Abstract

The invention discloses a commodity anti-counterfeiting traceability method and system based on a blockchain and an NFC chip, and relates to the field of information encryption storage. The method comprises: encrypting header information of a blockchain data block through an encryption algorithm, and generating a public key; storing a public key generated by encryption in the NFC chip; reading a public key stored in the NFC chip when writing or querying the blockchain data; and decrypting the header information of the blockchain data block by using the read public key, so as to write the commodity information in the blockchain or query the commodity information written before. Through the interaction mode of combining the blockchain and the NFC chip, the safety of data information is ensured while the convenience of data is ensured.

Description

technical field [0001] The invention relates to the field of information encryption storage, in particular to a method and system for anti-counterfeiting and traceability of commodities based on block chains and NFC chips. 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 (Blockchain) is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks associated with cryptographic methods. Each The data block contains a batch of bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block. [0003] As a new technology concept that has emerged in recent years, blockchain technology has many inherent advantages, such as decentraliz...
