Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 23242 "Privacy Protection of Automated and Self-Driving Vehicles". While privacy for connected vehicles has been considered for many years, automated and autonomous vehicles (AV) technology is still in its infancy and the privacy and data protection aspects for AVs are not well addressed. Their capabilities pose new challenges to privacy protection, given the large sensor arrays that collect data in public spaces and the integration of AI technology. During the seminar, several keynote presentations highlighted the research challenges from different perspectives, i.e. legal, ethical, and technological. It was also discussed extensively why vehicles need to make dynamic assessments of trust as an enabling factor for the secure communication and data sharing with other vehicles, but without increasing any privacy risks. Then, the main objective of the seminar was to produce a research road-map to address the major road-blockers in making progress on the way to deployment of privacy protection in automated and autonomous vehicles. First, the group identified six common scenarios of Cooperative, Connected and Automated Mobility (CCAM) during development and product life-cycle, and analyzed the privacy implications for each scenario. Second, it formulated the need to have a methodology to determine the cost-benefit trade-offs between privacy and other criteria like financial, usability, or safety. Third, it identified existing tools, frameworks, and PETs, and potential modifications that are needed to support the automotive industry and automotive scenarios. Finally, the group explored the interplay between privacy and trust, by elaborating on different trust properties based on performance, on ethical aspects, and on user acceptance.

Privacy Protection of Automated and Self-Driving Vehicles (Dagstuhl Seminar 22042)

Authors: Frank Kargl, Ioannis Krontiris, André Weimerskirch, Ian Williams, and Nataša Trkulja

Published in: Dagstuhl Reports, Volume 12, Issue 1 (2022)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 22042 "Privacy Protection of Automated and Self-Driving Vehicles". The Seminar reviewed existing privacy-enhancing technologies, standards, tools, and frameworks for protecting personal information in the context of automated and self-driving vehicles (AVs). We specifically focused on where such existing techniques clash with requirements of an AV and its data processing and identified the major road blockers on the way to deployment of privacy protection in AVs from a legal, technical, business and ethical perspective. Therefore, the seminar took an interdisciplinary approach involving autonomous and connected driving, privacy protection, and legal data protection experts. This report summarizes the discussions and findings during the seminar, includes the abstracts of talks, and includes a report from the working groups.

'My Life, Shared' - Trust and Privacy in the Age of Ubiquitous Experience Sharing (Dagstuhl Seminar 13312)

Authors: Alessandro Acquisti, Ioannis Krontiris, Marc Langheinrich, and Martina Angela Sasse

Published in: Dagstuhl Reports, Volume 3, Issue 7 (2013)

Abstract
Many researchers have already begun using personal mobile devices as personal "sensing instruments" and designed tools that reposition individuals as producers, consumers, and remixers of a vast openly shared public data set. By empowering people to easily measure, report, and compare their own personal environment, such tools transform everyday citizens into "reporting agents" who uncover and visualize unseen elements of their own everyday experiences. This represents an important new shift in mobile device usage - from a communication tool to a "ubiquitous experience sharing instrument". This report documents the program and the outcomes of Dagstuhl Seminar 13312 "My Life, Shared" - Trust and Privacy in the Age of Ubiquitous Experience Sharing, which brought together 33 researchers and practitioners from multiple disciplines -- including economics, psychology, sociology, as well as various fields within the discipline of computer science dealing with cryptographic feasibility, scalability and usability/acceptability -- to discuss opportunities and challenges of sharing information from the pervasive environment.

Online Privacy: Towards Informational Self-Determination on the Internet (Dagstuhl Perspectives Workshop 11061)

Authors: Simone Fischer-Hübner, Chris Hoofnagle, Ioannis Krontiris, Kai Rannenberg, and Michael Waidner

Published in: Dagstuhl Manifestos, Volume 1, Issue 1 (2011)

Abstract
While the collection and monetization of user data has become a main source for funding ``free'' services like search engines, online social networks, news sites and blogs, neither privacy-enhancing technologies nor its regulations have kept up with user needs and privacy preferences. The aim of this Manifesto is to raise awareness for the actual state of the art of online privacy, especially in the international research community and in ongoing efforts to improve the respective legal frameworks, and to provide concrete recommendations to industry, regulators, and research agencies for improving online privacy. In particular we examine how the basic principle of informational self-determination, as promoted by European legal doctrines, could be applied to infrastructures like the internet, Web 2.0 and mobile telecommunication networks.
