Artifact: xDup: Privacy-Preserving Deduplication for Humanitarian Organizations using Fuzzy PSI

This is the artifact accompanying our paper xDup: Privacy-Preserving Deduplication for Humanitarian Organizations using Fuzzy PSI published at the IEEE Symposium on Security and Privacy 2026. It contains the experimental results presented in the paper as well as the code and instructions to reproduce them.

This artifact is comprised of four largely independent components:
 
1. 🛡️ Our otFPSI prototype implementation and its evaluation
2. 🧩 Tooling to run Fmap-FPSI in your environment
3. 🗃️ The generation script for our synthetic dataset
4. 🔗 Implementation and evaluation of our embedding including baselines
