ABSTRACT
In this work, we define the Nearest Doctor Problem (NDP) for finding the closest doctor in case of an emergency and present a secure multi-party computation for solving it. The solution is based on a privacy-preserving cryptographic protocol and makes use of the current location of each participating doctor. The protocol is efficient and protects the privacy of the location of all doctors. A prototype implementing the proposed solution for a community of doctors that use mobile devices to obtain their current location is presented.

An efficient privacy-preserving solution for finding the nearest doctor
In this work, we define the Nearest Doctor Problem for finding the nearest doctor in case of an emergency and present a privacy-preserving protocol for solving it. The solution is based on cryptographic primitives and makes use of the current location ...
Preserving location privacy without exact locations in mobile services
Privacy preservation has recently received considerable attention in location-based services (LBSs). A large number of location cloaking algorithms have been proposed for protecting the location privacy of mobile users. However, most existing cloaking ...
An Oblivious Transfer Protocol Based on Elgamal Encryption for Preserving Location Privacy
Location based services (LBS) are applications that require a client's geographical location to provide a service or a piece of information that is related to the client at that location. Although LBSs promise safety and convenience, they threaten the ...
