Evolution of the 'Captcha'

FireballX301 writes "The New York Times is running an article about the small word puzzles various sites use in order to defeat automated script registration while still letting humans through. It seems many people can't actually solve them anymore, so new alternatives (image recognition) are being created. This, of course, seems breakable as well — is there a feasible alternative to the captcha, or are we stuck jumping through more and more hoops to register at places?"

have a random or semi random set of field names, with an associated "key" field. Use the key field to retrieve the field names of interest. Also have a "name" and "password" field set up so they are invisible to a normal user.

Block any IP submitting a non-blank "name" or "password" field.
