Commodity anti-counterfeiting traceability method based on block chain technology

Abstract

The invention discloses a commodity anti-counterfeiting traceability method based on a block chain technology. The method at least comprises the following steps of information acquisition, informationmarking, authentication ID generation, data storage, access instruction receiving and access frequency comparison. According to the method, commodity anti-counterfeiting traceability is innovativelycompleted through a block chain technology, so that a user using the method can store the content of data in situ, and hash values in one-to-one correspondence with the data, identity identification information of the user and basic attribute data of target file data are associated and stored in a trusted block chain; therefore, the original creation and attribution of the data can be proved whilethe data leakage is avoided, and meanwhile, the corresponding certificate storage certificate is generated, and therefore a way for proving and verifying the certificate is provided for other people.More importantly, decentralization is realized by using a block chain technology, so that the data is real, credible and tamper-resistant, the commercial privacy data protection is protected, and theauthority and credibility of the platform and the enterprise participation enthusiasm are guaranteed.

Description

Technical field[0001]The invention relates to the technical field of product anti-counterfeiting traceability, in particular to a commodity anti-counterfeiting traceability method based on blockchain technology.Background technique[0002]When consumers buy commodities, especially medicines, foods and some imported commodities, they often worry about the authenticity and distribution channels of the commodities, so they hope to provide a convenient and effective way to monitor the whole process of commodities. For commodity manufacturers, it is also necessary to prevent criminals from counterfeiting the commodities produced by the enterprise. Therefore, it has become an urgent need for modern society to provide a standard and unified method for anti-counterfeiting and traceability of commodities.[0003]For example, the current implementation of anti-counterfeiting traceability of drugs is assured on the code. The specific process is roughly as follows:[0004]1. Drug manufacturers can go...

Problems solved by technology

[0009] However, this method adopts a centralized structure, so that all data is stored on the safe platform, resulting in the inability to effectively protect some commercially confidential data of commodity manufacturers and distribution companies, and related companies cannot effectively cooperate; and the centralized method is very easy be attacked or compromised, reducing the stability of the method

The most important thing is that the authenticity and authority of the data in this method cannot be guaranteed, and data tampering and counterfeiting cannot be prevented, which greatly reduces the security of the method and is not conducive to the use of existing products.
