Elie Bursztein : 2010 Security Workshop

Every web service rely today on CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) to tell efficiently apart human from computers. If the importance of designing good CAPTCHA is commonly acknowledge very little research has been done so far on how to design tests that are easy for human and hard for computers.

In this talk I will present our research result on how to design CAPTCHA that are easy for human and what we have identified as hard for computer.
