SACRAMENTO, Vagner; ENDLER, Markus  and  SOUZA, Clarisse de. A privacy service for location-based collaboration among mobile users. J. Braz. Comp. Soc. [online]. 2008, vol.14, n.4, pp.41-57. ISSN 1678-4804.

The potential loss of privacy due to the use of location-based applications may be one of the greatest obstacles to their wider acceptance. Nevertheless, most research about privacy management to-date has not taken into consideration the complexity in the utilization of collaborative applications that may require users' location sharing among participants. In this article, we propose a privacy service that helps users to maintain their privacy policy in a flexible and incremental way. We also carried out a qualitative evaluation study whose results illustrate several challenges that should be handled in the design of such a service.

Keywords : privacy; design of a privacy service; LBS applications; context-aware application; context-aware middleware.
