Data Circulation Blockchain Model Construction and Data Access Management

Abstract

This paper proposes a controllable Blockchain-based data circulation model. In this model, smart contracts stipulate that data circulation is carried out according to law, and laws and regulations to be followed in data circulation are written into system hardware and software. The supervision and execution of the law is automatically completed by the system. Through the risk assessment of the model, it can be seen that the data circulation Blockchain model has the characteristics of regionalization, security, credibility, collective maintenance, and non-tampering. It is suitable for solving the problem of data sharing and changing the circulation of data. The model promotes the in-depth integration of law and computer technology and promotes the process of legal automation.
