Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project was to increase understanding of the discriminative power of friction ridge patterns using computational approaches. A three-pronged approach was taken: (i) a study of the fingerprints of twins using automatic fingerprint matching algorithms, (ii) modeling the probability distribution of fingerprints from which the probability of random correspondence of fingerprints is determined - this is the generative approach to individuality, and (iii) new algorithms for feature extraction and classification are used to determine error probabilities-- this is the discriminative approach to individuality. The main conclusion of the twins' study is that although friction ridge patterns of twins are more similar than in the general population, they are still discriminable. The twins' findings strengthen the argument of fingerprint individuality. Taking the generative approach the individuality of a forensic modality can also be established by computing the probability of random correspondence of two pieces of evidence directly from the underlying distribution of evidence features. The distribution can be modeled as a mixture distribution whose parameters can be determined from a database of fingerprints. First a model consisting of only minutiae was considered and then expanded to include ridge information as well. It was found that the probability of random correspondence with ridges is much lower than with minutiae alone. These probabilities were quantified in terms of the available number of minutiae and ridge points. In the discriminative approach two new approaches to automatic fingerprint comparison were developed: use of likelihood methods instead of ROC-based methods, and using ridge information in addition to minutiae in fingerprint comparison. Both discriminative studies point to improved performance particularly when there are fewer minutiae available in the input as in the case of latent prints.

Download or read book The Forensic Analysis Comparison and Evaluation of Friction Ridge Skin Impressions written by Dan G. Perkins and published by John Wiley & Sons. This book was released on 2022-07-25 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE FORENSIC ANALYSIS, COMPARISON AND EVALUATION OF FRICTION RIDGE SKIN IMPRESSIONS An accessible, highly practical introduction to the ACE framework fingerprint examiners use to analyse, compare and evaluate friction ridge skin impressions. When friction ridge skin (the skin on the undersides of the hands and feet) contacts a surface an impression of it may be left behind. Impressions that are left inadvertently, for example at a scene where a crime is alleged to have been committed are known as ‘marks’. Impressions taken intentionally from a person, for example as a result of their arrest are known as ‘prints’. The Forensic Analysis, Comparison and Evaluation of Friction Ridge Skin Impressions offers step-by-step instruction to examiners tasked with identifying people by the marks they leave behind. Assuming no previous knowledge of the subject, this easy-to-use guide breaks down the ACE (Analysis, Comparison and Evaluation) framework into 10 key questions that provide clear guidance on: establishing the most evidentially valuable mark; the type of details the mark may reveal; the effects of distortion; how to determine which area of skin is most likely to have made the mark, and more. Author Dan Perkins draws upon his years of experience to equip fingerprint examiners with the key skills needed to carry out the appropriate analysis, comparison and evaluation of friction ridge skin impressions. Presents a stepwise approach designed for both novice and more experienced fingerprint examiners Discusses all aspects of ACE, including the formation of fingerprints, documentation, suitability, and orientation Contains references to relevant research, real-world case studies, and hundreds of impressions the reader can analyse and compare Includes five detailed appendices covering fabrication, transplantation and forgery, verification, bias, activity level propositions, and errors The Forensic Analysis, Comparison and Evaluation of Friction Ridge Skin Impressions is an indispensable ACE ‘checklist’ for trainees in the field of fingerprint comparison and identification, qualified fingerprint examiners and forensic science students.

Available in PDF, EPUB and Kindle. Book excerpt: The idea of The Fingerprint Sourcebook originated during a meeting in April 2002. Individuals representing the fingerprint, academic, and scientific communities met in Chicago, Illinois, for a day and a half to discuss the state of fingerprint identification with a view toward the challenges raised by Daubert issues. The meeting was a joint project between the International Association for Identification (IAI) and West Virginia University (WVU). One recommendation that came out of that meeting was a suggestion to create a sourcebook for friction ridge examiners, that is, a single source of researched information regarding the subject. This sourcebook would provide educational, training, and research information for the international scientific community.

Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Download or read book Advanced Fingerprint Recognition From 3D Shape to Ridge Detail written by Feng Liu and published by Springer Nature. This book was released on 2020-05-22 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fingerprints are among the most widely used biometric modalities and have been successfully applied in various scenarios. For example, in forensics, fingerprints serve as important legal evidence; and in civilian applications, fingerprints are used for access and attendance control as well as other identity services. Thanks to advances in three-dimensional (3D) and high-resolution imaging technology, it is now feasible to capture 3D or high-resolution fingerprints to provide extra information and go beyond the traditional features such as global ridge patterns and local ridge singularities used in conventional fingerprint recognition tasks. This book presents the state of the art in the acquisition and analysis of 3D and high-resolution fingerprints. Based on the authors’ research, this book focuses on advanced fingerprint recognition using 3D fingerprint features (i.e., finger shape, level 0 features) or high-resolution fingerprint features (i.e., ridge detail, level 3 features). It is a valuable resource for researchers, professionals and graduate students working in the field of computer vision, pattern recognition, security/biometrics practice, as well as interdisciplinary researchers.

Download or read book Courtroom Testimony for Fingerprint Examiners written by Hillary Moses Daluz and published by CRC Press. This book was released on 2021-08-30 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fingerprint examiners today are expected to develop, research and defend the scientific basis of their conclusions. Recent emphasis placed on scientific rigor and transparency through documentation has created a culture shift in the field. Many examiners are baffled by the resulting cultural, procedural and scientific distinctions, often becoming overwhelmed when required to testify as an expert witness to explain such concepts in the courtroom. Courtroom Testimony for Fingerprint Examiners addresses all aspects of courtroom testimony as the first book to focus solely on testifying on fingerprint evidence as a comparative science. The book is presented in two parts. Section I addresses general expert witnessing for forensic scientists. This serves as a primer for the novice or a review for experienced witnesses covering such topics as the structure of the criminal justice system and federal rules of evidence, the role of the expert witness, testimony as teaching, presenting challenging scientific concepts to the layperson, court preparation, the three phases of expert witness testimony and landmark court decisions that have shaped the modern landscape of forensic testimony. Section II focuses on specific issues affecting fingerprint examiners and how to field questions during both direct and cross-examination. While such "hot button" topics are absent from currently available texts, this section pays particular attention to these salient, emerging topics. This includes evidentiary challenges to fingerprint evidence, relevant publications such as the PCAST report, nomenclature and standards development, issues surrounding cognitive bias and subjectivity, probability models, error rates and cases of error and how to address issues of minimum point standards in both the empirical and holistic traditions. Both Section I and Section II provide examples and present innovations applicable to latent and tenprint examiners. Features include: Presents a history of fingerprint evidence and current best practices and limits on characterizing fingerprint evidence in court, including appropriate nomenclature Provides current guidelines and recommendations for standards and the courtroom Illustrates how experts can work with attorneys so that the testimony process educates and informs jurors and judges rather than perpetuating an adversarial dynamic Addresses important issues such as cognitive bias, subjectivity, error rates, probability models and ethics As a forensic training instructor for professionals – and previously as a college professor – author Hillary Moses Daluz has spent the past ten years teaching courtroom testimony courses to forensic scientists. Courtroom Testimony for Fingerprint Examiners offers an invaluable resource to forensic scientists, latent print examiners, tenprint examiners, lab personnel in related comparative fields, attorneys, investigative professionals and students enrolled in forensic science university programs.
