Differentially Private Communication of Measurement Anomalies in the Smart Grid

no code implementations4 Mar 2024 Nikhil Ravi, Anna Scaglione, Sean Peisert, Parth Pradhan

In this paper, we present a framework based on differential privacy (DP) for querying electric power measurements to detect system anomalies or bad data.

Differential Privacy for Class-based Data: A Practical Gaussian Mechanism

no code implementations8 Jun 2023 Raksha Ramakrishna, Anna Scaglione, Tong Wu, Nikhil Ravi, Sean Peisert

In this paper, we present a notion of differential privacy (DP) for data that comes from different classes.
