"Forensic document examination is the study of physical evidence and physical evidence cannot lie. Only its interpretation can err. Only the failure to find it, or to hear its true testimony can deprive it of its value." - Roy Huber, author A definitive review of handwriting identification, this book presents, in a general manner, how to approach document examination and then, in particular, how to apply handwriting identification to the document. Types of handwriting are discussed in detail. For the first time in the field of questioned document examination, Handwriting Identification: Facts and Fundamentals consolidates the pertinent information from published and unpublished sources respecting writing, that is essential to the expansion of a practitioner's general knowledge of handwriting identification and to the proper education of novices. Written in a question and answer format, the book suggests some of the questions that one might ask of an examiner and provides the answers that knowledgeable and competent examiners should be expected to give. This book is a valuable addition to law libraries and to every practicing document examiner, as well as every lawyer handling cases in which the authenticity of handwriting might be disputed.

The examination of handwriting and signatures has a long and established history as a forensic discipline. With the advancement of technology in the use of digital tablets for signature capture, changes in handwriting examination are necessary. Other changes in handwriting, such as in increase in printed writing styles and the decrease in handwriting training in schools necessitates a re-examination of forensic handwriting identification problems. This text takes a fresh and modern look at handwriting examination as it pertains to forensic, legal, and criminal justice applications.
This book has the primary goal of presenting and discussing some recent advances and ongoing developments in the Handwritten Text Recognition (HTR) field, resulting from works done on different HTR-related topics for the achievement of more accurate and efficient recognition systems. Nowadays, there is an enormous worldwide interest in HTR systems, which is mostly driven by the emergence of new portable devices incorporating handwriting recognition functions. Others interests are the biometric identification systems employing handwritten signatures, as well as the requirements from cultural heritage institutions like historical archives and libraries in order to preserve their large collections of historical (handwritten) documents. The book is organized into two sections: the first one is mainly devoted to describing the current state-of-the-art applications in HTR and the last advances in some of the steps involved in HTR workflow (that is, preprocessing, feature extraction, recognition engines, etc.), whereas the second focuses more on some relevant HTR-related applications.In more depth, the first part offers an overview of the current state-of-the-art applications of HTR technology and introduces the new challenges and research opportunities in the field. Besides, it provides a general discussion of currently ongoing approaches towards solving the underlying search problems on the basis of existing methods for HTR in terms of both accuracy and efficiency. In particular, there are chapters especially focused on image thresholding and enhancement, text image preprocessing techniques for historical handwritten documents and feature extraction methods for HTR. Likewise, in line with the breakout success of Deep Neural Networks (DNNs) in the field, a whole chapter is devoted to describing the designing of HTR systems based on DNNs. Finally, a chapter listing the most used benchmarking datasets for HTR is also included, providing detailed information about which types of HTR systems (on/offline) and features are commonly considered for each of them.In the second part, several systems -- also developed on the basis of the fundamental concepts and general approaches outlined in the first part -- are described for several HTR-related applications. Presented in the corresponding chapters, these applications cover a wide spectrum of scenarios: mathematical formulae recognition, scripting language recognition, multimodal handwriting-speech recognition, hardware design for online HTR, student performance evaluation through handwriting analysis, performance evaluation methods, keyword spotting, and handwritten signature verification systems.Last but not least, it is important to remark that to a large extent, this book is the result of works carried out by several researchers in the Handwritten Text Recognition field.Therefore, it owes credit to these researchers that have directly contributed to their ideas, discussions and technical collaborations, and in general who, in one manner or another, have made it possible.
Explains how to use handwriting analysis to interpret people's character traits, personalities, and backgrounds, and examines the handwriting of such dangerous individuals as Ted Bundy, Jack the Ripper, and Osama bin Laden.

This second edition of Bates' I.S.Q.D. updates and expands the previous volume and continues to reflect the scientific method of detecting whether a writing is genuine or forged. This book serves as a guide and reference for the investigator or examiner in matters relating to the identification of handwriting. In and of itself, it is not intended in any way to qualify an individual as an expert, but is to be used as a tool with which to assist in the discovery and proof of fact. These are the two essential parts of handwriting comparison. Divided into three sections, the book presents the twelve points of comparison and the method of making a scientific analysis, a guide for presentation of facts in court, and a sample demonstration of the discovery and proof of fact. Once these points of comparison have been determined, the examiner has a basis from which to offer an opinion. This book can be used as a primary text in questioned document examinations, and will be an excellent resource for law enforcement agencies, including private and industrial investigative groups
