Identify one limitation of biometric access control in EAC systems.

Biometric access control systems utilize unique physical characteristics of individuals, such as fingerprints, facial recognition, or iris patterns, to grant access. However, one significant limitation is that biometric data can be subject to spoofing or duplication. This means that an unauthorized individual could potentially replicate or mimic a biometric trait, thereby gaining unauthorized access to a system. For instance, with advanced technology, techniques such as silicone fingerprints or photo re-creations for facial recognition can compromise the integrity of biometric security measures.

This vulnerability underscores the necessity for robust security protocols and supplementary measures, such as multi-factor authentication, to enhance overall access control systems. While other aspects of biometric access control may present challenges, the susceptibility to spoofing is particularly noteworthy as it directly affects the reliability and trustworthiness of the system in securing sensitive areas or information.
