Title:  Differentially Private Filtering



Emerging systems such as smart grids or intelligent transportation systems often require end-user applications to continuously send information to external data aggregators performing monitoring or control tasks. This can result in an undesirable loss of privacy for the users in exchange of the benefits provided by the application. Motivated by this trend, we introduce privacy concerns in a system theoretic context, and address the problem of releasing filtered signals that respect the privacy of the users' data streams. Our approach relies on a formal notion of privacy from the database literature, called differential privacy, which provides strong privacy guarantees against adversaries with arbitrary side information. This talk will discuss a number of scenarios where designing filters and dynamic estimators with privacy constraints is important, and show how tools from systems and control theory can help with this task.


Jerome Le Ny is an Assistant Professor in the Department of Electrical Engineering at Polytechnique Montreal since May 2012, and a member of GERAD, a multi-university research group on decision analysis. He was previously a Postdoctoral Researcher with the GRASP Laboratory and the PRECISE Center for embedded systems at the University of Pennsylvania. He graduated from the Ecole Polytechnique, France, in 2001, received an M.Sc. degree in Electrical Engineering from the University of Michigan, Ann Arbor, in 2003, and a Ph.D. degree in Aeronautics and Astronautics from the Massachusetts Institute of Technology, Cambridge, in 2008. His research interests include robust and stochastic control, scheduling and dynamic resource allocation problems, and security and privacy for cyber-physical systems, with applications to autonomous and embedded systems, multi-robot systems, and transportation systems.
