3D-Based CAPTCHAs Become a Reality
mateuscb writes "A new way of creating a CAPTCHA using 3D objects has become a reality. The idea was thought up independently by blogger Taylor Hayward and by the folks at YUNiTi.com. 'Similar to Hayward's idea, this new technology relies on our ability to identify objects in 3D instead of using alphanumeric characters. YUNiti's 3D Captcha, however, has three objects in the challenge and extends the list of images to any object, not limiting it to animals as in Hayward's idea. This increases the challenge's level of complication to prevent computers from successfully making the correct guesses.' I, for one, welcome the thought of not having to read more and more complex CAPTCHA. Lately, I've been having a hard time getting CAPTCHA to work the first time."
It's much worse than that. Put up a porn site. Use free content. Have a "Solve captcha to get free pics!" blocker.
Now, grab a captcha you want to break, show to pornaholics, get solution, pass it back to the original site.
Perfectly unbeatable captcha solving, for virtually free, and totally automated.
Feh.
