PRIVACY IN QUERY PROCESSING WITH ANONYMISER IN ROAD NETWORKS
V. Anandam · 2013
The rapid growth of location aware devices along with wireless communications and mobile databases results in realizing location-based applications that gives particular information to the users depending upon their current locations. Location-based store finder, location-based traffic reports, and location-based advertisements are the examples of location –based service applications. The main problem with location based services is revealing user locations which threaten the privacy and security of users and such services may also share private location information with other services. If a user wants to hide their location information then they has to turn off location aware device and also has to unsubscribe from the location based services. In regard with this issue, we in this paper introduce a frame work for query processing with an Anonymizer in road networks. We design the frame work in such a way to provide anonymous LBS access to the users and allow efficient query processing at the location based services side. The techniques discussed in this paper make use of the existing network database infrastructure without requiring specialized schemes or functionalities. The effectiveness of the frame work introduced in this paper can be demonstrated by comparing the experimental results with other alternative designs.
