Cloudflare Turnstile the successor to CAPTCHA

Cloudflare he said this week an ambitious new project called Turnstile, which seeks to replace the CAPTCHAs used across the web for verification.

It will be available to all sites free of charge, Cloudflare customers or not. Turnstile will give you the option to choose from a rotating suite of “program challenges ” to check whether visitors to a website are humans or bots.

CAPTCHAs, the challenge-response tests we all encounter when filling out forms, have been around for decades. But the rise of cheap labor, CAPTCHA bugs and automated solvers have begun to poke holes in the system.

Several websites offer human and AI-powered CAPTCHA solving services for as little as $0,50 per thousand CAPTCHAs solved, and some researchers claim that attacks using AI can solve CAPTCHAs used by the world's most popular websites.

For those who remember Cloudflare used to use CAPTCHA too. But according to CTO John Graham-Cumming, the company was never quite satisfied with that. In one that he had with TechCrunch, Graham-Cumming listed many of its drawbacks CAPTCHAs, such as accessibility (some disabilities may make it impossible to solve a CAPTCHA), culturality (CAPTCHAs require familiarity with objects such as US taxis), and the problems CAPTCHAs cause on mobile data plans.

Turnstile automatically selects a challenge for the με βάση την “τηλεμετρία και τη συμπεριφορά που έχει ο χρήστης κατά τη διάρκεια μιας συνεδρίας”. Η Cloudflare αναφέρει ότι δεν χρησιμοποιεί άλλους παράγοντες όπως τα connection.

After running non-interactive JavaScript challenges to collect signals about the visitor and the browser environment and using artificial intelligence models to identify characteristics of visitors who have passed a challenge in the past, Turnstile adjusts the difficulty of the challenge to the request.
