What act involves pretending to be another user to bypass a biometric-based authentication system?

The act of pretending to be another user to bypass a biometric-based authentication system is known as biometric impersonation. This typically involves using some form of replication or mimicry of biometric characteristics, such as fingerprints, facial recognition, or iris patterns, to falsely authenticate oneself as the authorized user.

Biometric authentication systems are intended to provide a high level of security based on unique physical traits, but they can be susceptible to sophisticated attacks where an attacker might use a fake fingerprint mold or a high-resolution image of someone's face to fool the system.

Biometric impersonation specifically targets these systems to gain unauthorized access, making it a distinct threat in the realm of cybersecurity and personal information protection. It emphasizes the importance of not only having biometric systems in place but also incorporating additional layers of security to validate identity beyond just one biometric factor.
