Such signals must be adopted by both the sender (users) and\u00a0intended recipients (data processors). Adoption represents a coordination problem that remains unsolved despite efforts dating back to the 1990s. Browsers implemented\u00a0standards like the Platform for Privacy Preferences (P3P) and Do Not Track (DNT), but vendors profiting from personal data faced few incentives to receive and respect the\u00a0expressed wishes of data subjects. In the wake of recent privacy laws, a coalition of AdTech firms published the Transparency and Consent Framework (TCF), which defines\u00a0an opt-in consent signal. This talk integrates post-GDPR developments into the wider history of privacy preference signals. The story is illustrated with a number of web\u00a0measurements.\u00a0Biography:Daniel Woods is a Postdoctoral Fellow in the Department of Computer Science at the University of Innsbruck. His research\u00a0explores the incentive and information structures that determine how organisations make decisions about cybersecurity and\u00a0privacy. He received his PhD from the Department of Computer Science at the University of Oxford.
