Title:        Efficient and Privacy-aware Mobile Sensing



Abstract: Sensor data are essential for many context-aware applications such as location-based services, environmental monitoring, or smart cities. Based on our current research at the University of Stuttgart, we are going to discuss three challenges in providing sensor data for context-aware systems in this talk.


First, we introduce public sensing concepts for gathering sensor data by crowds of smartphones that are utilized as networked mobile sensors. In particular, we focus on the question how to optimize the energy consumption of mobile sensing, which is an important prerequisite for users to participate in public sensing systems with their battery-operated mobile devices.


Secondly, we discuss how to store private location information of mobile users in a system of untrusted servers such as public cloud services. To this end, we introduce the concept of secure position sharing that distributes obfuscated location information among a set of servers of different providers to reduce the risk of revealing private information to compromised servers.


Thirdly, we present concepts for the efficient in-network processing of large streams of sensor data in an overlay network of data processing operators. We show that the network load can be reduced significantly by optimizing the placement of these operators on a set of distributed servers in the network.



Bio: Frank Dürr is a senior researcher and lecturer at the Distributed Systems Department of the Institute of Parallel and Distributed Systems (IPVS) at the University of Stuttgart. He received his doctoral degree and diploma in computer science both from the University of Stuttgart. Currently, he is leading the mobile context-aware systems group of the Department of Distributed System at the University of Stuttgart. Frank Dürr's research interests include mobile and pervasive computing, location privacy, and communication networks, in particular, the optimization of overlay networks, datacenter networks, and software-defined networking. He published more than 40 papers on related conferences and journals like IEEE International Conference on Pervasive Computing and Communications (Percom), ACM Conference on Ubiquitous Computing (UbiComp), IEEE Cloud, and the International Journal on Very Large Databases (VLDB Journal).
