Differential Privacy

A mathematical framework for sharing aggregated data without exposing individual records. Used by ARIAA's federation layer.

ARIAA applies Laplace-mechanism differential privacy to federated signal sharing. The epsilon parameter is tunable per share; lower epsilon = more privacy, more noise. Every shared record carries its epsilon in metadata.
