Advancing Privacy and Fairness in Healthcare Using Federated Edge Learning and Blockchain
Bibliographic record
Abstract
Artificial intelligence (AI) has revolutionized many fields, including healthcare. The adoption of AI techniques in critical healthcare tasks, such as cancer diagnosis, holds great promise for revolutionizing the healthcare system. AI algorithms can be trained on vast datasets to recognize patterns, detect anomalies, and provide accurate assessments. However, the lack of realistic and up-to-date medical data poses a significant challenge to the widespread adoption of AI techniques. Additionally, privacy concerns surrounding sensitive medical data, particularly Patient Health Records (PHR), hinder data sharing among healthcare practitioners. This paper aims to address these challenges by proposing a novel framework, entitled SecureMed, that uses Federated Learning (FL) and Blockchain to preserve privacy in the healthcare system. In particular, SecureMed consists of (1) A novel distributed architecture that enables secure collaboration among multiple Mobile Edge Computing (MEC)-based Internet of Medical Things (IoMT) devices, while ensuring the privacy of healthcare systems; (2) A fairness-aware Federated Learning (FL) solution to ensure that model performance is balanced across all participating healthcare institutions, addressing the issue of imbalanced data contributions; (3) A Secure Multiparty Computation (SMPC) protocol to ensure secure aggregation of local model updates; and (4) A blockchain-based reputation model for collaborative FL training. The proposed framework leverages smart contracts to ensure trustworthiness, decentralization, and transparency in the FL process. The experimental results using the CIC IoMT dataset 2024 highlight the promising potential of SecureMed in revolutionizing healthcare systems.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
