Communities across the world are starting to ban facial recognition technologies. The efforts are well intentioned, but banning facial recognition is the wrong way to fight against modem surveillance(监视). Generally, modern mass surveillance has three broad components: identification, correlation and discrimination.

Facial recognition is a technology that can be used to identify people without their consent. Once we are identified, the data about who we are and what we are doing can be correlated with other data. This might be movement data, which can be used to "follow" us as we move throughout our day. It can be purchasing data, Internet browsing data, or data about who we talk to via email or text. It might be data about our income, ethnicity, lifestyle, profession and interests. There is an entire industry of data brokers who make a living by selling our data without our consent.

It's not just that they know who we are; it's that they correlate what they know about us to create profiles about who we are and what our interests are. The whole purpose of this process is for companies to treat individuals differently. We are shown different ads on the Internet and receive different offers for credit cards. In the future, we might be treated differently when we walk into a store, just as we currently are when we visit websites.

It doesn't matter which technology is used to identify people. What's important is that we can be consistently identified over time. We might be completely anonymous(匿名的)in a system that uses unique cookies to track us as we browse the Internet, but the same process of correlation and discrimination still occurs.

Regulating this system means addressing all three steps of the process. A ban on facial recognition won't make any difference. The problem is that we are being identified without our knowledge or consent, and society needs rules about when that is permissible.

Similarly, we need rules about how our data can be combined with other data, and then bought and sold without our knowledge or consent. The data broker industry is almost entirely unregulated now. Reasonable laws would prevent the worst of their abuses.

Finally, we need better rules about when and how it is permissible for companies to discriminate. Discrimination based on protected characteristics like race and gender is already illegal, but those rules are ineffectual against the current technologies of surveillance and control. When people can be identified and their data correlated at a speed and scale previously unseen, we need new rules.

Today, facial recognition technologies are receiving the force of the tech backlash(抵制)，but focusing on them misses the point. We need to have a serious conversation about all the technologies of identification, correlation and discrimination, and decide how much we want to be spied on and what sorts of influence we want them to have over our lives.
