Is Digital Identity just for provisioning and SSO?
No. Definitely not.
These days, however, it looks like that when people talk about DI, it is directory server, provisioning, SSO. This is not right, but even in DIDW, it seems it was the way DI was presented.
My idea of Digital Identity is quite different. Digital Idenitity is the projection (mapping) of the real world objects including human being to the digital world, and defining the method to identify them and the interaction. Ajay, with whom I met today, shared this view.
Perhaps it is the time that we should find a fresh word for this concept.
