Abstract:

Data sharing and data distribution is the inevitable trend of social development. Meanwhile the security issues caused by data sharing also need to be concerned. Blockchain has the characteristics of traceability and non-tampering, which can effectively solve the single point of failure problem caused by the traditional data sharing and distribution scheme, and protect the data security at the same time. This paper proposed a data security sharing and controlled distribution model based on blockchain and cryptography, including data upload algorithm, data sharing algorithm and data distribution algorithm. IPFS is used to store data, and blockchain is used to record the whole process of data from upload to sharing and distribution, which traceable and fully ensures the security of data.

Key words: blockchain, data sharing, data distribution, IPFS
