Privacy-Preserving Event Stream Processing in the Cloud
Prof. Pascal Felber,
Université de Neuchâtel,
Institut d’informatique –
Stream processing provides an appealing paradigm for building
large-scale distributed applications. Such applications are often
deployed over multiple administrative domains, some of which may not
be trusted. Recent attacks in public clouds indicate that a major
concern in untrusted domains is the enforcement of privacy. In this
talk we will primarily focus on the problem of content-based routing
(CBR), which is at the core of many event stream processing systems.
By routing data based on subscriptions evaluated on the content of
publications, CBR systems can expose critical information to
unauthorized parties. Information leakage can be avoided by the means
of privacy-preserving filtering, which is supported by several
mechanisms for encrypted matching. Unfortunately, existing approaches
have in common a high performance overhead and the difficulty to use
classical optimization. We will present and discuss mechanisms that
greatly reduces the cost of supporting privacy-preserving filtering
based on encrypted matching operators.
Pascal Felber received his M.Sc. and Ph.D. degrees in Computer Science from the Swiss Federal Institute of Technology. From 1998 to 2002, he has worked at Oracle Corporation and Bell-Labs (Lucent Technologies) in the USA. From 2002 to 2004, he has been an Assistant Professor at Institut EURECOM in France. Since October 2004, he is a Professor of Computer Science at the University of Neuchâtel, Switzerland, working in the field of dependable and distributed systems. He has published over 100 research papers in various journals and conferences.

INESC Brussels HUB Winter Meeting | JAN 25-26, 2024, in Porto
The INESC Winter Meeting, organized in collaboration with INESC Holding, is scheduled for January 25th and 26th, 2024, and it will be held in the city of Porto.
On January 25th, the primary goal is to bring together individuals from all five INESC institutes, fostering an environment that encourages networking, forging new connections, and collectively engaging in a forward-thinking exercise regarding the future of our research fields and the positioning of the INESC group within the European landscape.
There will be a welcome lunch, followed by an afternoon dedicated to collaboration, openness, and curiosity. The event will have a participatory approach, and will be guided by Dirk Stockmans, a highly experienced facilitator who has worked for the European Commission for the last 30 years.
Furthermore, all INESC researchers are invited to submit proposals for e-posters to be displayed at the Winter Meeting. Deadline for submissions is December 10 and more information is available here.
On January 26th, a senior administration and management committee will be held. Participants will be selected by each institute administration by invitation only.
If you would to take part on the 25th of January, please register here by November 30th.
The INESC Brussels HUB website will soon share more information about the venue and uptaded agenda.
