Electronic surveillance

The Real Costs of Cheap Surveillance

Surveillance used to be expensive. Even just a few years ago, tailing a person’s movements around the clock required rotating shifts of personnel devoted full-time to the task. Not any more, though.

Governments can track the movements of massive numbers of people by positioning cameras to read license plates, or by setting up facial recognition systems. Those systems need few people to operate them, automating the collection of information about people’s lives and adding that data to searchable databases. Surveillance has become cheap.

I study the law of identification and privacy, so I pay attention to that trend, and it’s worrying. The data maintained in our individual profiles can be used in making decisions about credit, employment, government benefits and more. What governments and companies think they know about us – whether or not it’s accurate – has real power over our actual lives.
