reCAPTCHA Inc. is a corporation that produces CAPTCHA systems, which help websites distinguish between human users and automated bots. It is owned by Google, its parent company. The original version of reCAPTCHA asked users to decipher hard-to-read text or match images. Version 2 also asked users to decipher text or match images if the analysis of cookies and canvas rendering suggested the page was being downloaded automatically. Since version 3, reCAPTCHA will never interrupt users and is intended to run automatically when users load pages or click buttons.
