Semantics in Location-Based Services
Advances in wireless networks and mobile devices have motivated an intensive research effort in mobile computing and mobile data services. The goal is to provide users with anywhere and anytime connectivity to the Internet and access to services that are valuable according to the context of the user. One of the most interesting context factors is the location of the user. Thus, context-awarenes...
متن کاملData Semantics in Location-Based Services
Abstract. As location-based applications become part of our everyday life, ranging from traffic prediction systems to services over mobile phones providing us with information about our surroundings, the call for more semantics and accurate services is emerging. In this work, we analyze and register the data semantics of Location-based Services (LBS). Initially, we categorize LBS data according...
متن کاملMatching User's Semantics with Data Semantics in Location-Based Services
Mobility is having a tremendous impact on the design and use of information technology. Information services, in particular, are heavily challenged by this new framework, which calls for innovative solutions. One of the major issues for flexible information services is how to be able to correctly understand what is being requested by users, and how to find information that is relevant to the re...
متن کاملLocation Depersonalization for Location Privacy Protection in Location-Based Services
A spatial region with K different footprints indicates that it has been visited by K different people. An adversary may be able to identify all these users, but will not know who was there at what time. This observation gives us a new direction to investigate location depersonalization in location-based services (LBSs). We propose to leverage users’ historical location samples, each being a foo...
متن کاملLocation Privacy in Location-Based Services: Beyond TTP-based Schemes
Location-Based Services (LBS) are gaining importance due to the advances in mobile networks and positioning technologies. Nevertheless, the wide deployment of LBS can jeopardise the privacy of their users, so ensuring user privacy is paramount to the success of those services. This article surveys the most relevant techniques for guaranteeing location privacy to LBS users. The rigid dichotomy b...
