With the optimization of printing technology and the advent of the era of universal printing, the number of cases involving the traceability of laser printed document is increasing and the complexity of cases is by no means the past.Printers and copiers have become an important medium for governments, companies and individuals to exchange information.Printers and photocopiers can produce many documents such as contracts, bills, materials, certificates, etc., and the resulting criminal activities are endless.When authenticating printed document, examiners usually conduct analysis from both morphological and physical and chemical properties.But in principle, there is no rich experience and sufficient samples in actual cases, the success rate of identifying the authenticity of documents, determining the way in which documents are printed and identifying the source of documents is low, and some methods may also damage the documents under investigation.However, there are few integrated studies on traceability methods.Based on this, this paper reviews the existing digital methods and concludes with an analysis of the development trends of document traceability, in an attempt to provide ideas and references for forensic experts.
