How can biometric authentication deter unauthorized access to copyrighted content?

Biometric authentication systems can reduce unauthorized access to copyrighted material by uniquely identifying individuals based on their physiological or behavioral traits such as fingerprints, facial recognition, iris scans, voice recognition, or hand geometry. By requiring biometric authentication to access copyrighted material, it can prevent unauthorized users from gaining entry, as biometric data is difficult to replicate or steal compared to traditional passwords or PINs. This adds an extra layer of security, making it more challenging for unauthorized users to breach the system and access copyrighted material.
