Forensic document examination is an essential aspect of modern-day investigations, involving the analysis of documents to determine their authenticity and origin. This module introduces key concepts of digital forensic document examination, focusing on the basics of detecting forgery, examining handwriting, and utilizing non-invasive tools for digital analysis. As digital documents become more prevalent, the skills to accurately assess their validity are critical for forensic experts. Forensic document examination (FDE) plays an important role in numerous legal, business, and historical contexts. It is used to determine whether a document is genuine, whether it has been altered, or whether the claimed authorship is accurate. With the increasing shift from traditional ink-and-paper documents to digital formats, the scope of FDE has expanded significantly to include digital forensic techniques, which are crucial for modern-day investigations.
