Problems solved by technology

[0003] Blockchain technology is a collection of computer information technology applications such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. From the perspective of data, the blockchain combines data blocks in a sequential manner in chronological order. A chained data structure, which is characterized by decentralization, openness and transparency, unalterability, and unforgeability. Blockchain technology has broad application prospects in product fidelity and traceability systems, although the application of blockchain technology can guarantee data Anti-counterfeiting and traceability in the circulation process, but there is still a key problem in applying blockchain technology to physical fidelity, anti-counterfeiting and traceability, that is, how to ensure that the physical object corresponding to the data has not been replaced or forged In kind, there is no existing technology that has a good solution for this

Embodiment Construction

[0066] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0067] first embodiment.

[0068] Such as Figure 1 to Figure 5 As shown, an article anti-counterfeiting and traceability method realized by using blockchain and its smart contract, the specific steps of the method at the production end 100 include:

[0069] Step S101: Deploy the smart contract, obtain the hash value returned by the blockchain 302: call the blockchain interface, publish a transaction 301 for deploying the smart contract to the blockchain, and obtain the hash value corresponding to the transaction 1 returned by the blockchain Hash value one 302;

[0070] Among them, for blockchain technology, the smart contract can be considered as a program running on the blockchain, so before deploying the smart contract, it is necessary to write the source program of the smart contract and c...

Abstract

The invention discloses an article anti-counterfeit and traceability method realized by using block chain and intelligent contract thereof. On the production side, the producer publishes the transaction of the deployment intelligent contract to the block chain, obtains the hash value returned by the block chain, attaches the hash value to the surface of the article, then photographs the image of the designated area on the surface of the article, then publishes the transaction of the deployment image to the block chain, obtains the hash value returned by the block chain, and passes the hash value to the intelligent contract; after the goods reach the consumer end through the circulation link, a consume obtains a hash value one from that surface of the article, then, the hash value 2 is obtained through block chain and intelligent contract, and image 1 is obtained, image 2 of the designated area on the surface of the article is taken, and image 1 and image 2 are identified and compared,and the consistency of the article is checked through the consistency identification and comparison of the images, so as to realize the anti-counterfeiting and traceability of the article.

Description

technical field [0001] The present invention relates to the fields of information processing technology and anti-counterfeiting technology, in particular to an article anti-counterfeiting and traceability method realized by using a block chain and its smart contract. Background technique [0002] In order to distinguish whether the items in circulation have been swapped, people use technologies such as QR codes and RFID. For some circulating items, there is another way to verify whether the item received by the receiver or consumer and the item sent by the sender or producer are the same item through the identification and comparison of the image of the item, which requires the receipt of the item The conditions for the sender of the item to take the image of the item are consistent with the conditions for the sender of the item to take the image of the item, and the sender of the item can transmit the image of the item taken by it to the receiver of the item through a chann...
