The Web Tracking Arms Race: Past, Present, and Future

Arvind Narayanan, Princeton University


The open web has led to a privacy and security arms race: the ad tech industry has come up with sneaky ways to track people’s activities online, but informed users can control ads and tracking using sophisticated client-side tools. The open web also allows researchers to study tracking on an unprecedented scale using automated browsers. In this talk, I’ll describe my research group’s findings on the state of online tracking, and our efforts to build tools to shift the balance in users’ favor. I’ll conclude with recommendations for policy makers and browser vendors. In particular, I’ll argue that there is no meaningful "neutral" stance on privacy; browser vendors who value user privacy should bundle technical defenses against tracking.
