Two-dimensional code based block chain logistics source-tracing tracking and anti-counterfeiting method

Abstract

The invention discloses a two-dimensional code based block chain logistics source-tracing tracking and anti-counterfeiting method. The method takes a source-tracing tracking and anti-counterfeiting system as a basis. The source-tracing tracking and anti-counterfeiting system comprises a block chain background system capable of being publicly authenticated, a block chain gateway system, a mobile intelligent reading and writing terminal, a cache database and two-dimensional code anti-counterfeiting label. The method comprises the steps of (1) generating a two-dimensional code anti-counterfeiting label; (2) initializing the anti-counterfeiting label; (3) activating by a manufacturer; (4) adding information by an intermediate merchant; and finally (5) performing verification by a user, wherein the two-dimensional code becomes invalid after the user verifies the authenticity. The method disclosed by the invention can solve problems of trust dependence of the user for each node, trust dependence of the user for a third-party, dependence of the user for technologies, trust dependence of the user for an anti-counterfeiting identifier and trust object dislocation in each link of product logistics, is low in entry threshold and can greatly improve the anti-counterfeiting safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of blockchain traceability, and in particular relates to a two-dimensional code-based blockchain logistics traceability and anti-counterfeiting method. Background technique [0002] The existing traceability and tracking technologies mainly include the following types: (1) RFID wireless radio frequency technology, that is, to add a logo with a chip on the product packaging, and the information of the product in the business process can be recorded and read from the chip. Get complete information; (2) QR code, that is, the product is identified by the QR code, the QR code is associated with the relevant information of the product, and also records the relevant information: (3) Bar code, add the basic information of the product to the bar code Information, including the date of creation, production time, batch number and other information. Existing existing anti-counterfeiting technologies mainly include the ...

AI Technical Summary

Problems solved by technology

[0003] (1) Once it is physically copied, the anti-counterfeiting mark will become invalid immediately, and copying is only a matter of time and cost;

[0004] (2) No traceability, high link dependence, it is difficult to prevent self-stealing (need to trust multiple opaque links and individuals), for example, we need to trust retailers, shippers, express companies, etc. when we buy a Kun bag, and we often do not know the need Who are these links and people of trust;

[0005] (3) The existing anti-counterfeiting mark has no additional information or too little additional information;

[0006] (4) The technology is difficult and the cost is high. Only a small number of manufacturers can produce physical labels including metal wires and DNA anti-counterfeiting labels, and the production cost is high;

[0007] (5) The certification threshold is high and requires expert certification. Many anti-counterfeiting labels are difficult to fake, such as DNA anti-counterfeiting labels. Ordinary individuals cannot judge the authenticity. For example, in order to identify DNA anti-counterfeiting labels, professional certification personnel must be invited for certification
