"On the Internet, nobody knows you're a dog" (IIW logo)

    • e.g. username, password, auth token, etc.
    • SAML (Security Assertion Markup Language): Directory of employees with specific privileges
    • Authorization, or AuthZ (What you’re allowed to do)
  • Authentication, or AuthN (The identifier – the username you use, etc.)
  • Verification

OpenID = outsourcing username and password (same "username" or i-name)

  • Problem is phishing: Fake forms for OpenID providers
  • Therefore, OpenID is designed for low-security transactions

NASCAR problem: Addresses challenge of usability with OpenID (logos instead of having to remember your OpenID URL)

Info Cards

  • IDP issues card, or you make your own card
  • User selects cards
  • Open Source InfoCard Selector repository: Higgins Project
  • Send various attributes only, customize the amount of information sent

OpenID + Information Cards = Open Identity Exchange

XRD is Discovery: A protocol for understanding and discovering services

We then went over a bunch of the organizations and how they relate to each other. See Kaliya’s flowchart slides for an overview.
