Problems solved by technology

However, it is necessary to resort to a laboratory for analysis and detection of counterfeit products; this process is too time-consuming and laborious
[0004] It is not economically viable for a solution that includes analytical equipment dedicated to the development of each product

Embodiment Construction

[0048] exist figure 1 In the case of the analyses, light waves are analyzed which are transmitted through a substance containing the combination of markers, more precisely to a sample which may be diluted in solution.

[0049] It should be noted that this analysis can also be done on objects whose material allows it, or on matter directly through its receptors.

[0050] In this example, the identification and verification equipment using the method of the present invention comprises a spectrophotometer comprising:

[0051] - an emitter of optical radiation with a long spectrum, the intensity of which can be adjusted using a light source 4 powered by a power-adjustable current generator 6; a collimator 2, on whose axis a lens 5 is placed,

[0052] - a product sample 8 contained in a transparent receiver 9, positioned on the optical axis of the emitter,

[0053] - a dispersing element 1, located on said optical axis on the side opposite the emitter of the receiver 9; this disp...

Abstract

The invention relates to a method for authenticating different objects or substances to be identified, which method consists of at least two stages: during an initial stage, a plurality of chemical markers are selected, a combination of markers is assigned to and implanted in each object or substance, establish an identification code and / or verification code (block 2, 11), store in memory the data or code used to identify and / or verify all objects or substances and additional data; during an identification and verification phase, A spectrometric analysis is performed to determine a specific scan code that detects the presence or absence of the mark (blocks 3, 4) and identifies the object or substance by comparing the scan code with an identification code and / or a verification code (block 6 ). The present invention can be specifically applied to counterfeiting, automatic classification, etc.

Description

technical field [0001] The present invention relates to a method for authenticating objects or substances using chemical markers or tracers. More specifically, but not exclusively, it has applications in counterfeiting, automatic classification, etc. Background technique [0002] As a general rule, numerous objects or substances in transit or for sale are identified by barcodes. By means of this barcode it is possible to identify the products, but not sufficient to authenticate them, ie not to prove after analysis that the object or substance is indeed the product identified by the barcode. [0003] In attempting to solve this problem, various methods of integrating chemical labels into objects or substances have been developed. However, it is necessary to turn to a laboratory to analyze and detect counterfeit products; this process is too time-consuming and laborious. [0004] As for a solution involving the development of dedicated analytical equipment for each product,...
