Method for backtracking of documents, particularly of value documents and falsification of value documents, involves detecting data of document by physical measurement techniques

摘要

The method involves detecting data of a document by physical measurement techniques. One or multiple safety features of the document are determined from the detected data. The individual characteristics of the document are compared with the individual characteristics of other documents. The individual characteristics of other documents are stored in a storage device. The data is determined by an optical measuring process. An independent claim is also included for a device for backtracking of documents, particularly of value documents and falsification of value documents.
