Privacy Itch and Scratch

Ubiquitous computing technologies are being used to collect, process and share increasing amounts of personal information, from our location and physical activity levels to the things we buy and the web pages we read.  Although these developments have created a wealth of new applications that engage and entertain us, they also pose significant challenges for our privacy - particularly the challenge of maintaining awareness and control over our personal information flows as we go about our daily lives.

My colleagues, Vikram Mehta, Blaine Price and Bashar Nuseibeh, and I have been exploring new interaction metaphors for enhancing our privacy awareness and control.  Our earlier work in this area used haptic interactions through the users' smartphone to enable privacy controls to be configured by physically shaking and moving the device (PrivacyShake).   More recently we have been exploring the role of on-body interfaces to achieve more subtle and non-intrusive mechanisms for privacy …

Learning Privacy Norms for Social Software

Privacy Dynamics: Learning Privacy Norms for Social Software from Arosha Bandara
The slides above are from a presentation of our work on learning privacy norms for social software at the Symposium on Engineering Adaptive and Self-Managing Systems (SEAMS) in Austin, Texas.  The paper describes an architecture for integrating privacy management capabilities into social applications that integrate sharing functionality using social media platforms like Facebook.  The following summary is extracted from the abstract of the paper that accompanies this presentation:

Privacy Dynamics, is an adaptive architecture that learns privacy norms for different audience groups based on users’ sharing behaviours. Our architecture is underpinned by a formal model inspired by social identity theory, a social psychology framework for analysing group processes and intergroup relations. Our formal model comprises two main concepts, the group membership as a Social Identity (SI) map and privacy norms as a set…
