Abstract

This talk is about putting the human in the loop, or rather making sure that there is a human in the loop. Sometimes we have this feeling that, while we’re still responsible for what the computer does, we don’t have control over what it does, and it would be nice to make sure that at least some human has seen what goes on. So this is about countering automated exploits with system security CAPTCHAs, I know it is a bad idea to have an acronym in the title but I was at Microsoft Research when we did this work. CAPTCHA for those of you who don’t know, it is a Completely Automated Public Turing Test to Tell Computers and Humans Apart.
