Document authenticity analysis is a forensic examination process used to determine whether a document is genuine, altered, forged, or fabricated. It involves the detailed examination of a document's physical and visual characteristics to identify signs of tampering, counterfeiting, or unauthorized modifications. The primary objective is to verify the originality and integrity of documents used for legal, financial, administrative, or investigative purposes.

Forensic document examiners evaluate various elements, including handwriting, signatures, ink, paper quality, printing methods, stamps, seals, erasures, alterations, overwriting, and security features. Advanced forensic tools such as ultraviolet (UV) light, infrared imaging, microscopes, digital enhancement systems, and chemical analysis techniques are used to detect hidden changes and inconsistencies that are not visible to the naked eye.
