Jason Polakis, a professor in computer science, took credit for an increase in CAPTCHA difficulty in 2016 when he published a paper where he used image recognition tools to solve Google image CAPTCHAs with an accuracy of 70%. Polakis believes we are at a point at which making CAPTCHAs harde...
Math CAPTCHAs present an equation for the user to solve. For example, an image displays the problem “18 + 5 =?” and asks users to enter the correct answer. The user then types in the number 23 and clicks the button to continue. Math CAPTCHA technologies typically generate a new random...

print("Failed to solve the challenge.") This code is the same as Step 3 up to deobfuscating the challenge script contents. Relevant code snippets are extracted from the deobfuscated script, including the challenge function and the success callback function. ...
Google reCAPTCHA v3 doesn’t ask visitors to solve any captcha challenge. It analyzes user behavior and returns a score. The lower the score, the more likely it is that the visitor is a bot. The higher the score, the more likely it is that the visitor is human. ...
The researchers stated they were able to design a low-cost attack that successfully solved more than 70% of the image reCAPTCHA challenges, and each challenge required an average of only 19 seconds to solve. They also applied the system to the Facebook image captcha and found an accuracy leve...
I want to make captcha images with simple calculations like '3 + 4 = '. This is my config file: return [ 'disable' => env('CAPTCHA_DISABLE', false), 'characters' => ['2', '3', '4', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'j...
