Summary: We prove our physical identity with a driver's license but how do we substantiate our digital web identity? We all circulate our online user names and passwords amid the growing concern of potential privacy invasion. At O'Reilly's 2006 Emerging Technology Conference, Dick Hardt discusses Identity Management history from the cumbersome interfaces of the 1980's to the needs of today's Web 2.0 applications. His company's new SXIP 2.0 protocol for automating the exchange of identity data on the Internet offers a simple solution for access and usability of webservices. Identity is who we and what we are conveyed by what we say about ourselves. Digital identity is the information we fill in when we register anywhere online. There is a necessary trust between sites; the identity provider has all the data and the service provider wants that identity data. But what choice does the user have? Identity 2.0 is a user-centric model that lets the user provide information to a credential provider allowing for scaleable flexibility. In his talk, Hardt explains the in-depth workings of his technology.
