Reviews
“The beauty of this seminal work of Dr. Sumit, Dr. Surbhi, & Mr. Anubhav is coming out with three books at one go that together weave the entire length and breadth of the field of questioned documents examination. The books [along with their sister volumes] serve not only as a repository of knowledge but also as a guide to navigating the intricate landscape of forensic document examination. . . . A comprehensive exploration of contemporary methodologies, tools, and techniques that enhance the know-how of the examination of questioned documents.”
—From the Foreword by Dr. Henry Lee, Founder & Emeritus Professor, Institute of Forensic Science, University New Haven, Connecticut, USA; Commissioner (ret), Connecticut Department of Public Safety; Director & Chief Criminalist (ret) State Police Forensic Laboratory of Public SafetyDirector & Chief Criminalist (ret) State Police Forensic Laboratory


Modern document experts need both old-fashioned tricks like studying ink under a microscope and new tools like computer programs that spot tiny changes in images to uncover what really happened. This new volume, Forensic Examination of Altered and Tampered Documents, draws on decades of casework, pioneering research, and pivotal legal rulings to present a seamless framework for tackling every form of questioned document, whether it’s a scanned PDF, an e-mail printout, or a government ID embedded with holograms.

Presenting a basic understanding of standard examination processes, the book offers practical techniques for authenticating digitally captured signatures and writings, using multispectral and pattern-recognition tools to uncover hidden changes, exploring electronic file metadata, and verifying the features of security documents. Ethical guidelines, tips for writing clear and effective reports, and strategies for presenting findings in court can be found throughout the book, ensuring that technical discoveries hold up under legal, moral, and professional examination.

Chapters cover the examination of digitally captured signatures and writings, image processing in questioned documents, digital and electronic document examination, security documents, forensic stylistics in handwritten and e-documents, ethical and professional standards, report writing and evidence presentations in questioned document examination, courtroom testimony and landmark judgments, and emerging trends and future directions in forensic handwriting examination.

This volume, in conjunction with its sister volumes, Forensic Examination of Questioned Documents and Advances in Forensic Examination and Reporting of Questioned Documents Cases offer a comprehensive collection that covers the basics of forensic document science along with methods, techniques, and cutting-edge advances, offers the practical guidance necessary to elevate your work to the highest scientific and ethical standards.
