John Daugman correctly summarized the state of forensic iris recognition circa 2006 for the book Forensic Human Identification: an Introduction by Thompson (CRC Press, 2006). Iris recognition has limited forensic value, because (unlike fingerprints or DNA, for example) (1) iris patterns are not left behind at crime scenes; (2) and in death the pupil usually dilates significantly, the cornea clouds, and the iris tissue degrades relatively rapidly. (3) Moreover, currently available iris databases are quite small (only a few million digitized samples of iris patterns exist today); and because of the novelty of this biometric, (4) such data currently has no legal or established forensic status as admissible evidence. [Numbers () added.] In the intervening ?15 years, all of Daugman s observations, save one, have been overtaken by events: (1) The advent of ubiquitous high resolution video/photography has led to widespread collection/retention/dissemination of imagery of sufficient resolution for iris recognition. (2) Demonstrations of post-mortem iris recognition have been made. (3) Large iris databases have been constructed. The last issue (4) regarding admissible evidence remains to be resolved. Forensic iris was a topic at the June 2018 Iris Experts Group Meeting1. Key issues discussed there were: measurements and analysis that need to be done to provide the underpinnings for a resolution of the forensic status of iris recognition and the development of documentation for such measurements and analysis that will enable explanation of iris collection and recognition to lay audiences, including those in a courtroom. An important point was that the perceptions of the public and the popular media with respect to biometrics and to iris recognition in particular are frequently inaccurate and must be considered in any development of materials designed to explain iris recognition to the lay public. To help resolve the questions discussed at that meeting, this paper reviews the current state of the art in iris recognition, the perceptions of the public regarding iris recognition, and makes suggestions regarding measurements and analysis that will help enable use of forensic iris in appropriate settings going forward. We welcome comments for the next revision of this document. Please send comments to james.matey@nist.gov.
This report is a part of a series of studies on the topic of face morphing, its relevance and implications as a vulnerability to automated face recognition, and methods to aid in detecting morphs. Expanding on concepts introduced in a study conducted by the Dutch Vehicle Authority, this report presents a methodology and quantitative results on the use of automated one-to-many (1:N) face recognition algorithms as a mechanism to potentially detect the presence of morphs. This report is intended to inform end-users and identity credential issuance entities, especially those that accept user-submitted photos, in understanding how a 1:N search against a centralized database might be used to flag suspicious activity related to face morphing. Our proposed methodology analyzes the rank 1 and rank 2 scores that are returned on candidate lists from searching morph and bona fide photos against both consolidated and unconsolidated galleries of 1.6 million unique subjects under new enrollment and renewal scenarios. Morph classifiers are trained using the rank 1 and 2 score pairs from a number of modern 1:N face recognition algorithms to quantify the utility of these scores in detecting morphs.
WhileEvaluation face recognition research has been perennial and popular since its inception, there has been a marked escalation in this research in recent years due to the confluence of several factors, primarily the development of advanced machine learning algorithms, free and robust software implementations thereof, ever faster GPU processors for running them, vast web-scraped face image databases, open performancePerformance benchmarks, and a vibrant face recognition literature.
This is the second of a series of reports on the performance of face recognition algorithms on faces occluded by protective face masks commonly worn to reduce inhalation and exhalation of viruses. This is a continuous study is being run under the Ongoing Face Recognition Vendor Test (FRVT) executed by the National Institute of Standards and Technology (NIST). In our first report, we tested "pre-pandemic" algorithms that were already submitted to FRVT 1:1 prior to mid-March 2020. This report augments its predecessor with results for more recent algorithms provided to NIST after the COVID-19 pandemic was declared. While we do not have information on whether or not a particular algorithm was designed with face coverings in mind, the results show evidence that a number of developers have adapted their algorithms to support face recognition on subjects potentially wearing face masks. The algorithms tested were one- to-one algorithms submitted to the FRVT 1:1 Verification track. Future editions of this document will also report accuracy of one-to- many algorithms.

Although considerable work has been done in recent years to drive the state of the art in facial recognition towards operation on fully unconstrained imagery, research has always been restricted by a lack of datasets in the public domain. In addition, traditional biometrics experiments such as single image verification and closed set recognition do not adequately evaluate the ways in which unconstrained face recognition systems are used in practice. The IARPA Janus Benchmark-C (IJB-C) face dataset advances the goal of robust unconstrained face recognition, improving upon the previous public domain IJB-B dataset, by increasing dataset size and variability, and by introducing end-to-end protocols that more closely model operational face recognition use cases. IJB-C adds 1,661 new subjects to the 1,870 subjects released in IJB-B, with increased emphasis on occlusion and diversity of subject occupation and geographic origin with the goal of improving representation of the global population. Annotations on IJB-C imagery have been expanded to allow for further covariate analysis, including a spatial occlusion grid to standardize analysis of occlusion. Due to these enhancements, the IJB-C dataset is significantly more challenging than other datasets in the public domain and will advance the state of the art in unconstrained face recognition.
