Design and development of privacy preserving architecture for mobile users

Nowadays, Smartphone's are being more and more popular as technology is being evolve. Smartphone's are capable for providing numerous services, such as Location Aware services like GPS. They share all the location information of the user to the server. Whenever user submit any query to location aware service, those queries also carries some personal information about user. The query and information is then submitted of LBS server. Someone at server's side may use this information to make user panic. To overcome this, new collaborative approach to hide users personnal data from LBS serve is introduced. An Adversary at LBS may misuse this location information and may plan an attack. Hence Users privacy is a issues to be resolved. We address this difficult by offering a system where user will not be exposed to the LBS, that is users identity and location would be hidden from the server. By using Third Party server we will hide User from Service provider. The solution does involve not alter the LBS server architecture but assume third party servers to significantly increase users' location privacy. To enhance privacy of user, we will add registration and verification system to the model, so that only authenticated users would ask for query response. By this Registration system we will be generating ID's, through that ID's interaction between user and LBS would happen, by which LBS would never know use's original identity and from which user location queries are fired. This prototype helps to examine the effects of several constraints, such as querying rates of user and the lifespan of context information, on users' location privacy.
