<p class=MsoNormal style='margin-left:.5in'>But I say MINIMUM functionality
because the companies who run those large sites certainly see opportunity in
other functionality the identity industry is pursuing, whether it be claims,
social integration, personal web services, etc. <o:p></o:p></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I’m guessing that ”opportunity” that we
analyzed the other day seems an examplar case of the value-add that folk
perhaps characterize as: “user-centric”.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>…leverage the ability to perform a cross-correlation search
to find “the other comments left at other commenting sites where a login
URL claim (openid) been used, given its been noted to have been used at change.gov”.

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>This is example of the ”other functionality” that
can be built, once one has the openid concept adopted pretty universally. It’s
a web2.5 application, leveraging the core web2.0 platform. And, like all web2.0,
it obviously relies on the data being in web-form (URLs) – a form that we
know make raw web data highly amenable to high-volume, search-based correlations
that drive search-powered applications.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>That example would seem to characterize a ”user-centric”
value-add that doesn’t exist …until one searches out the
correlations. And it clearly provides to the use a clear personal benefit: a cross-site
“central view” of all authenticated comments left by that _<i>one</i>_
openid user, despite leaving them on _<i>many</i>_ blog sites. Without said
benefit, only the many site-centric views would exist, leaving the actual
user/commentator at a relative disadvantage.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>If this is the user-centric-ness intended in openid/UCI, then I get
the meaning of the term. Use the sideeffects of URL-based correlations as a “technology”;
one from which one can variously rebuild the per-user view of their own
distributed weblife.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>At first blush, that conception makes it obvious why a google
would buy into openid. The side effect benefits go way, way beyond openid’s
pro forma benefits: providing crypto channel, addressing the user’s
multiple password problem, and form-filling for signups. Based on the URLness
of the openid, as with trackbacks et al, identity URLs get added to side-effect-of-search
“technologies”, that create the web2.0 computing platform.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>But, that is all a very different conception of the term UCI to the
one I had understood openid to be about -- one focused narrowly on classical security
controls theory. There, UCI is about providing the by-design assurance that a
mere OP has no inherent “trusted” role, and the identity metadata is
not a platform to vector trust-based control systems, by default. In that conception
of UCI, the denial of a trusted role for OPs “by default” characterizes
a world in which any one OP is unable to negatively impact the relationship between
an openid-empowered user and a the set of RPs being used by said user. This default
limitation is the crux of the “user” centeredness, of the control relationship.
Of course, nothing should or does stop one applying a trust overlay, by
consent of the parties.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Be fun to know what the design team actually intended UCI to
mean: security models or web2.0 benefits. It’s clearly the only thing that
fundamentally distinguishes the openid crowd from the typical SAML crowd.<o:p></o:p></span></p>
