I'm at the Denver Tech Center attending Digital ID World. I'm speaking this morning on digital identity issues in state government. I'll post the slides from my talk after I'm done (since I won't be sure what's in the talk until then). I'll be blogging the conference as I can. The complete set of posts will be in my ID, Privacy, and Security category.
Coincidentally, Dave McNamee blogs about his work on our authentication projects today.
