Online tracking: A 1-million-site measurement and analysis

Online tracking: A 1-million-site measurement and analysis is the largest
and most detailed measurement of online tracking to date. We measure
stateful (cookie-based) and stateless (fingerprinting-based) tracking, the
effect of browser privacy tools, and "cookie syncing".

This measurement is made possible by our web measurement tool OpenWPM, a
mature platform that enables fully automated web crawls using a
full-fledged and instrumented browser.

interested in tracking and privacy on the web
