摘要:AbstractThis work deals with using a novel approach for securing and dating printed documents, which will detect any forging crime present. In this respect, the coded dots matrices (machine identification code (MIC)) for the used printers are extracted via a binary system of base 2 (0, 1). The UV ink used in the printing process is prepared from novel fluorescence compounds together with polyvinyl alcohol. Different Xerox models of color laser printers are used for printing the document designs. The data obtained reveal that the investigated approach is succeeded in specifying the date of the printing process together with translating the embedded data of the printer to visible information, which can be tracked under a UV lamp. This innovative approach will assist workers in examining the questioned document by specifying the authorized date and position of printed documents from the MIC.A novel approach for securing and dating printed documentsis developed to detect any forging crime taking place. In this respect, the coded dots matrices (machine identi‐fication code, MIC) for the used printers are extracted via a binary system of base 2 (0,1) together with fluorescent UV ink.
