Abstract
The method (100) for securing an object comprises: a step of encoding a first message (301) in a two-dimensional barcode (303), the first message comprising at least a header identifying a certification resource and a signature produced by means of this resource; a step of generating a fragile anti-copy mark (304) encoding a second message (302) representative of the signature produced, the second message comprising redundancies; and a step of marking the object with the first 2D barcode and the fragile anti-copy mark.

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.
A device for securing an object, comprising:
- a means for encoding a first message in a 2D barcode, the first message comprising at least a header identifying a resource of a certification and a signature produced by means of this resource;
- a means for 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 means for marking the object with the first 2D barcode and the with fragile anti-copy mark.
A method for authenticating an object, comprising:
- a step of reading a 2D barcode to obtain a first message comprising a header identifying a resource of a certification and a signature produced by means of this resource;
- a step of calculating an element representative of the hash of the signature produced and/or of the signature produced;
- a step of reading a fragile anti-copy mark to obtain 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;
- a first step of comparing the representative element read with the representative element calculated;
- and
- a step of indicating the authenticity of the object on the basis of the result of at least one comparison.
A device for authenticating an object, characterised in that it comprises:
- a means for reading a 2D barcode to obtain a first message comprising a header identifying a resource of a certification and a signature produced by means of this resource;
- a means for calculating an element representative of the hash of the signature produced and/or of the signature produced;
- a means for reading a fragile anti-copy mark to obtain 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;
- a first means for comparing the representative element read with the representative element calculated;
- and
- a means for indicating the authenticity of the object on the basis of the result of at least one comparison.
