How Does Google reCAPTCHA Work?

At its core, Google reCAPTCHA operates by analyzing user behavior and interactions to determine whether they are human or a bot. It uses advanced algorithms and machine learning to assess the risk level of each interaction. If the system identifies suspicious activity, it prompts the user to complete a challenge.

Steps Involved in Google reCAPTCHA Verification
