Program Summary
Tuesday 31 March, two guest lecturers from the EU will share their practical experiences with privacy negotiations with Big Tech, the impact of the EU Digital Services Act and the planned reform of the General Data Protection Regulation (GDPR).
Professor dr. Frederik Zuiderveen Borgesius from Radboud University in the Netherlands will explain why many US Big Tech companies are so upset about the EU Digital Services Act, and why a possible limitation of the definition of personal data in the GDPR will undermine fundamental rights protection.
Drs Sjoera Nas is a privacy consultant for the Dutch government and the Dutch education sector, and will explain how she uses Data Protection Impact Assessments to improve GDPR-compliance of Big Tech. They will both address the problematic diplomatic relationship with the USA, and what the Netherlands and the EU are doing to enhance data sovereignty.
Two professors of the University of Tokyo will also give their view on policy, legal and jurisprudential developments in Japan regarding privacy, data protection and the use of USA Big Tech services.
Professor Noboru Koshizuka will speak about technologies that enable both data utilization and the protection of personal data, including Data Spaces, AI, and Privacy-Enhancing Technologies (PETs). These technologies can play an important role in supporting the enforcement of data protection and privacy frameworks. At the same time, no technology is perfect, and each has its own limitations and trade-offs. His talk will explore both the potential and the challenges of these technologies, and consider how they may contribute to enhancing data sovereignty in practice.
Professor Itsuko Yamaguchi will speak about “Co-creation of ‘International Information Law’: Unleashing Dragons toward Global Privacy Protection amid AI-led Innovation and Democratic Backsliding.” In so doing, she coins a new term, the Tokyo paradigm, to show intriguing similarities and differences between Japanese law and laws of the EU and the USA. A part of her argument is here:
