Increasing use of ML technologies in privacy-sensitive domains such as medical diagnoses, lifestyle predictions, and business decisions highlights the need to better understand if…
Answering Multi-Dimensional Range Queries under Local Differential Privacy
Jianyu Yang, Tianhao Wang, Ninghui Li +2
In this paper, we tackle the problem of answering multi-dimensional range queries under local differential privacy. There are three key technical challenges: capturing the correlat…
PolyScope: Multi-Policy Access Control Analysis to Triage Android Systems
Yu-Tsung Lee, William Enck, Haining Chen +6
Android filesystem access control provides a foundation for Android system integrity. Android utilizes a combination of mandatory (e.g., SEAndroid) and discretionary (e.g., UNIX pe…
Continuous Release of Data Streams under both Centralized and Local Differential Privacy
Tianhao Wang, Joann Qiongna Chen, Zhikun Zhang +5
In this paper, we study the problem of publishing a stream of real-valued data satisfying differential privacy (DP). One major challenge is that the maximal possible value can be q…
Towards Effective Differential Privacy Communication for Users' Data Sharing Decision and Comprehension
Aiping Xiong, Tianhao Wang, Ninghui Li +1
Differential privacy protects an individual's privacy by perturbing data on an aggregated level (DP) or individual level (LDP). We report four online human-subject experiments inve…
