    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.
