Data sharing systems must ensure that multiple participants can exchange data safely and efficiently.
However, traditional data sharing methods rely on centralized data storage, which leads to issues such as a single point of failure and availability problems
And concerns related to data ownership and data tampering.
Although these issues can be mitigated by blockchain technology, data privacy issues still remain.
As data sharing becomes more widespread, privacy issues become increasingly severe.
Privacy issues not only violate personal privacy but also discourage users from sharing data
And reducing participation in the system and ultimately degrading the quality of urban computing services.
Therefore, in this paper, we propose a blockchain-based data management system designed to enable secure data sharing.
