Prof. P Krishna Reddy and his students Shadaab Siddiqie and Srinivas Reddy Annappalli published their research work on Location and Intent Privacy Preservation for Spatial Range Queries in a Mobile Network in IEEE Access. Here is the summary of the paper as explained by the authors:

Location-based services (LBSs) in a mobile network environment that provide personalized and timely information to users entail privacy concerns due to the leakage of user locations to adversaries. In the literature, several cloaking-based privacy preservation approaches have been proposed by considering the P2P environment. However, existing spatial cloaking approaches form a large cluster of mobile users to cloak the user query location. Maintaining such structures in a highly dynamic mobile-P2P network is challenging. In addition to the user’s location, the user’s intent is also an important concern and needs to be preserved from an adversary. This paper proposes a location privacy and intent privacy preservation scheme, especially for spatial range queries. The key contributions of our work are three-fold. First, we introduce the concept of ijk -anonymity to achieve improved location privacy. Second, we propose a location-based privacy-preservation approach, which we designate as ijk Cloak, for spatial range queries in a mobile network environment. The proposed approach preserves user location and intent information from the LBS provider and nearby peers. Third, we conduct theoretical analysis and experiments on resistance to attacks. We show that ijk Cloak effectively facilitates improved user location privacy and intent privacy by employing fewer peers w.r.t. existing approaches.