5 Issues Not Yet Fully Addressed by Standards 5.1 Capture Sequence and Cardinality Issues:
BackgroundThe Tattoo Recognition Technology -Evaluation (Tatt-E) was organized by the National Institute of Standards and Technology (NIST) in collaboration with law enforcement to assess and measure the capability of algorithms to perform automated image-based tattoo recognition.Tatt-E is the follow-on to the Tattoo Recognition Technology -Challenge (Tatt-C) 2015 activity [1], which engaged researchers with an open dataset of operationally collected tattoo images and challenge problems to advance image-based tattoo recognition research and development.The Tatt-E activity assesses comparative and absolute accuracy, along with run-time measures on larger, operationally realistic datasets than seen in Tatt-C. Tatt-E Test ActivityThe Tatt-E program was open to participation worldwide.The participation window opened on December 1, 2016, and the submission deadine to the final phase was September 29, 2017.There was no charge to participate.Tatt-E was performed as a large scale empirical evaluation of a total of 12 tattoo recognition algorithms, with participation from two providers -one commercial, MorphoTrak, and one university, the Chinese Academy of Sciences (CAS).The test leveraged large operational datasets comprising tattoo images from law enforcement databases, enabling evaluation with enrollment database sizes of up to 100 000.NIST employed a "lights-out", black-box testing methodology designed to model operational reality where software is shipped and used as-is, without algorithmic training.Core tattoo identification accuracy was baselined over tattoo images used as-is, then traded off against gallery size and search speed.The effects of cropping around the primary tattoo content, skintone, contrast, and tattoo-to-image ratio were assessed, and matching accuracy on sketch images and tattoos collected in the shortwave infrared (SWIR) spectrum are also reported.In addition, performance on algorithmic capability to do tattoo detection and tattoo localization as separate tasks are also documented. Key ResultsKey results for the use cases studied are summarized below.A legend mapping the algorithm letter code to the participating organization is provided in the footer of every page of this report and in Table 1.For the definition of hit rate, true positive detection rate, and localization accuracy, see Section 3. Generally speaking, the higher the hit rate, true positive detection rate, and localization accuracy value, the more accurate the algorithm.
The report describes and presents the results for Text Recognition Algorithm Independent Evaluation (TRAIT) in support of forensic investigations of digital media. These images are of interest to NIST’s partner law enforcement agencies that seek to employ text recognition in investigating serious crimes. This evaluation used images seized in child exploitation investigations. The primary application is the identifcation of previously known victims and suspects, as well as detection of new victims and suspects. The presence of text, for example, on a wall poster or on an item of clothing, may allow a location to be identifed and linked to prior cases. In total, 3 groups took part in this evaluation over three Phases. The evaluation results show that the initial performance of text recognition is low. However, from Phase 1 to Phase 3, the performance of text recognition algorithms has shown signifcant improvement. We hope this evaluation will stir more research in this feld.
Despite the importance of rigorous testing data for evaluating face recognition algorithms, all major publicly available faces-in-the-wild datasets are constrained by the use of a commodity face detector, which limits, among other conditions, pose, occlusion, expression, and illumination variations. In 2015, the NIST IJB-A dataset, which consists of 500 subjects, was released to mitigate these constraints. However, the relatively low number of impostor and genuine matches per split in the IJB-A protocol limits the evaluation of an algorithm at operationally relevant assessment points. This paper builds upon IJB-A and introduces the IARPA Janus Benchmark-B (NIST IJB-B) dataset, a superset of IJB-A. IJB-B consists of 1,845 subjects with human-labeled ground truth face bounding boxes, eye/nose locations, and covariate metadata such as occlusion, facial hair, and skintone for 21,798 still images and 55,026 frames from 7,011 videos. IJB-B was also designed to have a more uniform geographic distribution of subjects across the globe than that of IJB-A. Test protocols for IJB-B represent operational use cases including access point identification, forensic quality media searches, surveillance video searches, and clustering. Finally, all images and videos in IJB-B are published under a Creative Commons distribution license and, therefore, can be freely distributed among the research community.
