The correct answer is: C. Facial recognition software.
Facial recognition software is a computer application that can identify or verify a person from a digital image or video frame. It is a form of biometrics, which is the scientific process of identifying people based on their physical or behavioral characteristics.
Facial recognition software works by comparing a person’s facial features to a database of known faces. The software can be used to identify people in a crowd, to verify the identity of a person in a security camera image, or to search for a person in a database.
Biochips are small electronic devices that are implanted in the body. They can be used to store medical information, to track a person’s location, or to control medical devices.
Implant chips are similar to biochips, but they are not implanted in the body. They are typically worn on the body or implanted in a piece of clothing.
Vision chips are electronic devices that are used to process visual information. They are used in a variety of applications, including cameras, security systems, and self-driving cars.
While all of these technologies can be used to help identify people, facial recognition software is the most commonly used technology for this purpose.
