Abstract
In the era of big data, the traditional centralized data processing mode is not conducive to data security, data sharing, the reduction of data transaction cost and the full mining of data value. The unique data structure, distributed storage and consensus mechanism of blockchain technology have unique advantages in ensuring data security and sharing. However, the openness and distributed storage of Blockchain also make data privacy protection become a difficult problem. Specific to the financial field, the disclosure of financial data privacy will not only concern the privacy of users, the reputation of financial industry, but also concern China's financial security. Based on this, this paper takes Blockchain as the underlying technology of financial data application to discuss the privacy protection of financial data from the perspectives of technology and regulation. Finally, this paper constructs a financial data privacy protection framework of “Blockchain+privacy computing technology+regulation” in order to create a good dynamic environment for the security, sharing and privacy protection of financial data.
