This repository contains the code needed to reproduce the results in our NSDI '22 paper.
Components:
pql(Privid Query Language): parses Privid queries and computes the sensitivity needed to satisfy (p,K,e)-event-duration privacy given a privacy policy.analysis: code for reproducing plots in our paper.
Data:
- For Q1-Q3 and Q7-Q13, we collected video from 3 cameras (12 hours each) livestreamed to YouTube. We can provide the original source videos upon request. For now, we provide only the parsed data which we use in our analysis here.
- For Q4-Q6, we generated a synthetic dataset of appearances of taxis in front of 127 cameras over 1.5 years in Porto, Portugal, based on the ECML PKDD 2015 dataset challenge. Details can be found in
analysis/porto.
