SAML and OpenID at the Convergence Dance

You have to be not just an identity geek, but a dedicated addressing geek, to have even heard of Zooko’s Triangle, let alone understand how elegant an analysis it is of the tradeoffs involved with global identifiers (globally-unique, human-meaningful, decentralized: … Continue reading

Eve riffs on SAML, OpenID, XRI, and privacy

Identity in context

“Context” has become the second-most-commonly used word in the identity industry after “identity” itself. And rightly so, since its practically mantra now that identity only exists in context, and — at least for people — is so incredibly context-sensitive. Paul … Continue reading

I-Names Get Real
