Product authentication and anti-counterfeiting method based on block chain technology

Abstract

The invention discloses a product authentication and anti-counterfeiting method based on a block chain technology. A block chain system capable of being authenticated publicly, a block chain gateway system, an intelligent mobile phone, an iPad or a similar tablet computer or another terminal with a photographing or / and NFC (IC) reading and writing function, an NFC anti-counterfeiting label with password protection, and an application APP operating in the intelligent mobile phone or the similar tablet computer are mainly used to store information generated in production and circulation links to the block chain, a pair of public key and private key is generated continuously, the traceability of each link can be ensured through repeatedly authenticating the private keys and the public keys, a password Pass is set for a cipher part according to the series number of the NFC, the public key B and the Hash value of the product, the problem that the whole label content is copied can be solved, and the anti-counterfeiting performance of a single product can be improved.

Description

technical field [0001] The invention relates to the technical field of product anti-counterfeiting, in particular to an anti-counterfeiting method for product authentication based on block chain technology. Background technique [0002] Existing anti-counterfeiting technologies mainly include the following types: [0003] Pure label type: including printing, watermark, laser anti-counterfeiting mark, metal thread, bubble anti-counterfeiting mark, NFC (IC) smart card, or DNA anti-counterfeiting mark and other physical marks; online technology: the corresponding authentication information is stored on the server on the Internet; Ordinary database storage; blockchain storage. [0004] The existing anti-counterfeiting technology mainly has the following defects: [0005] 1) Once it is physically copied, the anti-counterfeiting mark will become invalid immediately [0006] 2) No traceability, high link dependence, and it is difficult to prevent self-stealing (multiple opaque l...

AI Technical Summary

Problems solved by technology

[0005] 1) Once it is physically copied, the anti-counterfeiting mark will become invalid immediately

[0006] 2) No traceability, high link dependence, and it is difficult to prevent self-stealing (multiple opaque links and individuals need to be trusted)

[0007] 3) The existing anti-counterfeiting marks have no additional information or too little additional information

[0008] 4) The technology is difficult and the cost is high

[0009] 5) The certification threshold is high and requires expert certification

[0010] 6) The scope of application is narrow

But there is still a problem here. If the plagiarist completely copies all the readable content of the label, and the verification of the label is before the verification of the real product, then the fake will become the real product in the blockchain.
