Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] In the description of the present invention, it is intended to propose a way to register the identification code information of the commodity to the block chain, add the commodity to the Bloom filter for identification to replace the previous certificate system, and use the self-encoded Bloom filter to achieve A technical solution for preventing the illegal behavior of repeated use of the same two-dimensional code or barcode for the record of the inquire...

Abstract

The invention belongs to a block chain anti-counterfeiting technology, and particularly relates to an anti-counterfeiting identification method and device for preventing an identification code from being repeatedly used, and electronic equipment. The method comprises the following steps: generating identification code information for each qualified commodity by adopting a pseudo-random function, and sending the identification code of the commodity to a supervision node; after receiving the identification code information of the commodity, the supervision node sending the hash value processed by the endorsement node back to the manufacturer node from the channel; sending the endorsed identification code information to a sorting node for consensus, uploading after the consensus is completed, and storing the hash value of the identification code of the commodity; and after identification code information of the commodity is obtained through scanning, the chain code of the supervision node being called to inquire authenticity information of the commodity. According to the invention, the Bloom filter is arranged on the block chain, and the consensus algorithm is adopted, so that the repudiation behavior of merchant nodes can be prevented, and the accuracy of the traceability technology is improved.

Description

technical field [0001] The invention belongs to block chain anti-counterfeiting technology, and in particular relates to an anti-counterfeiting identification method, device and electronic equipment of an anti-reuse identification code. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, counterfeit and inferior commodities are increasing, causing great damage to the market economy and affecting the quality of national integrity. In order to solve this problem, anti-counterfeiting technology has received widespread attention. [0003] The traditional anti-counterfeiting technology is to use the anti-counterfeiting system to generate encrypted product information corresponding to the product one by one, and set a scanning code accumulation counter for each identification code information such as a two-dimensional code, and print or label the two-dimensional code on the product packaging ...
