Security company strengthens CAPTCHAs with video
A security company called NuCaptcha is incorporating advertising into a video CAPTCHA system that is much harder for computers to break.
CATPCHA stands for “Completely Automated Public Turing Test to Tell Computers and Humans Apart.” It was developed to thwart Web annoyances such as spam and false account registrations, among others. It uses a box of jumbled letters that humans must decode to allow, for example, a registration to proceed.
When CAPTCHAs were first introduced, it was difficult for optical character recognition (OCR) technologies to break them. Over the last few years, that has changed, and CAPTCHAs are much less effective.
In order to halt automated CAPTCHA solving programs, the puzzles have been made more difficult to solve, so much so that many are nearly unreadable to humans as well.
“The bottom line is that the static image CAPTCHA technology that dominates the Web today is simply maxed out,” said Michel Giasson, CEO and founder of NuCaptcha.
