1ill Blank question 1/3:
READING PASSAGE 1
Read the passage carefully and answer the questions below.
Paragraph 1: We generally recognize people by their faces, or photos, which are typically unique to individuals. However, this type of identification can be faulty. People's appearance changes, and we do not tend to scrutinize photos very closely. Today, biometric technology is being developed to perfect the process of facial identification. Face recognition technology can scan the face for certain features and measure the distances between different parts of the face. THESE THINGS do not change, so growing a beard or wearing glasses will not fool the scanner. Since it is very difficult to mimic another person's face, this type of identification is quite reliable.
Paragraph 2: Facial recognition presents a risk of invasion of people's privacy. Face scanners can be placed in public places, and people's images can be scanned without their knowledge. This allows their movements to be tracked and can also give criminals information that will help them victimize people.
Paragraph 3: On the other hand, security can be improved by using face scanners in public places.
