This article presents an optimization-based formulation for privacy-utility tradeoff in the ensemble and unscented Kalman filtering framework, focusing on the space situational awareness. Privacy and utility are defined in terms of lower and upper bound on the state estimation error covariance. The synthetic sensor noise is used to satisfy these bounds and is determined by solving an optimization problem. Given privacy and utility bounds, this article present optimization problem formulations…

On Detecting Deception in Space Situational Awareness
A machine-learning based anomaly detection tool which allows defenders to detect 90-98% of deception attempts with little to no in-house astrometry hardware is developed and evaluated.


Privacy-Aware Kalman Filtering
This work proposes to linearly transform the original observation into a lower dimensional space before sending them to fusion center to allow it to estimate the public state, while prevent it from estimating the private state.

A nonparametric optimization framework is proposed, which incorporates both inference and data privacy metrics, to design privacy mappings for the sensors without prior knowledge of the sensor observations' distribution, to allow the fusion center to accurately infer the public hypothesis while making it difficult to infer the private hypothesis and keeping the mutual information between each sensor and its private observation low.
Differential privacy for dynamical sensitive data
This work protects dynamical systems from being tracked by an adversary by providing differentially private guarantees by proposing a mechanism which adds artificial noise to the input of the system and the measurements which are then published.
Differential privacy in control and network systems
This tutorial paper gives a systems and control perspective on the topic of privacy preserving data analysis, with a particular emphasis on the processing of dynamic data as well as data exchanged in networks.
Inferential Privacy Guarantees for Differentially Private Mechanisms
The correlations and network structure amongst individuals in datasets today---whether explicitly articulated, or deduced from biological or behavioral connections---pose new issues around privacy
Differential Privacy and Qualitative Privacy Analysis for Nonlinear Dynamical Systems
Mechanism Design via Differential Privacy
It is shown that the recent notion of differential privacv, in addition to its own intrinsic virtue, can ensure that participants have limited effect on the outcome of the mechanism, and as a consequence have limited incentive to lie.
The Ensemble Kalman Filter: theoretical formulation and practical implementation
A fairly extensive discussion is devoted to the use of time correlated model errors and the estimation of model bias, and an ensemble based optimal interpolation scheme is presented as a cost-effective approach which may serve as an alternative to the EnKF in some applications.
The Algorithmic Foundations of Differential Privacy
The preponderance of this monograph is devoted to fundamental techniques for achieving differential privacy, and application of these techniques in creative combinations, using the query-release problem as an ongoing example.
New extension of the Kalman filter to nonlinear systems
It is argued that the ease of implementation and more accurate estimation features of the new filter recommend its use over the EKF in virtually all applications.
