We were very happy to hear that our Usenix Security’12 paper, “Security and Usability Challenges of Moving-Object CAPTCHAs: Decoding Codewords in Motion”, has been accepted. The paper was a joint effort with Yi Xu, Jan-Michael Frahm, and Fabian Monrose from the University of North Carolina. On the Carleton side, Gerardo Reynaga, Paul van Oorschot, and I worked on the project. A copy of the paper will be available shortly.
