Differential obliviousness (DO) is a privacy notion which guarantees that the access patterns
of a program satisfies differential privacy. Differential obliviousness was studied in a …

In the shuffle model for differential privacy, n users locally randomize their data and submit
the results to a trusted “shuffler” who mixes the results before sending them to a server for …

For anonymous communication networks (ACNs), Das et al. recently confirmed a long-
