Research on Data Ownership and Controllable Sharing Schemes in the Process of Logistics Data Flow

The secure and effective dissemination of logistics data is frequently obstructed by issues pertaining to ownership verification and unwanted access during data exchange. This study introduces an innovative strategy for data ownership verification and regulated sharing based on the notion of “three rights separation”, which delineates data ownership into control rights, usage rights, and management rights. The proposed approach incorporates chameleon signatures and blockchain technology to facilitate dynamic, non-falsifiable ownership marking and verification. Additionally, it utilizes searchable encryption and proxy re-encryption methods to guarantee that data are viewed solely under allowed circumstances, thereby averting misuse by third-party data administrators. Security analysis verifies resilience against adaptive chosen-message assaults and keyword-guessing threats, while simulation studies illustrate the scheme’s robustness, efficiency, and practical applicability in real-world logistical settings. This framework offers a scalable and safe solution for multi-party data sharing with explicitly defined ownership control.
