erasures in questioned documents fraud, white-collar crime, magic erasable writing instrument ink, VSC-6000/HS, questioned documents, forensic scienceAbstract
A variety of crucial and legitimate documents, including negotiable instruments like demand drafts, fixed deposit receipts, and cheques, can be used as tools for criminal activity to perpetrate document fraud by erasing text and changing it. Despite the many forms of research that have already been conducted over the years, there is a need to gather the fragmented knowledge that has been available regarding document fraud through erasure and erasable writing instrument ink. As a result, an effort is made in this review to examine literature that has represented its legal values and validate it in light of existing literature and published research studies to shed light on the procedures and methods used to remove the original writing from the forensic questioned document. This will aid in the detection, investigation, and prevention of document fraud by banks, insurance companies, and law enforcement agencies, as well as increase public awareness.
