CAPTCHA is a challenge-response exercise that is designed to differentiate between humans and bots, and to prevent unauthorized access to websites. The fact that the user is prompted to provide extra information indicates that the website is implementing a form of CAPTCHA. Symmetric encryption involves the use of a single key to encrypt and decrypt data, while asymmetric encryption involves the use of a public and private key. Biometric authentication uses physical characteristics such as fingerprints, facial recognition, and voice recognition to verify a user's identity.
