NFC anti-counterfeiting chip, commodity anti-counterfeiting traceability method and device based on blockchain, and medium

Abstract

The invention discloses an NFC anti-counterfeiting chip, a commodity anti-counterfeiting tracing method and device based on the NFC anti-counterfeiting chip and a block chain, and a medium. The NFC anti-counterfeiting chip comprises a CPU, an NFC read-write interface unit, a chip identity information unit, a commodity identity information unit and a commodity query trace unit, and the NFC read-write interface unit is used for receiving data input of external NFC read-write equipment and encrypting the input data; the chip identity information unit is used for storing first chip identity information; the commodity identity information unit is used for storing first commodity identity information; and the commodity query trace unit is used for storing the first commodity query times. And theNFC anti-counterfeiting chip can be suitable for tracing the full life cycle of the commodity. The problem that in the prior art, a common anti-counterfeiting query label is prone to being copied, content is prone to being rewritten, and therefore commodity authenticity judgment is difficult to conduct through an identification label is solved.

Description

technical field [0001] The present application relates to the technical fields of NFC anti-counterfeiting chips and blockchains, and in particular to an NFC anti-counterfeiting chip and a product anti-counterfeiting traceability method, equipment, and medium based on the NFC anti-counterfeiting chip and blockchain. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is based on a decentralized peer-to-peer network, combining cryptography principles with consensus mechanisms, and using cryptography methods to generate associated data blocks. Each data block contains information about specific network transactions and is used to verify its The validity of the information and the generation of the next block realize the characteristics of instant verification, traceability and immutability of the information.
