2 . It’s well-known that facial recognition is widely used in shopping, home security, and law enforcement and millions of us use it to open our smartphones. But privacy advocates are raising alarms about the growing use of facial recognition technology.

The American administration recently proposed a rule to use facial recognition to identify and photograph all people entering and leaving the United States, including American citizens. That idea was scrapped after big objections from lawmakers and activists, but the administration is moving ahead with more limited use of the technology in a number of airports and other ports of entry say it makes the public safer and so far, they’ve had very few complaints from travelers.

However, a growing number of, both in and out of the government, say any type of facial recognition is just like illegal surveillance (监视). They say it exchanges too much freedom for too little security. Many note that once the government has a database of Americans with their photographs, there’s no telling what it could be used for. Beyond the privacy concerns, security experts are also worried that a huge government database could be a major target for a data breach (数据泄露). Some say it could give hackers access to data from millions of Americans.

Mike Howell, a former consultant of the Department of Homeland Security, suggests a possible solution: simply erase the information after it used. “The big question for,” says Howell, “is how the government largely will protect the data. We want the data we collect to keep us safe from threats, not to, you know, make unsafe. “Finally, the administration may have the final say on the future of facial recognition, with more regulations being advised to keep it in check.”
