Personalized location-based services [PDF]
Proceedings of the 2011 iConference, 2011 Location-Based Services (LBS) are based on a combination of the inherent location information about specific data, and/or the location information supplied by LBS clients, requesting location-specific and otherwise customized services. The integration of location-annotated data with existing personal and public information and services creates ...

DGS-HSA: A Dummy Generation Scheme Adopting Hierarchical Structure of the Address
Applied Sciences, 2020 With the increasing convenience of location-based services (LBSs), there have been growing concerns about the risk of privacy leakage. We show that existing techniques fail to defend against a statistical attack meant to infer the user’s location privacy

Location Prediction Based on a Sector Snapshot for Location-Based Services [PDF]
Journal of Network and Systems Management, 2013 In location-based services (LBSs), the service is provided based on the users' locations through location determination and mobility realization. Most of the current location prediction research is focused on generalized location models, where the geographic extent is divided into regular-shaped cells.
