Cookies and Tracking Technologies: Risks, Challenges, and Future Outlook (Presentation Slides) Article Swipe
This presentation was given as a keynote at the BNP Paribas World Data Protection Week 2021. Starting with the composition of an advertisement, I unravel the intricacies of the online advertising ecosystem (Real-Time Bidding). The graph-based methodological approach enables the differentiation of advertising systems. The methodology also enables the differentiation of cookie compliance in European countries by visiting websites without giving consent for tracking. There are three post-Do Not Track observations worth noting: (1) Federated Learning of Cohorts (FLoC), (2) IDFA and the AppTrackingTransparency framework, and (3) Global Privacy Control (GPC). Furthermore, I discuss five post-Do Not Track browser improvements: (1) Client-Side Storage Partitioning, (2) First-Party Sets, (3) IsLoggedIn API, (4) Private Click Measurement, and (5) Storage Access API. The observations and browser improvements lead to a discussion on cookie banners in which the number of clicks to consent or object are presented as a metric. I close the presentation with remarks on the EU Council's presidency by Portugal; The Portuguese Presidency is leading the ePrivacy Regulation discussion in the Working Party on Telecommunications and Information Society of the Council of the European Union.
