Privacy-Preserving Federated Learning Across Heterogeneous Distributed Datasets: Quantum-Inspired Mechanisms, Explainable Classifiers and Multi-Domain Empirical Evidence
This paper addresses vulnerabilities in standard federated learning aggregation against gradient inversion attacks by evaluating three layered privacy-enhancing mechanisms: classical differential privacy (DP) noise injection, homomorphic encryption, and a novel quantum-inspired random unitary rotation of embedding vect...
