China is recognized as a world leader in the development of artificial intelligence and facial recognition systems. A Chinese company says it has created a new facial recognition system that can identify people even if they are wearing masks. Engineers at the Beijing-based company say their system is the first to be created to effectively identify people wearing face masks.
The company told a news agency that a team of 20 people built the system in about a month. The system is based on existing technologies developed over the past 10 years. The process involved adding a collection of about 6 million unmasked faces and a much smaller collection of masked faces, the company said.
The company is now selling two main kinds of products that use the new technology. One performs "single channel" recognition, which is designed to be used at the entrances to buildings.
The other product is a "multi-channel" recognition system that uses groups of surveillance cameras. It can identify individuals in a crowd of up to 30 people "within a second.
"When people are wearing a mask that covers the mouth and the nose, the recognition rate can reach about 95%, which can ensure that most people can be identified," said Huang, vice president of the company. He added that the system's success rate for people not wearing a mask is about 99.5%.
However, the new system struggles to identify people wearing both a mask and sunglasses. "In this situation, all of the key facial information is lost. In such cases recognition is tough," Huang said.
People were reacting differently to the new technology. While some citizens have been against using such tools, the majority have accepted the technology as an effective way to decrease crime and catch criminals.
1.What did the company do to build the system?
A.They gathered many face images.
B.They employed hundreds of people.

D.They spent about a decade building it.
2.According to the passage, which of the following can be true?
A.The new system has already been used by the police.
B.The recognition rate of masked faces is about 99.5%.
C.It's hard to recognize people with masks and sunglasses.
D.The single channel product is as powerful as the multi-channel.
3.Which of the key facial information might have the biggest impact on recognition rate?
A.One's eyes. B.One's nose.
C.One's mouth. D.One's hair.
4.What is the main purpose of the text?
A.To show conflicting attitudes toward the system.
B.To introduce a new facial recognition system.
C.To advertise two products of facial recognition.
D.To show the advantages of facial recognition.
