reCAPTCHA
An anti-automation verification service offered by Google that distinguishes humans from bots by analyzing user behavioral characteristics such as mouse trajectories and browser fingerprints.
Timeline (last 90 days)
Behavioral verification such as reCAPTCHA and hCaptcha relies on human characteristic signals such as mouse trajectories and browser fingerprints, forcing agents to wait for a human at key checkpoints.
reCAPTCHA was originally developed by Luis von Ahn's team at Carnegie Mellon University; the first generation required users to identify two distorted words, one of which came from text that OCR could not recognize in Google Books scans.
Luis von Ahn founded the language learning platform Duolingo based on the concept of reCAPTCHA.
reCAPTCHA v3 completely eliminated user interaction, instead analyzing user behavior through a risk-scoring system.
Google acquired the reCAPTCHA project and used it to digitize books while simultaneously performing human verification.
In the UP host's demonstration, opening a page with reCAPTCHA V2 slider verification using a regular Google Chrome browser caused verification failure due to being detected as under automated control, whereas using Cloak can bypass this.
The content creator claims that Cloak can cover more than 30 detection vendors and pass mainstream bot detection systems such as Cloudflare's five-second shield and Google reCAPTCHA.
