ZKDP (Zero-Knowledge Differential Privacy Demo)

NOTE: This project wouldn't have been possible without the assistance of Ari Biswas, and was largely inspired by his paper: Interactive Proofs For Differentially Private Counting. This project was completed by groupmates Emily Kang, Max Wagner, Jaray Liu, Sol Kim, and Weiyuan Gong for COMPSCI208: Applied Privacy for Data Science under James Honaker and Salil Vadhan.

Overview

An interactive demo of verifiable differential privacy:

• Frontend: React app explaining zero-knowledge proofs, differential privacy, and sigma-OR protocols
• Backend: Rust API implementing verifiable DP with Pedersen commitments and cryptographic proofs
