Hi, This is the presentation which was delivered on Drag and Drop CAPTCHA, in IEEE International Conference Indicon 2009.
http://ewh.ieee.org/r10/gujarat/indicon2009/index.html
This paper basically displays new approach to CAPTCHA and avoid possible threats against the laundry attacks and OCRs.
You can find the Research Paper of IEEE at IEEE Xplore.

12. ( FROM WWW.SLASHDOT.ORG) QUICKVOTE Which is the best Computer Science Grad School in the US? CMU MIT vote Berkeley Stanford Cornell Washington ONLINE POLLS
35. CAPTCHA SWEAT SHOPS SPAM COMPANIES HIRE HUMANS TO SOLVE CAPTCHAS ALL DAY LONG $2.50 PER HOUR FOR EACH HUMAN 720 CAPTCHAS PER HOUR PER HUMAN 1/3 CENT PER ACCOUNT LAUNDRY ATTACKS

This is a CAPTCHA…….U must b familiar with this image with many sign up forms.

In simplest form …….
WHY DO WE HAVE TO PASS A TEST TO PROVE WE ARE HUMANS? LETS HAVE A CASE STUDY.
Here public means that the code and the data used by a CAPTCHA should be publicly available. This is not an open source requirement, but a security guarantee. It should be difficult for someone to write a computer program that can pass the tests generated by a CAPTCHA even if they know exactly how the CAPTCHA works (the only hidden information is a small amount of randomness utilized to generate the tests).

THIS IS A SCREEN SHOT OF ONLINE POLLING. IT WAS CONDUCTED WHEN THERE WEREN’T ANY KIND OF CAPTCHA AVAILIABLE. THE FIGURES WERE ASTONISHING
THE RESULTS OF THE POLL WERE ASTONISHING! CMU AND MIT GOT ABOUT MORE THAN 20000 VOTES WHILE REST COULD NOT EVEN GET PAST 1500. HOW WAS THAT POSSIBLE?? THANKS TO BOTS AND SPIDERS????XPLAIN BOTS AND SPIDERS IN BRIEF
