Traceability enables the authenticity identification of a product and the monitoring of personnel mobility data. However, it is easy to find false data by query due to security issues during data storage. To ensure data authenticity and reliability, we propose a multi-party sharing system based on Blockchain for traceable data. The proposed architecture integrates the interplanetary file system and Blockchain storage to cope with a large amount of traceable data, which can significantly alleviate the pressure of data storage and impose another layer of protection on the chain. Using Blockchain and secure multi-party computation protocols can deal with the system’s illegal intrusion into others, horizontal penetration, and privacy leakage in terms of security issues.
