Online tracking: A 1-million-site measurement and analysis
Coauthor here. I lead the research team at Princeton working to uncover online tracking. Happy to answer questions.<p>The tool we built to do this research is open-source <a href="https://github.com/citp/OpenWPM/" rel="nofollow">https://github.com/citp/OpenWPM/</a> We'd love to work with outside developers to improve it and do new things with it. We've also released the raw data from our study.
