OLBS: Offline Location Based Services [PDF]
2011 Fifth International Conference on Next Generation Mobile Applications, Services and Technologies, 2011 Most existing location-based services rely on ubiquitous connectivity to deliver location-based contents to the users. However, connectivity is not available anywhere at anytime even in urban centres. Underground, indoors, remote areas, and foreign countries are examples situations where users commonly do not have guaranteed connectivity but could ...

Hall of Mirrors: A Novel Strategy to Address Locality in Geocoded-Based PoI Private Queries
IEEE Access, 2022 Location privacy techniques try to protect user’s information by altering, aggregating or generalizing it. Geographical codification techniques, like Geohash, can be used to protect individual locations altering the precision of the location so it
