问题     State and local authorities from New Hampshire to San Francisco have begun banning the use of facial-recognition technology. Their suspicion is well【C1】________: these algorithms make lots of mistakes, particularly when it【C2】________identifying women and people of color. Even if the tech gets more accurate, facial recognition will unleash an invasion of privacy that could make anonymity impossible.【C3】________, bans on its use by local governments have done little to curb adoption by businesses from startups to large corporations.
    Automated face-recognition programs do have advantages, 【C4】________their ability to turn a person’s unique appearance into a biometric ID that can let phone users【C5】________ their devices with a glance. To train such systems, researchers【C6】________a variety of photographs to a machine-learning algorithm. The more data they【C7】________, the more【C8】________these programs become.
    Too often,【C9】________, the algorithms are deployed prematurely. In London, for example,  police have begun using artificial-intelligence systems to scan surveillance footage in an attempt to【C10】________wanted criminals as they walk by—despite an independent review that found this system labeled suspects【C11】________only 19 percent of the time.

Google contractors in Atlanta, for example, have been accused of exploiting homeless black people in the company’s quest for faces, buying their images for a few dollars. Such stories suggest that some companies are tackling this problem as an afterthought【C16】________addressing it responsibly.
    Even if someone releases improved facial-recognition software【C17】________high accuracy across every demographic, this technology will still be a【C18】________Because algorithms can scan video footage much more quickly than humans can, facial recognition【C19】________constant surveillance of a population. These systems can easily be used to treat every citizen like a criminal, which destroys individual privacy,【C20】________free expression and causes psychological damage.
