Associate Professor (Maître de Conférences) at University of Versailles Saint-Quentin-en-Yvelines (UVSQ)

Member of the David Lab at UVSQ and Petrus (Personal and Trusted Cloud) team (successor of the SMIS team) at Inria Saclay Ile-de-France



In Petrus team, we investigate the Secure Personal Cloud. The Personal Cloud paradigm holds the promise of a privacy-by-design storage and computing platform, where each individual can gather her complete digital environment in one place and share it with applications and users, while preserving her control. However, this paradigm leaves the privacy and security issues in user's hands, which leads to a paradox if we consider the weaknesses of individuals' autonomy in terms of computer security, ability and willingness to administer sharing policies. To tackle this challenge, we identify four main lines of research:

a) Personal cloud server architectures. Based on the intuition that user control, security and privacy are key properties in the definition of trusted personal cloud solutions, our objective is to study how and to which extent technical architectural choices influence them.

b) Privacy preserving administration models and enforcement. This research axis is devoted to the definition of sharing rules that are easily manageable for the individual and enforced by default (i.e., secure implementation). Complementary to the definition of sharing policies, it is mandatory to help the average user regulate the complete lifecycle of her data, from its capture, to its dissemination and up to its deletion. This encompasses principles like limited data collection, secure storage, enforcement of sharing and usage policies and finally sustainability.

c) Global query evaluation. The goal of this line of research is to provide capabilities for crossing data belonging to multiple individuals (e.g., performing statistical queries over personal data, computing queries on social graphs or organizing participatory data collection) in a fully decentralized setting while providing strong and personalized privacy guarantees.

d) Economic, legal and societal issues. This research axis is more transversal and entails multidisciplinary research, addressing the links between economic, legal, societal and technological aspects.
