Have your data and hide it too: An introduction to differential privacy

This project involved developing a differentially private version of DAP (Data Aggregation Protocol) which is a protocol designed by Cloudflare. The new version uses cryptographic techniques to protect sensitive information while still allowing aggregated data to be analyzed. It was implemented in the Rust programming language, and various differential privacy mechanisms were explored before finally settling on discrete Gaussian and discrete Laplace mechanisms. By adapting the Daphne implementation of DAP, a toy deployment of DAP with differential privacy was successfully run on network error logging data.
