Securing personal items in public space

Abstract

While we put great effort in protecting digital devices and data, there is a lack of research on usable techniques to secure personal items that we carry in public space. To better understand situations where ubiquitous technologies could help secure personal items, we conducted an online survey (N=101) in which we collected real-world stories from users reporting on personal items, either at risk of, or actually being lost, damaged or stolen. We found, for example, that the majority of cases occurred in (semi-)public spaces during afternoon and evening times, when users left their items. From these results, we derived a model of incidents involving personal items in public space as well as a set of properties to describe situations where personal items may be at risk. We discuss reoccurring properties of the scenarios, potential multimedia-based protection mechanisms for securing personal items in public space as well as future research suggestions.
