Privacy-Oriented Analysis of Ubiquitous Computing Systems: A 5-D Approach

Ubiquitous computing systems are commonplace. They have opened the door to great benefits for society as a whole. However, they have to be used with care, otherwise they can cause serious risks for their users. In this chapter, we analyze the privacy risks of ubiquitous computing systems from a new individual-centred perspective based on five privacy dimensions, namely identity, location, footprint, query and intelligence. We describe each dimension and provide an introductory view of the main privacy risks of these systems. Also, we discuss some of the challenges that derive from new trends in the field.
