Abstract


In recent years, when rapid growth of the number of people crossing state borders is observed it is very im-portant to identify the authenticity of identity documents. Therefore it is becoming very important the impact of both the human factor and the role of application of appropriate technical measures and new methods on the possibility to detect partial changes in the document or forged in whole documents at the stage of primary inspection. This research is dedicated to the identity document - passport data page authenticity tests which are based on non-destructive testing - holographic interferometry methods and the determination of passport data page thermal expansion effect on the surface deformation. Tests were performed with original and forged passports, the data page fixing conditions in a special holder, and thermal load parameters were deter-mined. The obtained results in the form of holographic interferograms confirmed the hypothesis claims that sur-face deformation of the data page in counterfeit passport is clearly different from the original passport‘s data page. The obtained experimental results confirm the possibility to apply the selected non-destructive testing methodology for determining authenticity of the passports.
