- "To obtain private heavy hitters with central DP, a DP mechanism is applied for open set histograms. The idea is to add noise to the counts of strings in the aggregated histogram, then only keep the strings with counts above a certain threhold. The noise and threhold depends on (epsilon, delta)-DP budget, see [this doc](https://github.com/google/differential-privacy/blob/main/common_docs/.Delta_For_Thresholding.pdf) for detailed algorithm and proof. The noisy counts are rounded to integers as a post-processing step, which does not weaken the DP guarantee. Note that you will discover less heavy hitters when DP is required. This is because the thresholding step filters out strings with low counts. "
