Luis von Ahn pioneered CAPTCHA, the technology for those scrambled, wavy-looking codes that hundreds of thousands of humans type in for online security. A professor in the Computer Science Department at Carnegie Mellon University, Dr. von Ahn is an expert on crowd sourcing, or Human Computation, and will speak on "The Computational Power of Humans and Computers" and explain what those CAPTCHAs are really about.
