Duplicate coding internet of things traceability security label and 2-dimensional bar code security traceability method

Abstract

The invention discloses a duplicate coding internet of things traceability security label, comprising a 2-dimensional bar code, an upper layer label and a lower layer label. The 2-dimensional bar code comprises a 2-dimensional bar code external code and a 2-dimensional bar code internal code, wherein the 2-dimensional bar code external code is arranged on the upper layer label and used for goods traceablility querying; the 2-dimensional bar code internal code is arranged on the lower layer label and used for security verification; the upper layer label and the lower layer label only have edges jointed, and the upper layer label is provided with a tearing port; the 2-dimensional bar code internal code is used for a consumer to perform network security verification through handset scanning, the security verification being performed only once. After security verification, the security function of the 2-dimensional bar code internal code is immediately disabled, and scanning the 2-dimensional bar code internal code is equal to scanning a torn 2-dimensional bar code external code. The invention also discloses a 2-dimensional bar code security traceability method which is hard to copy and has high security.

Description

technical field [0001] The invention relates to a double-coded Internet of Things traceability anti-counterfeit label and a two-dimensional code anti-counterfeit traceability method. Background technique [0002] Two-dimensional barcode / two-dimensional barcode (2-dimensional barcode) records data symbol information with a specific geometric figure distributed on a plane (two-dimensional direction) according to certain rules; The concepts of "0" and "1" bit streams that constitute the internal logic basis of the computer use several geometric shapes corresponding to the binary to represent text and numerical information, and automatically read through image input equipment or photoelectric scanning equipment to realize automatic information processing. Processing: It has some common features of barcode technology: each code system has its specific character set; each character occupies a certain width; it has certain verification functions, etc. At the same time, it also has...

Problems solved by technology

Current anti-counterfeiting traceability technical solutions and defects: digital two-dimensional codes are directly printed with a series of anti-counterfeiting codes on the two-dimensional codes. When consumers scan and enter the anti-counterfeiting query page, they can directly input this series of anti-counterfeiting codes to check the authenticity

The disadvantage of this anti-counterfeiting technology is that it is easy to be copied, because most anti-counterfeiting companies currently have this technology, which is an open anti-counterfeiting technology
