We examine a tradeoff between privacy and utility in terms of local differential privacy (L-DP) and Hamming distortion for certain classes of finite-alphabet sources under Hamming distortion. We define two classes: permutation-invariant, and ordered statistics (whose probability mass functions are monotonic). We obtain the optimal L-DP mechanism for(More)
To be considered for the 2016 IEEE Jack Keil Wolf ISIT Student Paper Award. We develop the tradeoff between privacy, quantified using local differential privacy (L-DP), and utility, quantified using Hamming distortion, for specific classes of universal memoryless finite-alphabet sources. In particular, for the class of permutation invariant sources (i.e.,(More)
