Identity 2.0 = project for a global Digital Identity infrastructure, i.e. a Identity Commons


"Identity 2.0 is all about users controlling their own profile data and becoming their own agents. This way the users themselves, rather than other intermediaries, will profit from their ID info. Once developers start offering single sign-on to their users, and users have trusted places to store their data—which respect the limits and provide access controls over that data, users will be able to access personalized services which will understand and use their personal data.

Identity 2.0 may seem like some geeky, visionary future standard that isn't defined yet, but by putting each user's digital identity at the core of all their online experiences, Identity 2.0 is becoming the cornerstone of the new open web.

The Initiatives: Right now, Identity 2.0 is under construction through various efforts from Microsoft (the "InfoCard" component built into the Vista operating system and its "Identity Metasystem"), Sxip Identity, Identity Commons, Liberty Alliance, LID (NetMesh's Lightweight ID), and SixApart's OpenID.
