Definition ∞ Federated learning security concerns the measures and protocols designed to protect data privacy and model integrity in distributed machine learning environments. This involves safeguarding individual user data from exposure during model training and preventing malicious actors from corrupting the global model. Techniques include differential privacy, secure aggregation, and cryptographic methods. Robust security is essential for trusted collaborative AI.
Context ∞ Federated learning security is a pressing research area, especially with increasing regulatory emphasis on data protection and the growth of privacy-preserving AI. The challenge involves balancing the utility of shared models with the stringent requirements for individual data confidentiality. Ongoing work seeks to develop more efficient and verifiable security primitives for these systems.
