Abstract (en)
The method involves signing a digital representation of reference information with a cryptographic key, so as to obtain signed information, and forming a set of information including the signed information. The set of information is converted into a machine-readable code (12), and the code is printed on a document (10), where the cryptographic key is a secret key or a private key. Another machine-readable code (13) corresponding to the digital representation of the reference information is printed on the document.
