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.

Fingerprints: Analysis and Understanding the Science, Second Edition is a thorough update of Mark Hawthorne's classic written by two professionals with combined experience not only in crime scene investigations but also as court-recognized experts in latent print examination. Designed as a concise text to cover the fundamental techniques and principles of obtaining and analyzing latent fingerprint evidence, the book is laid out and written in an easy to understand format for those front-line professionals collecting and analyzing fingerprint evidence. Over time, the degree of sophistication and education on fingerprints and friction ridge analysis has increased. Ultimately, through scientific study by pioneers in the field, the composition of friction skin soon became evident: that it could be used as a unique identifier of individuals. Now, fingerprints and footprints as unique identifiers—and their use in criminal cases—have become commonplace and an essential component of criminal investigation with most cases involving some component of fingerprint evidence. Divided into two parts, the book begins with the basics of analysis, providing a brief history, systematic methods of identification, fingerprint pattern types and their associated terminologies and current classifications. The second part of the book discusses the identification and presentation of evidence in the courtroom, demonstrating both the traditional, manual method of lifting prints and the newer techniques for automated and live scans. Coverage provides instruction on searching and developing latent prints, storage, and comparison of prints.New to this edition are updated techniques on collecting and preserving fingerprint evidence—including packaging and maintaining chain of custody. More detailed documentation processes, and additional chemical and lifting techniques, are described including use of light sources, latent backing cards and lifting material, casting material, ten print cards, and the enhancement of prints in blood. A discussion of laboratory equipment and comparison tools, the addition of photography techniques, and recent courtroom challenges to fingerprint evidence is also presented.Fingerprints, Second Edition will provide a hands-on, fresh look at the most commonly utilized evidence found at crime scenes: fingerprints. The book will provide law enforcement, crime scene personnel and students just such an opportunity to easily understand and grasp the concepts, and relevant issues, associated with friction skin and fingerprint evidence.

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.

Fingerprints have provided a valuable method of personal identification in forensic science and criminal investigations for more than 100 years. Fingerprints left at crime scenes generally are latent prints—unintentional reproductions of the arrangement of ridges on the skin made by the transfer of materials (such as amino acids, proteins, polypeptides, and salts) to a surface. Palms and the soles of feet also have friction ridge skin that can leave latent prints. The examination of a latent print consists of a series of steps involving a comparison of the latent print to a known (or exemplar) print. Courts have accepted latent print evidence for the past century. However, several high-profile cases in the United States and abroad have highlighted the fact that human errors can occur, and litigation and expressions of concern over the evidentiary reliability of latent print examinations and other forensic identification procedures has increased in the last decade. This book discusses latent print examinations in detail, and provides methods to improving the practice through a systems approach.

Overview Biometric recognition refers to the use of distinctive physiological and behavioral character- tics (e. g., fingerprints, face, hang geometry, iris, gait, signature), called biometric identifiers or simply biometrics, for automatically recognizing a person. Questions such as “Is this person authorized to enter the facility?”, “Is this individual entitled to access the privileged infor- tion?”, and “Did this person previously apply for a job?” are routinely asked in a variety of organizations in both public and private sectors. Because biometric identifiers cannot be easily misplaced, forged, or shared, they are considered more reliable for person recognition than traditional token- (e. g., keys) or knowledge- (e. g., password) based methods. Biometric recognition can provide better security, higher efficiency, and increased user convenience. It is for these reasons that biometric systems are being either increasingly deployed or evaluated in a large number of government (e. g., welfare disbursement, national ID card, issuing of driver's license) and civilian (e. g., computer network logon, automatic teller machine, cellular phone, Web access, smartcard) applications. A number of biometric technologies have been developed and several of them are being used in a variety of applications. Among these, fingerprints, face, iris, speech, and hand - ometry are the ones that are most commonly used. Each biometric has its strengths and we- nesses and the choice of a particular biometric typically depends on the requirements of an application.

“No two fingerprints are alike,” or so it goes. For nearly a hundred years fingerprints have represented definitive proof of individual identity in our society. We trust them to tell us who committed a crime, whether a criminal record exists, and how to resolve questions of disputed identity.But in Suspect Identities, Simon Cole reveals that the history of criminal identification is far murkier than we have been led to believe. Cole traces the modern system of fingerprint identification to the nineteenth-century bureaucratic state, and its desire to track and control increasingly mobile, diverse populations whose race or ethnicity made them suspect in the eyes of authorities. In an intriguing history that traverses the globe, taking us to India, Argentina, France, England, and the United States, Cole excavates the forgotten history of criminal identification—from photography to exotic anthropometric systems based on measuring body parts, from fingerprinting to DNA typing. He reveals how fingerprinting ultimately won the trust of the public and the law only after a long battle against rival identification systems.As we rush headlong into the era of genetic identification, and as fingerprint errors are being exposed, this history uncovers the fascinating interplay of our elusive individuality, police and state power, and the quest for scientific certainty. Suspect Identities offers a necessary corrective to blind faith in the infallibility of technology, and a compelling look at its role in defining each of us.

The science of fingerprint identification isn‘t always cut and dry. This book examines the latest methods and techniques in the science of friction ridge identification, or ridgeology. The author examines every facet of the discipline, from the history of friction ridge identification to the scientific basis and the various steps of the identification process. The book, which features several detailed illustrations and photographs, also includes a new method for Palmar Flexion Crease Identification (palm lines) designed by the author and which has helped solve several criminal cases where fingerprints were not available.
