Abstract

Under the effect of globalization and constantly increasing number of persons crossing state borders reliable authenticity assessment of personal identity documents is of crucial importance. As for inspection of the document only a few minutes are allocated, in the presence of signs of falsification or counterfeiting effective methods based on the application of technical devices are necessary. The research presents a method for structural integrity verification of a data sheet of multilayer structure polycarbonate - teslin by the analysis of heat exchange process in it. The change of physical parameters (thermal conductivity) at the mechanically damaged and nondamaged zones of the data sheet was experimentally researched. Mathematical model of heat exchange process through the thickness of the data sheet was built. Simulation results of the process indicate that difference of temperature on the sheet's surface is sufficient for detection by modern devices, its duration and heating temperature are reasonable for practical implementation of the method in inspection of travel documents.
