Privacy issues related to mobile and wireless Internet access

I just came across a research worth checking out by all the wardrivers and mobile/wireless Internet users out there. While it's written in 2004, "Privacy, Control and Internet Mobility", provides relevant info on an important topic - what kind of information is leaking and how can this be reduced. The abstract describes it as :



"This position paper explores privacy issues created by mobile and wireless Internet access. We consider the information about the users identity, location, and the serviced accessed that is necessarily or unnecessarily revealed observers, including the access network, interme- diaries within the Internet, and the peer endpoints. In particular, we are interested in data that can be collected from packet headers and signaling messages and exploited to control the users access to communications resources and online services. We also suggest some solutions to reduce the amount of information that is leaked."



A more in-depth overview on the topic can also be found in "A Framework for Location Privacy in Wireless Networks", an excerpt :



"For example, even if an anonymous routing protocol such as ANODR is used, an attacker can track a user's location through each connection, and associate multiple connections with the same user. When the user arrives at home, she will have left a trail of packet crumbs which can be used to determine her identity. In this paper, we explore some of the possible requirements and designs, and present a toolbox of several techniques that can be used to achieve the required level of privacy protection."



Mobile/Wireless location privacy would inevitable emerge as an important issue given the growth of that type of communication, and the obvious abuses of it.
