Abstract

The manipulation of documents remains a common tool for fraudulent activities, encompassing disputed signatures, threatening letters, counterfeit currency, false medical documents, cloned cheques, and forged security documents. With technological advancements, document creation has evolved from manual handwriting to computer-generated formats, employing various devices such as printers, photocopiers, scanners, and multifunctional devices globally. Forensic document examiners grapple with these challenges, and ongoing efforts are dedicated to addressing them. This study provides a comprehensive review of publications from the past decade, focusing on dating studies, ink and paper analysis, examination of writing and printing inks, ink analysis of questioned documents, and research on intersecting lines. The central emphasis lies on the utilization of Infrared and Raman spectroscopy within the domain of Vibrational spectroscopy. The review also highlights current trends, major challenges, and the effective application of chemometric approaches in this field.

红外光谱和拉曼光谱与化学计量学方法在可疑文件分析中的结合：法医应用

篡改文件仍然是欺诈活动的常见手段，包括有争议的签名、恐吓信、假币、假医疗文件、克隆支票和伪造安全文件。随着技术的进步，文件制作已从手工手写演变为计算机生成格式，在全球范围内使用各种设备，如打印机、复印机、扫描仪和多功能设备。法证文件检验人员努力应对这些挑战，并不断致力于解决这些问题。本研究全面回顾了过去十年的出版物，重点关注年代研究、油墨和纸张分析、书写和印刷油墨检查、可疑文件的油墨分析以及交叉线研究。重点在于振动光谱学领域中红外和拉曼光谱的应用。该综述还强调了当前的趋势、主要挑战以及化学计量学方法在该领域的有效应用。
