Researchers are exploring advanced techniques to enhance privacy in Federated Learning (FL), a method where models train on decentralized data. One study compares Differential Privacy (DP) and Homomorphic Encryption (HE) for cardiovascular disease risk modeling using Swedish healthcare data, finding HE comparable to centralized methods but with higher computational overhead, while DP showed greater performance degradation for certain models. Another approach, FedPF, introduces a differentially private fair FL algorithm that balances fairness and utility by framing them as competing objectives, demonstrating significant discrimination reduction with competitive accuracy and a low computational footprint. A third paper combines DP with adaptive quantization to improve communication efficiency and privacy in non-IID FL settings, showing substantial data reduction on image datasets while maintaining accuracy and robust privacy.
