2C/ Privacy – Preserving Geo Location & Other “mystuff” Services
Privacy Preserving Geo Location& other “mystuff” services
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
