Thanks to CTOnews.com netizen OC_Formula for the clue delivery! CTOnews.com, August 13 (Xinhua)-- Robots are better at passing robot tests than humans, according to a new study that refers to more than 200 popular website security systems. However, the study has not yet been peer-reviewed and is currently only published on arXiv.

Robots pose a major threat to the Internet because they can pretend to be legitimate users to carry out operations that endanger the harmonious environment of the Internet, such as grabbing content, creating accounts, publishing false comments or comments, and consuming scarce resources.

Scientists, including scientists at the University of California, Irvine, pointed out that "if unregulated, robots can perform these malicious operations on a large scale."

In the more than 20 years since the birth of CAPTCHA, most websites have deployed it as a security check strategy to stop potentially harmful robots through puzzles that should be very simple for humans but very difficult for computers.

CTOnews.com noted that early CAPTCHA required users to recognize and retell text from distorted images, but with advances in computer vision and machine learning technology, robots successfully recognized the text with near-perfect accuracy in a short period of time, faster and more accurate.

Subsequently, humans began an arms race with robots in the field of CAPTCHA. As a result, CAPTCHA is becoming more and more troublesome and annoying, even for humans and robots.

In the study, scientists tested 200 of the most popular websites and found that 120 of them still use traditional CAPTCHA mechanisms.

With the help of 1000 participants from different backgrounds (location, age, gender and education level), they conducted 10 CAPTCHA tests on these sites to assess their difficulty.

Researchers have found that robots described in many scientific journals can outperform humans in terms of speed and accuracy.

For example, some CAPTCHA tests may take 9 to 15 seconds to be identified by human participants, with an accuracy of about 50% to 84%, while robots can crack them in less than a second, and the accuracy is almost perfect.

"the accuracy of robots ranges from 85 to 100%, with most of them exceeding 96%. This greatly exceeds the range of human accuracy we have observed (50-85%)," the scientists wrote in the study.

They also found that in all cases, robots took "significantly less" or almost the same time to solve problems as humans.
