Masters of Privacy

It is time to revisit Data Clean Rooms, having dedicated seven previous episodes to the topic across both the English and Spanish-language channels. The convergence of advanced data management techniques, more mature Privacy Enhancing Technologies, and sophisticated 1st-party data-based collaboration scenarios (on the back of AI, retail media, and Connected TV) already call for frequent updates. This is now accompanied by a more nuanced legal analysis that will benefit from the recent EDPS v. SRB (CJEU) case (on the relative nature of “personal data”).
Some common, burning questions that you will find answered in this episode: How do you apply Joint Controllership agreements to the various stages in common business cases? How to handle more complex relationships involving two or more parties?

On Wednesday November 19 2025, the European Commission unveiled its Digital Omnibus Package, which was basically split in two proposals: a proposed Regulation on simplification for AI rules; and a proposed Regulation on simplification of the digital legislation. We will tackle the first one today.
Today we are reviewing that AI-related block with Oliver Patel, who is AI Governance Lead at the global pharma and biotech company AstraZeneca, where he helps implement and scale AI governance worldwide. He also advises governments and international policymakers as a Member of the OECD’s Expert Group on AI Risk and Accountability.
