Research on data security sharing mechanism and application based on blockchain and privacy computing

The rapid growth and massive accumulation of various types of data have driven all walks of life to achieve high-quality development, and have had a major and profound impact on social governance and people’s lives. However, there are many problems in the traditional data transaction and sharing, such as the loss of data ownership and the leakage of original data information. How to ensure the invisibility of data and the determination of data ownership while sharing data is an urgent problem. Based on this, combining the advantages of emerging technologies such as blockchain and privacy computing, this paper proposes a data security sharing architecture and mechanism based on blockchain and privacy computing to ensure the effective protection of personal information in the process of data sharing, to realize the safe circulation and sharing of data.
