Center node: "error bounds and guidelines for privacy calibration in differentially private kalman filtering"
  Abstract: Differential privacy has emerged as a formal framework for protecting sensitive information in networked systems. One key feature is that it is immune to post-processing, which means that arbitrary post-hoc computations can be performed on privatized data without weakening differential privacy. It is therefore common to filter private data streams. To characterize this setup, in this paper we present error and entropy bounds for Kalman filtering differentially private state trajectories generated by agents with linear dynamics. We consider input perturbation privacy, in which privacy guarantees are provided on an individual basis. We bound network-level a priori and a posteriori error and entropy of a Kalman filter processing agents' trajectories. Using the error bounds we develop, we further provide guidelines to calibrate individuals' privacy levels in order to keep filter error within pre-specified bounds. Simulation results are presented to demonstrate these developments.
