Abstract (en)
[origin: EP0440021A2] The method for identifying franking and post-marking machines proposes the additional printing of an unfalsifiable identification feature. This feature is obtained from the interlinking of machine parameters with the date and the charge value to be printed and, if appropriate, numbers of the publicity block by means of a cryptographic algorithm. <IMAGE>
