Remark 1: in the first run, the app must be authorized by Facebook or LinkedIn ![]() If you are running the app for the very first time, make sure that you have Internet connectivity The protocol outputs number of hops in the social network graph between two users. SoPaL is based on the usage of higher order “bearer capabilities” (generated via a hash chain) as inputs to the Social Path Discovery protocol (extension to the original Friend Finder protocol). Since version 1.4, the application provides also the functionality of social path length discovery ( SoPaL) between any two users that are up to 4 hops from one another in the social network graph. They are distributed and managed using a social network application based on PeerShare. Bearer capabilities serve as proofs of friendship in a social network (currently only Facebook and LinkedIn are supported). The Friend Finder protocol is a private set intersection protocol that takes a list of “bearer capabilities” (time-limited random nonces), from each party as inputs, and outputs the list of common friends to both parties. ![]() The functionality of friend finding is based on a novel Friend Finder protocol which allows two users to find common friends in a privacy-preserving manner. The whole communication system does not depend on any infrastructure, and mobile devices act as network routers.įeatures related to the social relationship discovery are divided into two parts: friend finding and social path length discovery. The underlying network communication is provided by the SCAMPI router, which is DTN-based and runs the Epidemic routing protocol to distribute data in the local network. How Far Removed Are You?

In addition, it also provides the functionality of privacy-preserving social relationship discovery. The nearbyPeople app lets you discover and chat with people around you.
