We, for one, welcome our distorted-letter-recognizing overlords
They then compared their successes to those of a number of bots coded by researchers and published in journals for the purpose of beating CAPTCHA tests. The results make for embarrassing reading.
For distorted text fields, humans took 9-15 seconds with an accuracy of just 50-84 percent. Bots, on the other hand, beat the tests in less than a second with 99.8 percent accuracy. "There's no easy way using these little image challenges or whatever to distinguish between a human and a bot any more," commented team member Andrew Searles, recommending that organizations should use"intelligent algorithms" to sort bot interactions from legit ones rather than CAPTCHA.Shujun Li, professor of cyber security at the University of Kent, explained that the explosion in advanced machine learning methods have rendered the defense obsolete.
"In general, as a concept CAPTCHA has not met the security goal, and currently is more an inconvenience for less determined attackers," he said."New approaches are needed, like more dynamic approaches using behavioural analysis." Jess Leroy, senior director of product management at Google Cloud, added:"We are increasingly focused on recognizing and interrupting malicious activity, whether perpetrated by bots or humans. As such, we are able to help our customers prevent loss even as AI bots become better at masquerading as humans. Further, we have a very large focus on helping our customers protect their users without showing visual challenges, which is why we launched reCAPTCHA v3 in 2018.
