An Obfuscation-Based Approach For Protecting Location Privacy

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. The concept of location privacy can be defined as the right of individuals to decide how, when, and for which purposes their location information can be released to other parties. The physical location of users is rapidly becoming easily available as a class of personal information that can be processed for providing new online and mobile services, generally called Location-Based Services (LBSs). Customer oriented applications, social networks, and monitoring services can be greatly enriched with data reporting where people are, how they are moving, or whether they are close to specific locations. 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 project, we 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.
