Differential Privacy (DP) has gained growing attention given its mathematically rigorous guarantee to prevent the worst case scenario of privacy leak. However, new procedures are needed to analyze DP synthetic datasets when Rubin's combining rules for multiple imputation based synthetic data sets are not valid. In this talk, we consider the multivariate regression setting and discuss how to correct for biases induced by introducing the DP mechanism, and provide a proper accounting of uncertainty. Using real datasets, we show how we can obtain approximately the same inference results while still satisfying DP criterion for privacy protection.
