Abstract
In domains such as remote healthcare, where sensitive data must be protected, Federated Learning (FL) has emerged as a radical new way to build privacy-preserving AI models. In contrast, centralized AI systems have always existed, aggregating patient data into a single repository, subject to vulnerabilities in privacy, security, and regulatory compliance. In this study, we propose a novel FL implementation in remote healthcare that supports distributed training across multiple devices and remote healthcare facilities, while preserving patient privacy. We design a hypothetical framework taking advantage of the state of the art in machine learning tools including TensorFlow Federated and privacy enhancing technologies like differential privacy and secure aggregation. We evaluate the effectiveness of FL for simulating patient vitals, symptoms, and outcomes for different healthcare institutions in the research. This shows that FL can get comparable model accuracy with centralized systems, and its privacy and scalability aspect gains much more. Communication overhead and data heterogeneity are discussed, and practical strategies around their mitigation are laid out for the practical deployment of this method. In this work, we offer a comprehensive analysis of the application of FL in the healthcare domain, particularly on how it can contribute to the security of FL-sensitive data and the development of medical AI applications. Future research direction in building privacy-preserving AI models specific to the fluctuating needs of remote healthcare environments is now feasible with these results.
