Pisa, Italy, in September 2012. The volume contains 13 full papers selected out of 31 submissions and 3 keynote lectures from the DPM workshop and 10 papers selected among numerous submissions from the SETOP workshop. The contributions from DPM cover topics from location privacy, citizens' privacy, privacy, authentication with anonymity, privacy in distributed systems, privacy policies, and automated privacy enforcement. The SETOP contributions provide a unique view of ongoing security research work in a number of emerging environments that are becoming part of the global ICT infrastructure, from content-centric to mobile and wireless networks. Also, some of them cover the key role of run-time enforcement in process and service security. The topics of SETOP papers include: security policy deployment; distributed intrusion detection; autonomous and spontaneous response; privacy policies; secure localization; context aware and ubiquitous computing; identity management.
