Location Privacy of Wireless Local Area Network Users Using Client Server Based Architecture

Abstract

In this advance technology world communication can now easily be done via wireless communication infrastructure. Now users can easily avail communication services even while roaming into different places. Through the use of wireless communication infrastructure many of the techniques have been adopted to facilitate its users which include transmission security, voice and video services, user location identification etc. Due to advance researches and development in the wireless domain, location of any wireless user can now be collected using advance wireless location tracking techniques. There are so many such applications which are helpful providing user; information about different locations around them (i.e. restaurants, hotels, sport club, bar, masjid, market) however there are cases where it is necessary to protect the users location information from being used for some criminal activity. There are so many techniques have been adopted to prevent user location information from being collected such as dynamically changing the interface identifiers, manipulating the received signal and time values, so as to obfuscate the attacker in long term movements. This research discusses a technique through which user‟s location information can be altered so as to obfuscate the attacker. In this technique a middleware system that is carrying the record of all the RSSI (Received Signal Strength Identifier) values of each Wireless User connected to it sends the manipulated RSSI value to a source that is requesting for a location of WLAN / WCAN Users within its signal space.
