Executive Summary

The pervasive diffusion of mobile communication devices and the technical improvements of location techniques are fostering the development of new applications that use the physical position of users to offer location-based services for business, social, or informational purposes. In such a context, privacy concerns are increasing and call for sophisticated solutions able to guarantee different levels of location privacy to the users. In this paper, the authors address this problem and present a solution based on different obfuscation operators that, when used individually or in combination, protect the privacy of the location information of users.
