Geo-Locating Tweets with Latent Location Information
… Since many tweets talk about events (with useful location information), such as natural disasters, emergencies, and accidents, it is important to geo-locate those tweets whenever possible. Due to possible location ambiguity, finding a tweet's location often is challenging. Many distinct places …

An architecture and protocol, an access control model, and a sighting blurring algorithm for improving users' security in the context of location based services operating over the internet
A new type of service, known as a Location Based Service (LBS), is emerging that incorporates users' location information, and many of these LBSs operate over the Internet. However, the potential misuse of this location information is a serious concern. Therefore, the main goal of this thesis is to …

Providing Location Security in Vehicular Ad Hoc Networks
<p>Location is fundamental information in Vehicular Ad-hoc Networks (VANETs). Almost all VANET applications rely on location information. Therefore it is of importance to ensure location information integrity, meaning that location information is original (from the generator), correct (not bogus or …
