Identity in technology
• Simply an identifier correlated with credentials
– majority of identity identifiers are local identifiers
– majority of identity credentials are passwords
• Identity can be correlated with attributes either
self-asserted or externally verified
• Attributes can be used to process access
policies
• Identity identifiers can be used for
personalization

OpenID
• OpenID offers globally unique identifiers
(URLs) for identity rather than local identifiers
• OpenID SREG enables self-asserted attributes
for the purposes of registering on new sites
• OpenID providers offer the credential checking
(which is optional)
• OpenID doesn’t guarantee the validity of any
user attributes

OpenID
• Board includes Google, Microsoft, IBM,
VeriSign, Yahoo!, Sxip, SixApart…
• Around 10,000 sites support it
• Integrated into lots of products: Drupal,
MediaWiki, Wordpress…
• Approx. 250,000,000 OpenIDs created

“ The bottom line: OpenID is a disuptive
technology that allows web sites to
share identity information and
streamline authentication processes.
Enterprises with a significant online
presence can increase contact with
their customers by adopting OpenID.”
- Andrew Jacquith, Yankee Group

Why is OpenID interesting?
- Slide 9: QuickTimeᆰ and a
institute for educational cybernetics
TIFF (LZW) decompressor
are needed to see this picture
it isn’t really an authentication
system
That’s a good thing
- Slide 10: QuickTimeᆰ and a
institute for educational cybernetics
TIFF (LZW) decompressor
are needed to see this picture
it doesn’t really verify identity or
identify the user
That’s a good thing too
- Slide 11: QuickTimeᆰ and a
institute for educational cybernetics

are needed to see this picture
it doesn’t require or assume
policy alignment or trust
Nice and flexible…
- Slide 12: QuickTimeᆰ and a
institute for educational cybernetics

it isn’t a provisioning system
(Apart from SREG and AE, but
they aren’t mandatory)
- Slide 13: QuickTimeᆰ and a
institute for educational cybernetics

All it does is offer a means of
asserting a relationship
between an agent and a URL
h o w c o o l is t h a t ?
- Slide 14: QuickTimeᆰ and a

This makes it a potential
boundary mechanism for the
coordination of individual, self-
organised, and managed
activity
- Slide 15: QuickTimeᆰ and a

OpenID is a pivot
• It can provide an axis of coordination
between the formal system and
informal systems
• OpenID actually doesn’t really
authenticate or identify anyone, but
it can connect things that use
identity

assessment or for personal portfolio
development

engagement without institutional commitment
Coordination of home/work/university boundary
activities
Tracking activity for coordination at
group/course level
