Nearby peer discovery without GPS using environmental fingerprints

I propose a peer discovery technique to detect nearby devices by comparing similarity in their observed environments, such as WiFi or Bluetooth networks. Using locality-sensitive hashing and private set intersection, peers can compare their environments without disclosing the full details. With sufficient similarity between environments, peers can conclude they are near each other.
