Question

The protection systems involve some unique aspect of a person's body is :

• A. Authorization
• B. Biometric
• C. Authentication
• D. None of these

Answer 1

Answer:

B. Biometric

• Biometric protection systems are security technologies that use unique physical or behavioral characteristics of a person's body for identification and authentication purposes. These systems rely on distinctive biological features that are virtually impossible to replicate or forge.

• The key aspects of biometric protection systems include:

  1. Uniqueness: Every individual has distinct biological characteristics such as fingerprints, iris patterns, facial features, voice patterns, and DNA.

  2. Permanence: These biological traits remain relatively stable throughout a person's lifetime, making them reliable for long-term identification.

  3. Measurability: These characteristics can be captured, processed, and stored digitally for comparison purposes.

• Common types of biometric systems include:

  • Fingerprint recognition

  • Iris scanning

  • Facial recognition

  • Voice recognition

  • Retinal scanning

  • Hand geometry

  • DNA analysis

• Biometric systems offer several advantages over traditional security methods like passwords or ID cards:

  • Cannot be forgotten or lost

  • Difficult to duplicate or steal

  • Provide higher security levels

  • User-friendly and convenient

• In contrast, the other options are not correct:

  • Authorization refers to granting permissions or access rights

  • Authentication is the process of verifying identity (which biometrics can be used for, but it's not the system itself)

  • "None of these" is incorrect as biometric is indeed the right answer

• Therefore, biometric protection systems are the security technologies that involve unique aspects of a person's body for identification and protection purposes.
