Hi all, The University of Amsterdam (UvA) is looking for a PhD student on the topic of "Accountable Usage Control for Distributed Data Processing Systems". The research touches on the fields of distributed systems, software engineering, access/usage control, and (domain-specific) programming languages. Please consider this vacancy or forward it to people who may be interested. A short summary can be found below. The full vacancy can be found here: PhD Position in Accountable Usage Control for Distributed Data Processing Systems Functiedetails | UvA<https://vacatures.uva.nl/UvA/job/PhD-Position-in-Accountable-Usage-Control-for-Distributed-Data-Processing-Systems/797075602/>. Kind regards, dr. Thomas van Binsbergen Assistant Professor Informatics Institute University of Amsterdam The Complex-Cyber Infrastructure (CCI) group of the UvA brings together research on several topics to advance the state of the art in data exchange systems – such as privacy, security, usage control, software languages, legal compliance, and normative (software) systems. By combining advancements in these areas, the CCI group proposes novel data exchange solutions in which organisations retain control over the data assets they offer, and the risk of data exchange is reduced through, for example, compliance with (privacy) regulations and security requirements. These solutions are brought into practice with industrial and societal partners within the Amsterdam Data Exchange (AMdEX) consortium. The goal of this PhD position is to conduct fundamental research into novel distributed usage control models with high degrees of accountability, transparency, and human involvement (human-in-the-loop), whilst satisfying (other) legal requirements such as the handling of legal obligations and pre- and post-conditions on the usage of data assets. A particular challenge follows from the distributed nature of the studied systems – information required to make and justify access and usage decisions may be highly dispersed across the system and some of this information might itself be sensitive.
