CAPTCHA and HIP are tests performed by a web service to
distinguish between computers and humans.
One example use of this technology is to prevent spammers from writing automated scripts to spam you
through services like Hotmail and
GMail.

Artificial Intelligence has progressed to the point that in
some instances, computers are better than humans
at passing CAPTCHAs and HIPs! As a result, CAPTCHAs end up hindering systems instead of strengthening
and protecting them.

The Warhol Proof is a second-generation proof designed to provide viable CAPTCHA/HIP services for several
years to come. It relies heavily upon obfuscated visual images whose interpretation requires gestalt
perception and other innately human abilities.
