Privacy protection in location-based services: A survey

Abstract

Location awareness has enabled efficient and accurate geo-localised Internet services. Mobile apps exploiting these services have changed our way of navigating and searching for resources in geographical space. This chapter provides a classification of location based services (LBS) and illustrates the privacy aspects involved in releasing our location information as part of a service request. It includes a discussion about legal obligations of the LBS provider and about ways to specify personal location privacy preferences. The chapter also provides a systematic survey of the main approaches that have been proposed for protecting the user's privacy while using these services.
