- A system for locating mobile terminals with tunable privacy Sandford Bessler Multidisciplinaria (Ciencias Naturales y Exactas) SIP GPS GML zones privacy A number of approaches for capturing and processing location information of mobile users have beenproposed in the past; however, only with the latest advances in the handset technology, a terminal-basedpositioning approach, using overlay SIP signaling on top of a packet switched bearer and area notification asbasic functionality becomes feasible for mass applications. Especially in electronic commerce scenarios, inwhich users often interact with non-trusted services and shops, any location-based solution has to considerprivacy aspects as well. The terminal-centric model presented in the paper leads to a simple and efficient wayto achieve tunable privacy: mobile users define own "zones" and selectively disclose them to their buddies andto external services. As a result, localization can be performed only in the allowed places and by the allowedwatchers, both parameters being configured by the user herself on her mobile terminal. We describe the systemarchitecture, protocols and present representative technical scenarios 2007 artículo científico 0718-1876 https://www.redalyc.org/articulo.oa?id=96520208 en http://www.redalyc.org/revista.oa?id=965 Journal of Theoretical and Applied Electronic Commerce Research application/pdf Universidad de Talca Journal of Theoretical and Applied Electronic Commerce Research (Chile) Num.2 Vol.2
