The U.S. has the largest number of surveillance cameras per person in the world. Cameras are omnipresent on city streets and in hotels, restaurants, malls and offices. They’re also used to screen passengers for the Transportation Security Administration. And then there are smart doorbells and other home security cameras.
Most Americans are aware of video surveillance of public spaces. Likewise, most people know about online tracking – and want Congress to do something about it. But as a researcher who studies digital culture and secret communications, I believe that to understand how pervasive surveillance is, it’s important to recognize how physical and digital tracking work together.
