Does anyone know the name of this TED Talk, or the speaker?

I watched a TED Talk yesterday in which the speaker talked about universal data access and how it was changing the face of business. He used the Encyclopedia evolving into Wikipedia as one example. He also talked about N.O.R.A,. (Non-Obvious Relationship Awareness) software and how it is used in Casinos to spot cheaters. I can not find that talk again. Does anyone remember the talk, the name of the talk, or the speaker?
