This paper introduces results of a study into the value of location privacy for individuals using mobile devices. We questioned a sample of over 1200 people from five EU countries, and used tools from experimental psychology and economics to extract from them the value they attach to their location data. We compare this value across national groups, gender and technical awareness, but also the perceived difference between academic use and commercial exploitation. We provide some analysis of the self-selection bias of such a study, and look further at the valuation of location data over time using data from another experiment.

Abstract.What are the real security issues for a wireless sensor network (WSN) intended to monitor the structural health of a suspension bridge, a subway tunnel or a water distribution pipe? Could an attack on the sensor network cause the structure to collapse? How easy is it for civil engineers or other domain experts to build a secure WSN using commercially available hardware and software? We answer these questions by conducting a qualitative risk assessment with bridge and subway tunnel operators and by conducting penetration testing on commonly available commercial WSN hardware and software, namely the Crossbow MICAz motes running TinyOS and XMesh and communicating over IEEE 802.15.4.
