“You trust your chatbot with everything. Should you?” is the title of Theodore Christakis’ comprehensive research project on the privacy of our conversations with AI. Part two of this project (“Governments, Courts and the Battle Over Your Chatbot Conversations”) was published on June 8th, and we have taken the opportunity to ask the author for a high-level overview of his findings. On top of this, we have also discussed his separate piece on the rise of AI-powered health assistants against the backdrop of the new European Health Data Space, discussed last week in our Spanish-language channel.
(Our previous conversation with Mr. Christakis focused on the use of personal data in LLM training datasets.)
Theodore Christakis is Professor of International, European and Digital Law at University Grenoble Alpes (France). He holds, since 2019, the Chair on the Legal and Regulatory Implications of Artificial Intelligence at the Multidisciplinary Institute on AI (AI-Regulation.com). He is Director of Research for Europe at the Cross-Border Data Forum, a member of the Board of Directors of the Future of Privacy Forum, and a former Distinguished Visiting Fellow at the New York University Cybersecurity Centre.
His work focuses on the questions at the centre of today’s debates on digital sovereignty: government access to data held by private companies, international data transfers, the security and operational resilience of digital infrastructure, and the regulation of artificial intelligence. He served as an expert for the OECD in the process that led to the adoption, in December 2022, of the OECD Declaration on Government Access to Personal Data Held by Private Sector Entities. He was a member of the International Data Transfers Experts Council of the United Kingdom Government, and an expert for the High-Level Expert Group on Access to Data for Effective Law Enforcement established by the European Commission and the Council of the European Union. He has also served as a member of the French National Digital Council and of the French National Committee on Digital Ethics.
He has published or co-edited twelve books and is the author or co-author of more than 120 academic articles and book chapters. He has been invited to lecture and present his work at conferences, workshops and seminars on more than two hundred occasions, in over 38 countries.
As an independent expert, he advises governments, international organisations and private companies on questions of international and European law, cybersecurity, artificial intelligence, digital sovereignty and data protection.
