Abstract:

We consider the problem of achieving pure differential privacy in the context of functional data analysis, or more general nonparametric statistics, where the summary of interest can naturally be viewed as an element of a function space. In this talk I will give a brief overview and motivation for differential privacy before delving into the challenges that arise in the sanitization of an infinite dimensional summary. I will present a new mechanism, called the Independent Component Laplace Process, for achieving privacy followed by several numerical examples.
