TuringTest

Are you a human or a computer?

It is useful to distinguesh a human from a computer to prevent automated attacks on web systems. In this version of the Turing test we are only interested in whether you are a person or not, independent of your intelligence.

Many sites show a distorted image of a password for you to key in to prove you are not a computer. We will need to do something like that to prevent automated attacks on WikiWorld before we can reenable anonymous editing and self registration.

The idea here of sharing trust is a great idea WE should entertain.

And individualized Turing test authentication is a great concept.
