Design of anti-counterfeiting system based on blockchain and NFC tag

In order to solve the problems of centralized anti-counterfeiting system and illegal merchants copy authentic commodities at low cost and with low difficulty. This paper proposes an anti-counterfeiting system design based on the combination of blockchain and NFC tag. This system uses the Hyperledger Fabric blockchain development platform, Anti-counterfeiting certificates are used to prove that the commodities are genuine, encrypting the anti-counterfeiting certificate with ECC (Elliptic Curve Cryptography) public key forms ciphertext, then store the ciphertext in the blockchain ledger. Write the SHA256 value of the anti-counterfeiting certificate and the ECC private key, which can transform from ciphertext to anti-counterfeiting certificate, into the NFC tag. the query times can be recorded through MySQL database. It ensures the uniqueness and non replicability of the anti-counterfeiting certificate of the product, greatly improves the anti-counterfeiting performance and the difficulty of counterfeiting.
