Defend Location Isolation Attacks with Enhanced Privacy Techniques

  Sekhar Babu Murakonda,  E Sravan Yadav

Privacy protection has recently received considerable attention in location-based services. A large number of location cloaking algorithms have been proposed for protecting the location privacy of mobile users. Then consider the scenario where different location-based query requests are continuously issued by mobile users while they are moving. Then the most of existing k-anonymity location cloaking algorithms are concerned with snapshot user locations only and cannot effectively prevent location-dependent attacks when users’ locations are continuously updated. Therefore, adopting both the location k-anonymity and cloaking granularity as privacy metrics, The new incremental clique-based cloaking algorithm, called ICliqueCloak, to defend against location-dependent attacks is introduced. The main idea is to incrementally maintain maximal cliques needed for location cloaking in an undirected graph that takes into consideration the effect of continuous location updates. Thus, a qualified clique can be quickly identified and used to generate the cloaked region when a new request arrives. The efficiency and effectiveness of the proposed ICliqueCloak algorithm are validated by a series of carefully designed experiments. The experimental results also show that the price paid for defending against location-dependent attacks is small and maintaining security along with the data management of the database for the user end.
