Facial recognition technology(人脸识别技术）is widely used today. For example, police use it to search for bad guys. It's also used to unlock phones or doors.

Now, a similar technology, known as facial detection(探测), is entering a new field: the business of advertising(广告).

Such systems are going through tests in a small number of stores. One facial detection system can judge a person's "happiness" or "fear" level. That helps businesses see how people feel as they lo at products or advertisements in the store. Another system can detect whether someone is wearing eyeglasses. If so, stores can send advertisements for new glasses to him.

Facial detection technology is also placed inside some large advertising boards. Cameras in those boards can detect information like people's ages and five levels of feelings——from "very happy" to "very unhappy".

Supporters of the technology say it could improve buyers' experience by showing products they might like or by offering them products at lower prices.

Some are against the idea of using such systems. Pam Dixon, the head of a privacy(隐私)group, is one of them. She thinks 　　 ▲　　 . For example, a business could raise the price of a product according to a person's age and feelings.

However, one store testing the technology explained they wouldn't store people's information like names or ages. And the advertising board system maker said it didn't keep any personal information or record any videos.

Around the world,facial recognition（FR人脸识别）has slowly become a part of our daily life.

After helping people to make payments and open bank accounts,FR now is used in the subway of Zhengzhou,Henan Province. FR was introduced in September and now it can be used by passengers who link their online payment systems to the subway's smartphone app. China Daily reports that other cities in China,including Beijing,are testing a similar system.

It's not hard to see why. FR technology could help speed up security （安全） checks greatly. Yuan Xiaoqin,a park manager in Hangzhou,told CCTV the reason why the park upgraded （升级） its entry system,"FR can help a visitor enter the park in two or three seconds. Fingerprint information sometimes isn't sensitive （灵敏的）,especially when the fingers are injured or too dry." Before,the park used a fingerprint entry system.

However,there are some problems with the use of FR. Some people are afraid that their personal information will be leaked.

In fact,sometimes people can refuse the app if they don't want their facial information disclosed （暴露）,but sometimes people don't have a choice.

From China to the United States, facial recognition technology is being used and tested like this at the Los Angeles International Airport. This pilot program that takes a picture of the passenger and compares it to the passport picture, is just one way facial recognition technology can be used for safety. The facial recognition technology can also be used for surveillance（监视）and for the commercial use（商业用途）.

Great achievements have been made in facial recognition technology in recent years.

The technology is used to identify a missing child. Computers are finally fast enough to process all the data that we need to process. Machines can now match faces even when the lighting isn't good or when a full shot of the face is not available. a side shot or moving image of the face may be enough for artificial intelligence to make a match.

Face first is one of many companies developing facial recognition software with endless possible uses. Try to imagine that everyday items that we have such as our house keys, our car keys, our ATM cards, our passwords are all starting to go away and instead, We’re going to be using facial recognition, Smart phones, of course are now using facial recognition. Laptops have facial recognition on them.

The ability to get an image of a person without permission comes with privacy worries.

“My biggest worry is actually not the government, it’s the big companies where there are really no limits on how they can share data, what they can use it for, how they can use it.”

Facial recognition researchers say some social rules should be created to guide the use of this technology, so it can be used safely to do good to society.

It's reported that a Chinese company has created a new facial recognition system that can identify (识别) people even if they are wearing masks. Developers began working on the new system in January 2020 when the novel coronavirus appeared in China. The fast spread of the virus has led most people to wear masks in public to protect themselves and people around.

China is regarded as a world leader in the development of artificial intelligence (AI). According to engineers at the Beijing——based Hanwang Technology Ltd, this system is the first to be created to identify people wearing face masks. A team of 20 engineers completed it in about a month, adding a collection of about 6 million unmasked faces and a smaller collection of masked faces," the company said.

Hanwang is now selling two main kinds of products using the new technology. One performs single channel recognition (单通道识别), which will be used at the entrances to buildings. The other product is a multi—channel (多通道识别) recognition system that uses groups of cameras. It's said thatthe multi—channel system can identify a person in a crowd of up to 30 people within a second.

When people wear a mask, the recognition rate　 can reach about 95 percent," said Huang Lei, Hanwang's vice president. The system's success rate for people without wearing a mask is about 99. 5 percent."

Nowadays the new system is trying to identify people with both sunglasses and a mask. In such cases, all of the key facial information is lost, making recognition hard," Huang said.

A.The truth that people should wear masks in public.

B.The reason why a new facial recognition system was created.
