Privacy in Mobile and Pervasive Computing (Synthesis Lectures on Mobile and Pervasive Computing)

It is easy to imagine that a future populated with an ever-increasing number of mobile and pervasive devices that record our minute goings and doings will significantly expand the amount of information that will be collected, stored, processed, and shared about us by both corporations and governments. The vast majority of this data is likely to benefit us greatly—making our lives more convenient, efficient, and safer through custom-tailored and context-aware services that anticipate what we need, where we need it, and when we need it. But beneath all this convenience, efficiency, and safety lurks the risk of losing control and awareness of what is known about us in the many different contexts of our lives. Eventually, we may find ourselves in a situation where something we said or did will be misinterpreted and held against us, even if the activities were perfectly innocuous at the time. Even more concerning, privacy implications rarely manifest as an explicit, tangible harm. Instead, most privacy harms manifest as an absence of opportunity, which may go unnoticed even though it may substantially impact our lives.

In this Synthesis Lecture, we dissect and discuss the privacy implications of mobile and pervasive computing technology. For this purpose, we not only look at how mobile and pervasive computing technology affects our expectations of—and ability to enjoy—privacy, but also look at what constitutes "privacy" in the first place, and why we should care about maintaining it. We describe key characteristics of mobile and pervasive computing technology and how those characteristics lead to privacy implications. We discuss seven approaches that can help support end-user privacy in the design of mobile and pervasive computing technologies, and set forward six challenges that will need to be addressed by future research.

The prime target audience of this lecture are researchers and practitioners working in mobile and pervasive computing who want to better understand and account for the nuanced privacy implications of the technologies they are creating. Those new to either mobile and pervasive computing or privacy may also benefit from reading this book to gain an overview and deeper understanding of this highly interdisciplinary and dynamic field.

Marc Langheinrich is full professor in the Faculty of Informatics at the Università della Svizzera Italiana (USI) in Lugano, Switzerland. His research focuses on privacy in mobile and pervasive computing systems, in particular with a view towards social compatibility. Other research interests include usable security and pervasive displays. Marc is a member of the Steering Committee of the UbiComp conference series and chairs the IoT conference Steering Committee. He has been a General Chair or Program Chair of most major conferences in the field--including Ubicomp, PerCom, Pervasive, and the IoT conference--and currently serves as the Editor-in-Chief for IEEE Pervasive Magazine. Marc holds a Ph.D. from ETH Zürich, Switzerland.

Florian Schaub is an assistant professor in the School of Information and the Computer Science and Engineering Division at the University of Michigan. His research focuses on understanding and supporting people's privacy and security behavior and decision making in complex socio-technological systems. His research interests span privacy, human-computer interaction, and emergent technologies, such as the Internet of Things. Florian received a doctoral degree in Computer Science from the University of Ulm, Germany, and was a postdoctoral fellow in Carnegie Mellon University's School of Computer Science. His research has been honored with Best Paper Awards at CHI, the ACM SIGCHI Conference on Human Factors in Computing, and SOUPS, the Symposium on Usable Privacy and Security.
