We consider the problem of designing a database sanitization mechanism (DSM) that minimizes, in the expected sense, the L

-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. |
