| Popis: | There are two popular location-based service (LBS) applications: searching k-nearest neighbor Points of Interests (kNN POIs) and finding Nearby Friends (NF) via a social network server (SNS). Nevertheless, both applications are based on users’ current locations, and no scheme has been devised yet to merge POIs, NF and SNS together. A series of works were proposed to preserve users’ query privacy leaked from service attributes of POIs or location privacy over Mobile Social Networks (MSNs). However, their communication and computation costs are heavy. |
