Bayesian synthesis, which generates synthetic data by sampling from the posterior predictive distribution, is a popular approach for privatizing sensitive personal data. However, how attribute disclosure risk is affected by feature dimensionality, the number of individuals in the original dataset, and the amount of rel...

In particular, it remains unclear how much an adversary's belief about an individual's inclusion in a dataset can change after observing a protect...
