Perturbed anonymization: two level smart privacy for LBS mobile users

== Abstract ==

The use of smart mobile devices like tablets, smart phones and navigational gadgets provide most promising communication and better services to mobile users. Location Based Services (LBS) have become very common in recent years. Mobile users submit their location dependent queries to the untrusted LBS server to acquire a particular service. Ideally, user’s personal information such as location data is supposed to be protected while communicating to LBS and at the same time quality of service must be maintained. Therefore, there is a need to have a balanced trade-off between privacy and quality of service. To fulfil such trade-off, this paper proposes a solution that first forms the cloaking region at mobile device, perform perturbation to handle the problem of trusted third party and the anonymizer further anonymizes the location to remove the problem of enough users required to form the cloaking region. The proposed approach protects the location privacy of the user and also maintains the quality of service by selecting appropriate service to the particular user. The proposed algorithm provides two-level location protection to the user, and thus ensures smart mobility of the LBS user.
