Abstract: Today’s location-sensitive service depends on user’s mobile device to determine the current location. This leads malicious users to access restricted resource by cheating on their locations. To resolve this, proposed A Privacy-Preserving location proof Updating System (APPLAUS) in which collocated Wi-Fi enabled systems mutually generate location proofs and send updates to a location proof server. Periodically changed pseudonyms are used by the systems to protect source location privacy from each other, and from the untrusted location proof server. Also developed user-centric location privacy model where the individual users evaluate their location privacy levels and decide whether and when to accept location proof requests. APPLAUS can be implemented with existing network infrastructure, and can be easily deployed in Wi-Fi enabled systems with low power cost. Further experimental results show that APPLAUS can effectively provide location proofs, significantly provide source location privacy, and it detects colluding attacks.
