Video CAPTCHAs
I completed my MS thesis at the Rochester Institute of Technology’s Department of Computer Science in Document and Pattern Recognition Lab under the advisement of Dr. Richard Zanibbi from Sept 2007 to August 2008. In this time, a video-based CAPTCHA using YouTube.com videos was developed. A user is presented with a video which they must correctly tag. For a live demo, please click here.

Although I didn’t blog nearly as much as I had hoped about the experience, several posts about my thesis can be found in the thesis category.
