1. A Method for securing an object, comprising:
a step of encoding a first message in a two-dimensional barcode, the first message comprising at least header identifying a resource of a certification and a signature produced by means of this resource;
a step of generating a fragile anti-copy mark encoding a second message representative of the signature produced, the fragile anti-copy mark is configured for degradation during copying thereof, and said fragile anti-copy mark further includes redundancies configured such that the second message is readable, despite said degradation; and
a step of marking the object with the first 2D barcode and with the fragile anti-copy mark.
