Differential Privacy Analysis of Decentralized Gossip Averaging under Varying Threat Models

arXiv — cs.LGWednesday, December 3, 2025 at 5:00:00 AM
  • A novel privacy analysis of decentralized gossip-based averaging algorithms has been introduced, focusing on achieving differential privacy guarantees in decentralized machine learning settings. This analysis addresses challenges posed by the lack of a central aggregator and varying trust levels among nodes, utilizing a linear systems framework to characterize privacy leakage across different scenarios.
  • This development is significant as it enhances the scalability and robustness of machine learning models while ensuring privacy, which is crucial in an era where data protection and user trust are paramount. The findings could lead to more secure decentralized learning systems that are resilient against potential privacy breaches.
  • The research aligns with ongoing efforts to improve machine learning frameworks, particularly in decentralized environments. It reflects a growing recognition of the need for robust privacy measures in AI, especially as federated learning and decentralized approaches gain traction. The interplay between privacy, model robustness, and the dynamics of client behavior in decentralized systems continues to be a critical area of exploration.
