Researchers Break Video CAPTCHAs 109
Orome1 writes "After creating the 'Decaptcha' software to solve audio CAPTCHAs, Stanford University's researchers modified it and turned it against text and, quite recently, video CAPTCHAs with considerable success. Video CAPTCHAs have been touted by their developer, NuCaptcha, as the best and most secure method of spotting bots trying to pass themselves off as human users. Unfortunately for the company, researchers have managed to prove that over 90 percent of the company's video CAPTCHAs can be decoded by using their Decaptcha software in conjunction with optical flow algorithms created by researchers in the computer vision field of study."

It's fun to observe it when government does not interfere.

The catchpa is worthless against an army of Indians being paid just pennies a pop to break them. The only thing they do is annoy the script kiddies. Far better success would be had in doing pattern recognition on sign ups instead.

No, They also annoy your actual, real human users. I often have to try three or four times to get the bloody thing right.
