Bridging Differential Privacy and Random Triangles
Tianxi Ji
The classical analysis of the Gaussian mechanism in differential privacy reduces privacy loss for a pair of neighboring datasets to a scalar random variable. While this scalar char…
Less is More: Revisiting the Gaussian Mechanism for Differential Privacy
Tianxi Ji, Pan Li
Differential privacy via output perturbation has been a de facto standard for releasing query or computation results on sensitive data. However, we identify that all existing Gauss…
PROVGEN: A Privacy-Preserving Approach for Outcome Validation in Genomic Research
Yuzhou Jiang, Tianxi Ji, Erman Ayday
As genomic research has grown increasingly popular in recent years, dataset sharing has remained limited due to privacy concerns. This limitation hinders the reproducibility and va…
DP-PSI: Private and Secure Set Intersection
Jian Du, Tianxi Ji, Jamie Cui +3
One way to classify private set intersection (PSI) for secure 2-party computation is whether the intersection is (a) revealed to both parties or (b) hidden from both parties while…
Robust Fingerprinting of Genomic Databases
Tianxi Ji, Erman Ayday, Emre Yilmaz +1
Database fingerprinting has been widely used to discourage unauthorized redistribution of data by providing means to identify the source of data leakages. However, there is no fing…
Energy-Efficient Computation Offloading in MobileEdge Computing Systems with Uncertainties
Tianxi Ji, Changqing Luo, Lixing Yu +4
Computation offloading is indispensable for mobile edge computing (MEC). It uses edge resources to enable intensive computations and save energy for resource-constrained devices. E…
Privacy-Preserving Database Fingerprinting
Tianxi Ji, Erman Ayday, Emre Yilmaz +1
When sharing sensitive relational databases with other parties, a database owner aims to (i) have privacy guarantees for the database entries, (ii) have liability guarantees (via f…
The Curse of Correlations for Robust Fingerprinting of Relational Databases
Tianxi Ji, Emre Yilmaz, Erman Ayday +1
Database fingerprinting have been widely adopted to prevent unauthorized sharing of data and identify the source of data leakages. Although existing schemes are robust against comm…
Genomic Data Sharing under Dependent Local Differential Privacy
Emre Yilmaz, Tianxi Ji, Erman Ayday +1
Privacy-preserving genomic data sharing is prominent to increase the pace of genomic research, and hence to pave the way towards personalized genomic medicine. In this paper, we in…
