Privacy Preserving Geo Location& other “mystuff” services


Thursday 2C

Convener: Arman Maghbouleh

Notes-taker(s): Alan Gous


Discussion notes, key understandings, outstanding questions, observations, and, if appropriate to this discussion: action items, next steps:


Two use cases for looking after your things:

1. Improving privacy for geo-location tags

  • Current setup involves BLE tags (Tile, Trackr), communicating to gateways (cell phones) that add geolocation info and forward to a proprietary server. Users can access the server.
  • Sketched a more open, privacy-centric version:
    • Ephemeral IDs (EIDs) on BLEs
    • Gateways add geo-info cryptographically
    • Distributed Hash Table (DHT) bulletin board so gateways post EIDs and user apps query for these.
    • DHT has no ability to link users to the locations or data from things.

2. Attesting Ownership of Things

  • Discussed a DHT solution for registering, transferring ownership, verifying ownership of goods (eg camera with serial number), for lost+found and deterring theft.
  • Suggested interest from police services, insurance companies, pawn shops, etc
