  2. Location retrieval • 4 different types of location retrieval: • location only • URL representing “Salon 1, Westin, 1601 Bayshore Drive, Vancouver” • e.g., http://ietf.org/ietf70/salon1 • no identity • target + location + time (“snapshot”) • request: “where was alice@example.com at 10:56 PST” • ask twice, get same answer even if target moved • may have limited storage time • target + “now” • request: “current location for alice@example.com” • ask twice, get two answers if target moved • may have limited time (observation period) • generic • “location service for Columbia U.” • ask any number of times • possibly infinite lifetime of URL GEOPRIV

  3. Yet another mode • Log retrieval • “where has the target been between 1800 and 1900” • target and LIS may keep limited history, so may fail GEOPRIV

  4. Graphical version target time location target “now” target target “then” GEOPRIV

  5. URLs • URL that provides value to anybody • e.g., crypto-randomized URL • security = security of conveying URL • URL that provides location to specific IP address • URL that requires auth^2 • HTTP • e.g., service GEOPRIV
