DP-S4S: Accurate and Scalable Select-Join-Aggregate Query Processing with User-Level Differential Privacy
Yuan Qiu, Xiaokui Xiao, Yin Yang
Answering Select-Join-Aggregate queries with DP is a fundamental problem with important applications in various domains. The current SOTA methods ensure user-level DP (i.e., the ad…
Approximate DBSCAN under Differential Privacy
Yuan Qiu, Ke Yi
This paper revisits the DBSCAN problem under differential privacy (DP). Existing DP-DBSCAN algorithms aim at publishing the cluster labels of the input points. However, we show tha…
Differential Privacy on Dynamic Data
Yuan Qiu, Ke Yi
A fundamental problem in differential privacy is to release a privatized data structure over a dataset that can be used to answer a class of linear queries with small errors. This…
Frequency Estimation Under Multiparty Differential Privacy: One-shot and Streaming
Ziyue Huang, Yuan Qiu, Ke Yi +1
We study the fundamental problem of frequency estimation under both privacy and communication constraints, where the data is distributed among parties. We consider two applicat…
