Americans are more concerned about their privacy at a time when face recognition is widely used when checking in to airports, checking people living in New York City apartment buildings, for example, and even shoppers in small 24-hour shops. More Americans feel that hiding a person's identity can become a thing of the past. A survey by market research firm Moring Council and Polutico on Wednesday found that popular support for face recognition technology has fallen among registered voters.

According to the poll, 42 percent agreed to use the technology, compared with 49 percent in August 2018. Another poll, conducted last Tuesday by the American Civil Liberties Union in Massachusetts, found that eight in 10 or more voters in that state Support a government bill that regulates facial recognition technology, compared with nearly nine out of every 10 claiming to stop it immediately.

Face recognition, which is used to unlock modern phones, will provide a promising technique for people screening, payment acceptance and other identity verification. It also helps arrest criminals, including suspects filmed stealing personal property or sneaking into a car, says Daniel Castro, vice president of IT and Innovation, a Washington-based think tank.

"If the police refrained in the future and said (sorry), we can not use facial recognition to find the person because of the law, I do not think most people would be happy."

This same technique is used to combat more crimes that occurred long before. On Wednesday, media reported that a non-profit anti-trafficking organization had developed a face-matching tool in online advertising with police evidence to identify child victims of sexual abuse. However, legislators in some cities are unwilling to allow the use of this technique for greater security. In May, San Francisco became the first US city to ban the technology. The other cities that consider the ban are Auckland and Berkeley, as well as Somerville and Massachusetts, where the state legislature is considering a moratorium on the technology, supported by the Civil Liberties Union and others. Techniques that can identify people remotely, through their voices, gestures or other fixed "biometric" features.

Also in May, members of the US House Oversight and Reform Committee, in a rare bipartisan consensus, expressed deep concerns about the technology, which was developed by companies such as Amazon, IBM, Microsoft, . Last August, workers at these companies organized sit-ins or protests against labor contracts signed by their employers with law enforcement and immigration agencies and the Pentagon on the use of the technology. Facial recognition technology played a prominent role in the protests at Amazon and Microsoft. There are currently no federal laws governing how to apply this technology, and it is not clear how many 18,000 police departments are currently using the technology.

On the other hand, this technique is inexpensive, easy to use. In April, the New York Times experimented with visitors to a park in central Manhattan, where the cost of the experiment was less than $ 100, and was able to successfully identify visitors.

"Setting up city-level networks of intelligent surveillance cameras and others means to me to give the whole community full control," says one expert, who preferred not to be named. "This technology enables the government or anyone else to create a permanent and comprehensive record, The target person, his groups, his connections and his movements, but for everyone in the city, not in one day, but at all times.
