The correct answer is A. Biometrics.
Biometrics is the measurement of physical or behavioral characteristics of individuals to establish a unique identity. It is used in a variety of applications, including security access, law enforcement, and healthcare.
Biometric measurements can be divided into two categories: physiological and behavioral. Physiological biometrics include characteristics such as fingerprints, facial recognition, and retinal scans. Behavioral biometrics include characteristics such as voice recognition and typing patterns.
Biometrics is a reliable and accurate way to identify individuals. It is also difficult to forge or counterfeit biometric data. As a result, biometrics is increasingly being used in security applications, such as access control and fraud detection.
Here is a brief explanation of each option:
- Biomeasurement is the measurement of biological processes or functions. It is used in a variety of applications, including medical diagnosis, research, and sports performance.
- Computer security is the protection of computer systems and networks from unauthorized access, use, disclosure, disruption, modification, or destruction. It is a broad field that encompasses a variety of security measures, such as firewalls, intrusion detection systems, and data encryption.
- Smart weapon machinery is a type of weapon that uses artificial intelligence to make decisions about when and how to fire. It is a controversial technology that raises concerns about the potential for misuse.
