The invention relates to a method for examining the authenticity of non-electronic documents, whereby a non electronic document comprises a document identifier, text and/or graphic user information, at least implicite information on the document user and a signature which is a coded first test code calculated by means of a selected test function from the document identifier and the text and/or graphic user information. According to the invention, the document identifier, the text and/or graphic user information and the signature are scanned. A second test code is calculated from the scanned document identifier and the scanned text and/or graphic user information by means of the selected test function. The scanned signature is decoded in order to determine the first test code by using the at least implicite information on the document user. The first and second test codes are compared for consistency. |
