DGS-HSA: A Dummy Generation Scheme Adopting Hierarchical Structure of the Address
Applied Sciences, 2020 With the increasing convenience of location-based services (LBSs), there have been growing concerns about the risk of privacy leakage. We show that existing techniques fail to defend against a statistical attack meant to infer the user’s location privacy

Disaster Recovery (After Catastrophes) [PDF]
, 2021 This chapter examines approaches to disaster response critically. It compares ‘owner-driven’ and ‘community-ownership’ approaches to recovery policy taken by two different cities in the Indian state of Gujarat following the devastating 2001 Gujarat earthquake. Each model recognizes a different compositional context of agents, temporalities, and effects,
