Smart barcode with anti-counterfeiting function

Abstract

The invention relates to an intelligent bar code with an anti-counterfeit function. The intelligent bar code with the anti-counterfeit function is characterized in that the intelligent bar code comprises an isolating layer, an ink layer and a protective layer, the isolating layer, the ink layer and the protective layer are arranged on a base material from bottom to top in sequence, the ink layer is composed of ink and added materials, the added materials can be one or more of the inorganic salts such as Sn, Co, Al, As, Ir, Co, Te, Pb, W, Ta, Ca, Si, Pt, Sb, Ag, Fe, Na, Mg and Cu, the adding proportion of each added material is 0.5%-5%, and the adding proportion of all added materials is 0.5%-30%. According to the intelligent bar code with the anti-counterfeit function, different materials are added into the printing ink used when the bar code is manufactured, the material components in the ink layer are detected through a spectrograph, and the bar code meets requirements only under the condition that the material components coincide with bar code information. The spectra of materials corresponding to different kinds of bar code content are different, in order to counterfeit the bar code content, a counterfeiter needs to counterfeit the materials according to the bar code content, otherwise the inconsistency of bar codes can be judged through the spectrum, and thus the anti-counterfeit function is quite good.

Description

technical field [0001] The invention relates to an intelligent barcode, in particular to an intelligent barcode with anti-counterfeiting function. Background technique [0002] With food safety and other issues becoming more and more prominent, the existing anti-counterfeiting technology has been difficult to meet the product packaging, especially the anti-counterfeiting problem in the field of food safety. Now a low-cost, easy-to-manufacture, high-counterfeiting cost, and common detection methods are needed. Anti-counterfeiting method. [0003] Existing bar codes are generally simple anti-counterfeiting of printed information. The principle is: scan the bar code to form a corresponding number, and judge the check code in the number. The existing barcode generally has the following problems: (1) It is easy to be forged, as long as the generation method of the check code is cracked, it can be easily forged; (2) No relevant equipment is required in the process of barcode manu...

Problems solved by technology

The existing barcode generally has the following problems: (1) It is easy to be forged, as long as the generation method of the check code is cracked, it can be easily forged; (2) No relevant equipment is required in the process of barcode manufacturing, and no special production process

[0004] The barcode patent application for Raman spectroscopy with the application number CN201310089733.2 uses nano-particle materials, which are difficult to obtain; at the same time, because Raman spectroscopy is based on the structure of the molecular surface, the storage conditions of the barcode are relatively harsh and the surface is damaged. Such situations often cause the barcode anti-counterfeiting function to be invalid and inconvenient to use.
