METHOD FOR VERIFYING THE AUTHENTICITY OF DOCUMENTS

摘要

The invention relates to a method for verifying the authenticity of documents, especially that of bank notes, valuable documents or security documents, on the basis of authenticity criteria. The aim of the invention is to provide a more reliable manner of verifying the authenticity of a document. In order to achieve this, at least two different levels of authenticity with at least one authenticity criterion respectively are provided. Each individual authenticity level differs from the other in at least one authenticity criterion. One authenticity level is selected from the various authenticity levels and the document is verified on the basis of the authenticity criteria of the selected authenticity level. The selected authenticity level is allocated to said document if it fulfils the authenticity criteria thereof. The inventive method increases the reliability of the verification of document authenticity as it enables documents to be detected which satisfy higher authenticity requirements i.e. stricter authenticity criteria than other documents, and which are thus more likely to be authentic.
