A system and method for providing proximity information
The present invention relations to a system and method for providing proximity information, and particularly, although not exclusively, to a system and method for providing proximity information to users in mobile geo-social networks.
Protecting users' location privacy
For providing proximity information to users in mobile geo-social networks.
There is provided a method for providing proximity information comprising the step of processing a location data set having locations of a plurality of objects in a network space by applying a grid and hashing paradigm to the locations of the plurality of objects so as to generate a proximity set arranged to represent one or more proximity relationships between the one or more objects in the network space wherein, the grid and hashing paradigm is arranged to transform the locations of the plurality of objects in the network space onto a multi-layered grid model arranged to model the network space so as to generate a plurality of signatures each associated with each of the plurality of objects in the multi-layered grid model.

Title: SYSTEM AND METHOD FOR PROVIDING PROXIMITY INFORMATION
Usefulness: SYSTEM AND METHOD FOR PROVIDING PROXIMITY INFORMATION
Summary: Method for providing proximity information to users in mobile geo-social networks such as Facebook (RTM: online social networking service), or specialized vendors e.g. Foursquare (RTM: local search and discovery service mobile app), Gowalla (RTM: location-based social network) or Loopt (RTM: location-based social network), for privacy-preserving proximity detection.
Novelty: Method for providing proximity information to users in e.g. Facebook, involves arranging grid and hashing paradigm to transform locations of objects in network space onto grid model arranged to model network space for generating signatures
