Biometric authentication
A. only uses biographical details for identification.
B. is used widely in Europe for security applications.
C. can use a person’s voice as a unique, measurable trait.
D. is inexpensive.
The Correct Answer and Explanation is:
The correct answer is C. can use a person’s voice as a unique, measurable trait.
Explanation:
Biometric authentication refers to the process of identifying individuals based on their unique biological traits. This method has gained traction due to its enhanced security capabilities compared to traditional authentication methods like passwords or PINs. Various biometric modalities can be used, including fingerprints, facial recognition, iris patterns, and voice recognition.
Option A, which states that biometric authentication only uses biographical details for identification, is incorrect. Biographical details are typically not unique enough for reliable identification and are not the primary basis for biometric systems. Biometric systems rely on measurable physical or behavioral characteristics.
Option B mentions that biometric authentication is widely used in Europe for security applications, which, while partially true, is not specific enough to be the best answer. Biometric systems are indeed utilized in various regions, including Europe, for security purposes, but their use is global and not limited to this area.
Option D states that biometric authentication is inexpensive. This is misleading because while some biometric systems may be affordable, others can be quite expensive due to the technology involved. High-quality biometric systems often require significant investment in both hardware and software, along with ongoing maintenance costs.
Option C accurately highlights voice recognition as a form of biometric authentication. This modality analyzes the unique features of a person’s voice, such as pitch, tone, and cadence, to verify identity. Voice recognition systems can be integrated into various applications, including phone banking, virtual assistants, and security systems. The distinctive nature of an individual’s voice makes it a viable biometric trait, providing a balance of convenience and security.
Overall, biometric authentication’s reliance on unique biological traits, such as voice, enhances its reliability and effectiveness in identifying individuals.
