Friendly Captcha
This script initializes and manages a captcha challenge designed to verify human users and prevent automated bot access to website resources. Unlike traditional image-based captchas, Friendly Captcha typically employs a non-intrusive, proof-of-work mechanism that runs in the background. It analyzes environmental factors and computational capabilities of the client browser to differentiate between human users and bots, without requiring explicit user interaction such as clicking images or solving puzzles. The script operates client-side, communicating with Friendly Captcha's backend services to validate challenge solutions. It is designed to be privacy-friendly, minimizing data collection and avoiding persistent tracking cookies, making it a GDPR-compliant solution for securing forms, logins, and other sensitive areas against spam, credential stuffing, and other malicious automated activities.
