Problems solved by technology

[0002] Product verification devices known in the prior art are reserved for professionals equipped with expensive special equipment
So consumers cannot verify the authenticity of the product before purchasing (e.g., in a mall) or consumption (e.g., in a restaurant)
Therefore, the counterfeiting of expensive products, especially alcohol, medicines and perfumes etc. is easy to expand

Embodiment Construction

[0049] Before describing in detail various specific embodiments of the present invention, some definitions to be used in the description are explained as follows:

[0050] - "Information Matrix": A physical representation of a message, readable by a machine, usually attached to a solid surface (unlike watermarks or digital watermarks, which modify the pixel values ​​of the design to be printed). Definitions of information matrices include, for example, 2D barcodes, 1D barcodes and other less invasive ways of representing information such as "Dataglyphs".

[0051] - "marking" or "printing": any method of converting a digital image (preferably, including an information matrix) into its representation in the real world, which representation is usually formed on a surface: by exclusive means, including: inkjet Printing, laser printing, lithographic and thermal printing as well as embossing, laser engraving and hologram generation. Also included are more complex methods such as mo...

Abstract

he 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.

Description

technical field [0001] The present invention relates to a method and apparatus for marking a product and a method and apparatus for authenticating a product by a consumer. The invention is applicable to all kinds of products, with or without packaging. Background technique [0002] The product verification devices known in the prior art are reserved for professionals equipped with expensive special equipment. So consumers have no way to verify the authenticity of the product before buying (eg, in a mall) or before consuming it (eg, in a restaurant). Therefore, the counterfeiting of expensive products, especially alcohol, medicines and perfumes etc. is easy to expand. Contents of the invention [0003] The aim of the present invention is to remedy all or some of these drawbacks. [0004] To this end, according to a first aspect, the invention envisages a method for marking a product comprising: [0005] - with a first resolution, the step of forming a replication-stable...
