Multidimensional anti-counterfeiting code label, its production method and identification method

Abstract

The invention provides a multidimensional anti-counterfeiting code as well as a manufacture method and a recognition method thereof. The multidimensional anti-counterfeiting code at least comprises an integrated three-layer structure, wherein the three-layer structure comprises a graphic code area, an external recognition code area and an internal verification code area; a graphic code is stored in the graphic code area and comprises n graph filling positions and m graphs which are randomly filled in the n graph filling positions; the permutation and combination of the graphic code area is m(n), wherein both n and m are integers, n is greater than m, n is greater than 5 and m is greater than 3; the external recognition code area is used for storing an external recognition code; after the external recognition code is scanned, commodity information and a comparison graphic code same as or similar to the graphic code stored in the graphic code area are matched; the internal verification code area is used for storing an internal identification code; and after the internal identification code is scanned, commodity management information is matched. The multidimensional anti-counterfeiting code can be effectively prevented from copy, is easy to fabricate and low in manufacture cost.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting technology, and in particular relates to a multi-dimensional anti-counterfeiting code label, its manufacturing method and identification method. Background technique [0002] With the continuous development of society and the continuous improvement of people's material living standards, scientific and technological products are used in all walks of life. In the field of anti-counterfeiting technology, the common anti-counterfeiting methods on the market are to use various digital anti-counterfeiting labels; Control printing or jet printing codes, and use various codes as anti-counterfeiting features. [0003] In the prior art, codes of pure digital information are usually used as anti-counterfeiting features. This kind of anti-counterfeiting technology is easy to identify, and is easy to be copied and copied for counterfeit goods; in order to solve the above problems, a new anti-counterfeiting c...

Problems solved by technology

[0003]In the prior art, the coding of pure digital information is usually used as the anti-counterfeiting feature. This kind of anti-counterfeiting technology is easy to identify, and it is easy to be copied and copied for counterfeit goods ; In order to solve the above problems, a new anti-counterfeiting code is designed. This kind of anti-counterfeiting code mainly adopts geometric shapes with specifications and colors, such as circles and triangles of various colors. During the printing process, due to its different color, a special color printing printer is required to produce anti-counterfeiting codes, and the production cost of color printing is high and time-consuming
