Still following up on all the exiting new developments that could be seen at the World Wide Web conference, I gave a group-internal presentation today on OpenID. OpenID is an open, decentralized, free framework for user-centric digital identity. Web sites supporting OpenId let users identity by entering their URL (e.g. of their homepage) and delegate the authentication process to arbitrary identity providers. As a result, users can access many different sites using the same account, which has a lot of interesting implications on how data can be used across multiple applications.
