Privacy for location data in mobile networks, a summary

• EU Directive 2002/58/EC has introduced, by means of Art. 9, special protection for location data other than traffic data. In this paper, we argue that also location data within traffic data can contain sensitive information about the relative positioning and co-located displacements of mobile nodes and thus alsorequires special protection.Brief discussions are given to how mobility is supported in IP networks, to the level of privacy protection for location data that was introduced in the new European Union data protection directive, and to means of protecting privacy by technology. The concept of \textit{co-located displacements inMobileIP} is introduced and we show how the home agent will be able to determine whether or not a set of mobile nodes move in a co-located fashion.Finally we present how, also for location information within traffic data, privacy-enhancing technologies can be used to provide the level of privacy protection that is required by Art. 9 of the EU Directive 2002/58/EC for location data other than traffic data.
