Around the world, artificial intelligence （AI） has slowly become a part of our everyday lives. One of the biggest implementations （实施） is facial recognition （FR） technology.
After enabling people to make payments, FR has now been put to use in the subway of Zhengzhou, Henan province.in September, FR is available to passenger who link their online payment systems to the smartphone app of the subway. China Daily reports that other cities in China,Beijing, are testing a similar system.
It's not hard to set why FR technology could help speed up security checks meaningfully. Yuan Xiaoqin, a park manager in Hangzhou, told China Central Television the reason the park changedentry system: "Facial recognition can help a visitor enter the park in two or three seconds. Fingerprint information sometimes isn't sensitive （灵敏的）,in cases of being hurt or when the fingers are too dry to be recognized. " Before, the park used a fingerprint entry system.
However, the use of facial recognition some problems about security hidden danger so far.
Many people feel using facial recognition. They doubt the necessity of using facial details and worry the information could be let out. Their worries are . In August, a face— changing app called Zao allowed users to imitate （模仿） famous stars from films and TV through the use of facial recognition.as it was, users worried that the app was collecting a large amount of personal information.
Sometimes people can refuse the app if they don't want their facial information disclosed, but sometimes people don't have a choice. Once this information is let out, it's hard to take useful actions. There is no law in China the use and collection of facial information. App operators, public service and government departments should be more careful in preventing use of the technology disorderly.
