Describes a practical DCGAN model inversion that reconstructs MRI training images from federated-model weights, measures cosine-similarity (many reconstructions 70–80% similar), and shows differential privacy reduces reconstruction quality at the cost of roughly 20% accuracy on complex image tasks. Surveys frameworks (TFF, FATE, IBM FL, OpenFL), evaluates aggregation algorithms, and demonstrates a fog node for IoT that lets resource-constrained devices join federated intrusion‑detection training with >90% system accuracy and only 1–5% drop when DP is applied.
