Abstract

A lan Turing's " imitation game, " defined in his classic 1950 paper " Computing Machinery and Intelligence, " proposed a method of testing for intelligence based on a dialogue over teletype machines. The Turing Test, as it has come to be called, posed the question: could a computer fool humans into thinking that they were talking to one of their own? If so, then the computer, Turing declared, had intelligence. Although the Turing Test is still considered a radical " definition " of artificial intelligence 50 years after its introduction, it turns out that we need this test. You see, there are currently artificially intelligent creatures among us, and they want to sell us stuff! Let me explain. As you may know, " chat rooms " are virtual places accessed by programs for use by people who want to type messages to each other in real time. Many people meet in these chat rooms to discuss the important events of the day, for example , when will the sequel to the Matrix will be released, or more importantly, who will star in Matrix III. Some programmers have built " chat robots " that enter these chat rooms disguised as humans and either simply spew out advertisements, or wait patiently, and then spew out advertisements. The problem is that one can't tell by looking at a handle (i.e., a screen name) that a user is in fact not human. A typical chat room conversation might look like: neo23: so, have you seen the trailer yet? neo45: no, but I bet it's gonna b kewl :) neo67: Visit www.X.com for $50 off of a pair of swim trunks, while supplies last. Now, the normal user wouldn't be able to tell that neo67 was in fact a adbot until it was too late: They have already advertised (some may still not be convinced that this user is not human but I assure you, no one would say such things in a chat room). Detecting adbots might not be seen as a pressing problem, until you are bombarded with 1 million advertisements at once. This does slow down communication about the Matrix, and other topics I suspect. How can we detect these insidious adbots before they do their dirty deeds? Enter The CAPTCHA Bongo Project. The CAPTCHA Bongo Project is a project of the School of Computer Science at Carnegie Mellon University. Their …
