• Anonymous Retrospective Broadcasts
  • If we don't assume a centralized party that can be trusted to verify information, what we're left with is not really a contact tracing application but a particular kind of messaging application, where users create tracks through space and time, and can retrospectively broadcast anonymous messages to users whose tracks were spatially nearby to theirs in a particular time range.
  • This messaging system should be privacy-preserving, in the sense that:
    • Server Privacy: An honest-but-curious server should not learn information about any user's space-time tracks;
    • Locality Integrity: A user should not be able to broadcast messages to users who were not nearby to them;
    • User Privacy:
      • A passive adversary cannot not learn any information about a user's space-time track outside of the segments they have broadcast messages to. This means that users who do not broadcast reveal no information about their movements.
