Google reCAPTCHA vs. GDPR: Privacy Risks and Solutions

Google's reCAPTCHA technology, used to identify website visitors as human, clashes with the GDPR. reCAPTCHA analyzes user behavior (mouse movements, keystrokes, etc.) and collects personal data like IP addresses and browser information to assess user identity.

The article recommends using more privacy-friendly alternatives and emphasizes transparency, obtaining user consent, and data minimization.
