Description

ALTCHA is a CAPTCHA alternative which uses a proof of work mechanism to protect websites and online services against spam. ALTCHA uses a mechanism of proof-of-work to protect your website, online services, and APIs from spam and unwanted material. Unlike other solutions ALTCHA is open-source, self-hosted and free. It does not require external services and does not use fingerprinting or cookies.

Description

The service effectively distinguishes between automated requests and human interactions, filtering out bots while maintaining fast response times. To enhance its analysis, machine learning models are employed, utilizing extensively curated datasets that reflect many years of experience in safeguarding Yandex web resources, which are continuously refreshed. Instead of relying on pre-made images, the service autonomously creates its own, ensuring that it retains an impressive 85% accuracy in human recognition while complicating the process for bots attempting to solve CAPTCHAs. SmartCaptcha operates within the Yandex Cloud infrastructure, adhering to both international standards and Russian laws concerning information security. By implementing this system, you can add user verification to your website without the need for an “I’m not a robot” checkbox; the invisible CAPTCHA is only triggered for users whose requests appear dubious. Furthermore, the service is capable of generating recognition texts on its own, allowing you to select the desired level of complexity to enhance security. This innovative approach ensures a seamless user experience while effectively defending against automated threats.
