SHARP: Private Proximity Test and Secure Handshake with Cheat-Proof Location Tags
A location proximity test service allows mobile users to determine whether they are in close proximity to each other, and has found numerous applications in mobile social networks. Unfortunately, existing solutions usually reveal much of users’ private location information during proximity test. They are also vulnerable to location cheating where an attacker reports false locations to gain adva...
متن کاملLocation Privacy via Private Proximity Testing
We study privacy-preserving tests for proximity: Alice can test if she is close to Bob without either party revealing any other information about their location. We describe several secure protocols that support private proximity testing at various levels of granularity. We study the use of “location tags” generated from the physical environment in order to strengthen the security of proximity ...

Both actors want to leverage location-based services utility without sacrificing privacy. We propose a protocol that sup...
متن کاملEfficient Private Proximity Testing with GSM Location Sketches
A protocol for private proximity testing allows two mobile users communicating through an untrusted third party to test whether they are in close physical proximity without revealing any additional information about their locations. At NDSS 2011, Narayanan and others introduced the use of unpredictable sets of “location tags” to secure these schemes against attacks based on guessing another use...
