Quantifying privacy in terms of entropy for context aware services
Athanasios S. Voulodimos, Charalampos Z. Patrikakis · Identity in the Information Society · 2009
In this paper, we address the issue of privacy protection in context aware services, through the use of entropy as a means of measuring the capability of locating a user’s whereabouts and identifying personal selections. We present a framework for calculating levels of abstraction in location and personal preferences reporting in queries to a context aware services server. Finally, we propose a methodology for determining the levels of abstraction in location and preferences that should be applied in user data reporting during service provision, according to her personal privacy settings.
