Privacy Leakage in Federated Learning: Gradient-Based Client Identity Inference and Defenses for Inertial Sensing in Vehicular Edge Networks
Research reveals that gradient updates in vehicular federated learning can expose client identities, undermining privacy claims of edge-AI architectures planned for 5G/6G connected mobility.

arXiv:2609.02971v1 Announce Type: new Abstract: As vehicular networks move toward 5G/6G edge intelligence, federated learning (FL) is widely promoted as a privacy-preserving way for vehicles and infrastructure to train shared models without exposing raw sensor data. Yet the updates clients transmit still leak enough information to identify who sent them, which threatens the anonymity that safety-critical V2X applications assume and adds to existing concerns over adversarial ML, model poisoning,
Editorial Analysis
Organisations deploying federated learning in connected-vehicle or IoT edge scenarios should reassess whether gradient sharing truly protects participant privacy.
