Object marking method and system and object recognition method and system based on two-dimensional codes

Abstract

The invention discloses an object marking method and system and an object recognition method and system based on two-dimensional codes. The marking method comprises the steps of S100 inputting characteristic information of objects to be marked; S200 generating characteristic two-dimensional codes by combining preset generation rules according to the characteristic information; and S300 marking thegenerated characteristic two-dimensional codes on the objects to be marked according to a one-to-one correspondence relation. In the invention, the characteristic information of the objects to be marked is obtained through a two-dimensional code generation device, then characteristic two-dimensional codes are generated on the basis of the characteristic information according to the preset generation rules, and the objects to be marked are marked by the generated two-dimensional codes according to a one-to-one correspondence relation. Therefore, repeated marking or missed marking can be avoided. Meanwhile, the characteristic two-dimensional codes can serve as unique identification codes of the objects because the marking is performed in a one-to-one correspondence manner so as to be used for differentiating the uniqueness and peculiarity of the objects.

Description

Technical field [0001] The invention relates to the field of anti-counterfeiting identification and two-dimensional codes, in particular to a two-dimensional code-based item identification method, identification method and system. Background technique [0002] Two-dimensional codes use specific geometric figures to record data symbol information in two-dimensional directions according to certain rules; use the concept of "0" and "1" bit streams that constitute the internal logic of the computer in code preparation, using several and The geometric shape corresponding to the binary system represents the numerical information of the text, which is automatically read by the image input device or the photoelectric scanning device to realize the automatic processing of the information: it has some common characteristics of the barcode technology: each code system has its specific character set; Each character occupies a certain width; has a certain check function, etc. Two-dimensional...

AI Technical Summary

Problems solved by technology

The disadvantage of anti-counterfeiting methods such as telephone code anti-counterfeiting and SMS anti-counterfeiting is that it is inconvenient to detect, that is, authentication and anti-counterfeiting need to be authenticated by telephone or SMS access every time the authenticity is detected

Radio frequency tags are used for anti-counterfeiting, the cost of anti-counterfeiting is high, and there are problems of environmental pollution

The existing two-dimensional code anti-counterfeiting technology, because of the low production cost of the two-dimensional code, leads to unscrupulous manufacturers to produce counterfeit products of high-quality products, or to sell expired or inferior products or second-hand products as original products, which greatly damages the consumer's reputation. interest, destroying social harmony and stability
