A management method of commodity brand protection based on block chain

Abstract

The invention discloses a management method of commodity brand protection based on a block chain, comprising the following steps: the brand manufacturer digitally signs the commodity information PrdA,the manufacturer information MakerA and the next circulation link information PlaA with the private key held by the brand manufacturer, and uploads the digitally signed SignA and the public key PubAonto the block chain; Sales middlemen inspect the goods; whether the commodity information PrdA on the block chain is consistent with the actual commodity is used to prevent the counterfeit goods fromreplacing the original goods. The aim of the invention is to enable the brand manufacturer to crack down on counterfeit products from the source, brand protection has changed from passive to active,from post-counterfeiting to pre-counterfeiting, which can put an end to the circulation and sale of counterfeit commodities from the beginning, save the cost of brand manufacturers, and also greatly simplify and shorten the cost and time for purchasers and law enforcers to distinguish the true from the false.

Description

technical field [0001] The invention relates to the technical field of blockchain network applications, in particular to a management method for commodity brand protection based on blockchain. Background technique [0002] In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be tamper-proof and unforgeable distributed ledgers. [0003] Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing paradigm for programming and manipulating data through smart contracts composed of code. [0004] In layman's terms, the blockchain is a decentralized distributed ledger, which can also be understood as a da...

Problems solved by technology

[0009] However, this approach has a lot of loopholes and limitations

[0010] First of all, imitation manufacturers or vicious pirate manufacturers can print a large number of the same effective barcodes, or collude with the original manufacturer's internal staff to generate effective barcodes to deceive the security and anti-counterfeiting mechanism through barcode authentication, making it impossible for buyers to judge and identify authentic products.

[0011] Secondly, the user can only confirm the content of the barcode to the manufacturer of the product by phone or email when purchasing, but due to the size of the manufacturer or other reasons, it is impossible to respond to inquiries from buyers one by one.

Huge economic loss to both manufacturers and buyers

[0012] Although the third special anti-counterfeiting mark can increase the difficulty of selling pirated imitation products, it cannot completely eliminate the appearance of imitation products, especially the high price of world-class high-end products can fully cover the cost of anti-counterfeiting marks

[0015] Due to the loopholes and defects of the above-mentioned current anti-counterfeiting schemes and technologies, serious economic losses have been caused to consumers and brand manufacturers, and the orderly development of social economy has been affected.
