Center node: "an estimation theoretic view of privacy"
  Abstract: We study the central problem in data privacy: how to share data with an analyst while providing both privacy and utility guarantees to the user that owns the data. We present an estimation-theoretic analysis of the privacy-utility trade-off (PUT) in this setting. Here, an analyst is allowed to reconstruct (in a mean-squared error sense) certain functions of the data (utility), while other private functions should not be reconstructed with distortion below a certain threshold (privacy). We demonstrate how a $\chi^2$-based information measure captures the fundamental PUT, and characterize several properties of this function. In particular, we give a sharp bound for the PUT. We then propose a convex program to compute privacy-assuring mappings when the functions to be disclosed and hidden are known a priori. Finally, we evaluate the robustness of our approach to finite samples.
