An organization is developing an authentication service for use at the entry and exit ports of country borders. The service will
use data feeds obtained from passport systems, passenger manifests, and high-definition video feeds from CCTV systems that are located at the ports. The service will incorporate machine- learning techniques to eliminate biometric enrollment processes while still allowing authorities to identify passengers with increasing accuracy over time. The more frequently passengers travel, the more accurately the service will identify them. Which of the following biometrics will MOST likely be used, without the need for enrollment? a. Voice
b. Gait
c. Vein
d. Facial
e. Retina
f. Fingerprint
A face recognition system is a computer program for identifying people from photos or videos. Face recognition is performed according to the geometric characteristics of the face and is compared with a database. It is also possible to determine the sex and estimate the age of persons. The main advantage of these systems is that the people who are going to be recognized by it do not need to enroll or provide their data on some previous basis, but, on the contrary, this system can extract images even without the consent of those investigated .
