The NIST guidelines break up digital identity management into three sections: enrollment and identity proofing, authentication and life cycle management and .

If that breakdown sounds familiar to blog readers, it’s because it is congruent with the “Three Domain Identity” (3DID) model that we developed a few years ago to help our clients to formulate strategies around digital identity. Just as a reminder, the three domains in our model are “identification” (NIST’s enrollment, identity proofing), “authentication” (NIST’s authentication and life cycle management), and “authorisation” (NIST’s federation and assertions). I made a handy “cut out n’ keep” graphic.

So, it seems to me that the 3DID model provides an excellent basis for government and business to establish a shared digital identity paradigm.
