Overview:

Mobile computing enables users to compute and communicate almost regardless of their current location. However, as a side effect this technology considerably increased surveillance potential for user movements. Current research addresses location privacy rather patchwork-like than comprehensively. Thus, this paper presents a methodology for identifying, assessing, and comparing location privacy risks in mobile computing technologies. This paper applies the approach to IEEE 802.11b wireless LAN networks and location-based services, where it reveals significant location privacy concerns through link- and application-layer information. From a technological perspective, it argues that these are best addressed through novel anonymity-based mechanisms.
