Abstract
The method for marking a product includes: a step of forming, on or in the product, a mark robust to copying, with a first resolution, a step of forming, on or in the product, a mark sensitive to copying, with a second resolution higher than the first resolution, a step of capturing an image of the robust mark, the sensitive mark and another part of the product and a step of memorizing an item of information representing the image of the robust mark, the sensitive mark and the other image part. In embodiments, during at least one forming step, the position of the mark formed during this forming step is random in relation to the other image part.
Claims16
A method for marking a product, the method comprising:
- forming, on or in said product, a mark robust to copying, with a first resolution;
- forming, on or in said product, a mark sensitive to copying, with a second resolution higher than the first resolution;
- capturing an image of said mark robust to copying, said sensitive mark and another part of the product;
- and
- memorizing an item of information representing the image of said mark robust to copying, said sensitive mark and said other part of the product.
A device for marking a product, the device comprising:
- a means of forming, on or in said product, a mark robust to copying, with a first resolution;
- a means of forming, on or in said product, a mark sensitive to copying, with a second resolution higher than the first resolution;
- an image sensor designed to capture an image of said mark robust to copying, said sensitive mark and another part of the product;
- and
- a means of memorizing an item of information representing the image of said mark robust to copying, said sensitive mark and said other part of the product.
A method for authenticating a product, the method comprising:
- capturing, on said product, an image of a robust mark and a mark sensitive to copying with a higher resolution than the mark robust to copying, and another part of the product;
- transmitting an item of information representing the image of said robust mark, said sensitive mark and said other part of the product;
- comparing said item of information representing the image of said mark robust to copying, said sensitive mark and said other part of the product with at least one remote memorized item of information;
- and
- depending on the result of said comparison step, displaying data relating to the product, an image of which was captured.
A device for authenticating a product, the device comprising:
- a means of capturing, on said product, an image of a mark robust to copying and a mark sensitive to copying with a higher resolution than the mark robust to copying, and another part of the product;
- a means of transmitting an item of information representing the image of said mark robust to copying, said sensitive mark and said other part of the product;
- a means of comparing said item of information representing the image of said mark robust to copying, said sensitive mark and said other part of the product with at least one remote memorized item of information;
- and
- a means of displaying data relating to the product, an image of which was captured, depending on the result provided by the comparison means.
