The continuous expansion of diverse mobile devices with various kinds of integrated sensors, namely GPS receivers, different mobile communications technologies and along with these the ubiquitous availability of and access to the Internet fosters the development of Location-Based Services (LBS). Yet again trust, security and protection of the user’s privacy are important for the success of such...

The wide deployment of IEEE 802.11 Wireless Local Area Networks (WLANs) has made possible the development of application services on WLANs. Due to the small cell size in WLANs, it is practical to develop location dependent services based upon the awareness of the WLAN access points (AP) that mobile devices currently access. In this paper, we propose a location determination technique using the ...

As the sensitivity of position, privacy protection in both 5G positioning and its further application location-based services (LBSs) has been paid special attention studied. Solutions based on k-anonymity, homomorphic encryption, secure multi-party computation have proposed. However, these solutions either require a trusted third party or incur heavy overheads. Besides, there still lacks an int...
