Title
Preserving Privacy and Fidelity via Ehrhart Theory
Abstract
We consider the problem of designing a database sanitization mechanism (DSM) that minimizes, in the expected sense, the L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> -distortion between the histograms of original and sanitized databases, while being θ-differentially private (DP). The expected L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> -distortion of a corresponding optimal θ-DP DSM provides for an important utility-privacy trade-off. This problem reduces to a prohibitively complex linear program (LP). Using tools from Ehrhart theory, analytic combinatorics and LP theory, we solve this problem and thereby provide a simple closed form computable expression characterizing this trade-off.
