Summary Reports Optimization in the Privacy Sandbox Attribution Reporting API

Hidayet Aksu, Badih Ghazi, Pritish Kamath +4

The Privacy Sandbox Attribution Reporting API has been recently deployed by Google Chrome to support the basic advertising functionality of attribution reporting (aka conversion me…

Differentially Private Heatmaps

Badih Ghazi, Junfeng He, Kai Kohlhoff +4

We consider the task of producing heatmaps from users' aggregated data while protecting their privacy. We give a differentially private (DP) algorithm for this task and demonstrate…

Private Counting of Distinct and k-Occurring Items in Time Windows

Badih Ghazi, Ravi Kumar, Pasin Manurangsi +1

In this work, we study the task of estimating the numbers of distinct and -occurring items in a time window under the constraint of differential privacy (DP). We consider severa…

Anonymized Histograms in Intermediate Privacy Models

Badih Ghazi, Pritish Kamath, Ravi Kumar +1

We study the problem of privately computing the anonymized histogram (a.k.a. unattributed histogram), which is defined as the histogram without item labels. Previous works have pro…

Private Isotonic Regression

Badih Ghazi, Pritish Kamath, Ravi Kumar +1

In this paper, we consider the problem of differentially private (DP) algorithms for isotonic regression. For the most general problem of isotonic regression over a partially order…

Algorithms with More Granular Differential Privacy Guarantees

Badih Ghazi, Ravi Kumar, Pasin Manurangsi +1

Differential privacy is often applied with a privacy parameter that is larger than the theory suggests is ideal; various informal justifications for tolerating large privacy parame…
