Privacy-Aware Kalman Filtering

Yang Song, Chong Xiao Wang, Wee Peng Tay

We are concerned with a privacy-preserving problem in Kalman filter: a sensor releases a set of measurements to fusion center, who has perfect knowledge of the dynamical model, to allow it to estimate the public state, while prevent it from estimating the private state. We propose to linearly transf…
