Enter the Semantic Web: Reasoning details

  1. Look at server's policy to see if it satisfies user's preferences.
    • Do we hold the credentials to satisfy the request?
    • Is releasing them consistent with our preferences?
  2. How to prove we're over 18: Passport, Driver's License, Social Security card?
  3. Maximize privacy, minimize linkability.
    • Management of pseudonyms
    • Passport, Driver's license
  4. Client to server:
    • Here's proof that I have a driver's license.
    • Please remember you promised to delete this after 48 hours and notify me
  5. Server to client: Got it!
