Conclusion and Future Works

In this chapter, we first conclude this monograph and briefly summarize the data security challenges in future networks. Three blockchain-based data security approaches: Reliable data provenance, transparent data query, and fair data marketing are discussed, which not only realize a decentralized solution but address the efficiency, privacy, and fairness challenges with a blockchain architecture. Then, we investigate potential research directions, including on/off-chain computation models with modular designs, and multi-party fair AI model sharing with efficient verifications.
