OpenID; user-centric identity
I am one of those who discovered OpenId very late. It's a shame; I have to live with it....OpenId is decentralized and user-centric identity framework. It seems to be easy to use and implement. The number of OpenId enabled sites (consumers) supports this claim; openiddirectory.com host list of them.
Wikipedia provides good introductions about OpenId to whom are new, like me. I also found a lot of technical details at here.
Another good news is OpenSSO provides OpenId implementation under OpenSSO Extensions project; consequently we can use OpenSSO as OpenId provider as well.
