Ars Technica reports that audio CAPTCHAs consisting of only distorted digits or letters can be easy to crack using machine learning techniques. This includes most of the audio CAPTCHAs currently in use on the Web. The reCAPTCHA team has discussed their new audio CAPTCHA, which is resistant to this attack.

Luis von Ahn and his team at Carnegie Mellon University have launched GWAP, a new web site for "Games With A Purpose". By playing these online games, humans help provide data for problems that are hard for computers to solve, such as computer vision and sound classification. AP and the BBC have reported on the launch. Slashdot has previously covered other human computation projects by Dr. von Ahn, including the ESP Game and reCAPTCHA. The new web site contains a re-vamping of the ESP Game as well as four completely new games.
