Abstract

Forgery of personal identity documents is an integral part of organized crime, the precondition of international smuggling drugs, weapons and other goods, illegal immigration, human trafficking, terrorism, mobility, fraud, money laundering. These sides of organized crime puts the greatest threat to internal security of the EU, while the harm to made to the economy, including distortions of the domestic market, can reach hundreds of billions of euros. Therefore, expeditious inspection of personal identity documents continues to remain a very important issue for law enforcement bodies (officers of migration, police, State Border Guard Service). This research deals with the authenticity inspection of personal identity document - passport data page - which is based on non-destructive testing - holographic interferometry methods and the analysis of thermal behaviour impact on the MPR data page surface deformation. Original and forged passports were investigated, thermal load parameters on the data page and its fixation conditions in a special holder were determined. The analysis of the obtained holographic interferograms allowed confirming the hypothesis claims that the character of surface deformation of forged MPR data page significantly differs from the character of original MPR data. Computational model of MPR data page thermal behaviour was developed. Simulation of the process of data page surface deformation with the applied thermal loading was carried out. Theoretical and experimental results confirming the application possibility of non-destructive testing methodology for determining authenticity of the passports were obtained.
