Trends in Blockchain and Federated Learning for Data Sharing in Distributed Platforms
It surveys existing methods for improving data sharing in distributed networks, making it incremental as it summarizes trends without introducing novel solutions.
This paper reviews the integration of blockchain and federated learning to address security and privacy issues in data sharing for distributed platforms like IoT, 5G, and applications in industrial, vehicle, and healthcare sectors, but does not present new experimental results or concrete numbers.
With the development of communication technologies in 5G networks and the Internet of things (IoT), a massive amount of generated data can improve machine learning (ML) inference through data sharing. However, security and privacy concerns are major obstacles in distributed and wireless networks. In addition, IoT has a limitation on system resources depending on the purpose of services. In addition, a blockchain technology enables secure transactions among participants through consensus algorithms and encryption without a centralized coordinator. In this paper, we first review the federated leaning (FL) and blockchain mechanisms, and then, present a survey on the integration of blockchain and FL for data sharing in industrial, vehicle, and healthcare applications.
