It's quite telling that a discussion thread dedicated to criticism ended up to be purely about the name.
And that's because that's the case really - everything is solid and flawless except the name.
I think to myself: what a shame such a great idea is going to be wasted for such trivial reason.
So please John don't kill your brilliant child with an ill-chosen name. It will come and haunt you when you try to promote it. People are mostly irrational and the name will distract them from the concept itself.
What I already proposed in the other thread is this: IDENTICON. It's not perfect but the best I can come up with if we need to have the word "identity" embedded in it.
Or it can even be Pied Piper
