Identity basics – The Identity Quartet

Last week I attended the VRM West Coast Workshop and one of the many impressive folks I met there was Joe Andrieu of Switchbook. In a recent blog post, Joe describes the The Identity Quartet – the key services that allow user to express their identity in online services. It’s one of the most clear descriptions of the identifier issues I’ve read. Joe even makes the point:

The Identity Quartet pattern isn’t rocket science. In fact, it makes things simpler when it comes to security, maintenance, and user control. The Quartet makes systems more flexible and more secure while giving users more freedom to manage how they interact and present themselves online. It is one way to turn user-centric Identity services of OpenID and Information Cards into truly user-driven Identity.
