SilverPush is an Indian startup that’s trying to figure out all the different computing devices you own. It embeds inaudible sounds into the webpages you read and the television commercials you watch. Software secretly embedded in your computers, tablets, and smartphones pick up the signals, and then use cookies to transmit that information back to SilverPush. The result is that the company can track you across your different devices. It can correlate the television commercials you watch with the web searches you make. It can link the things you do on your tablet with the things you do on your work computer.

Your computerized things are talking about you behind your back, and for the most part you can’t stop them—or even learn what they’re saying.

This isn’t new, but it’s getting worse.

Surveillance is the business model of the internet, and the more these companies know about the intimate details of your life, the more they can profit from it. Already there are dozens of companies that secretly spy on you as you browse the internet, connecting your behavior on different sites and using that information to target advertisements. You know it when you search for something like a Hawaiian vacation, and ads for similar vacations follow you around the internet for weeks. Companies like Google and Facebook make an enormous profit connecting the things you write about and are interested in with companies trying to sell you things.

We need to think about the ethics of our surveillance economy

Cross-device tracking is the latest obsession for internet marketers. You probably use multiple internet devices: your computer, your smartphone, your tablet, maybe your internet-enabled television—and, increasingly, “Internet of Things” devices like smart thermostats and appliances. All of these devices are spying on you, but the different spies are largely unaware of each other. Start-up companies like SilverPush, 4Info, Drawbridge, Flurry, and Cross Screen Consultants, as well as the big players like Google, Facebook, and Yahoo, are all experimenting with different technologies to “fix” this problem.

Retailers want this information very much. They want to know whether their television advertising causes people to search for their products on the internet. They want to correlate people’s web searching on their smartphones with their buying behavior on their computers. They want to track people’s locations using the surveillance capabilities of their smartphones, and use that information to send geographically targeted ads to their computers. They want the surveillance data from smart appliances correlated with everything else.

This is where the Internet of Things makes the problem worse. As computers get embedded into more of the objects we live with and use, and permeate more aspects of our lives, more companies want to use them to spy on us without out knowledge or consent.

Technically, of course, we did consent. The license agreement we didn’t read but legally agreed to when we unthinkingly clicked “I agree” on a screen, or opened a package we purchased, gives all of those companies the legal right to conduct all of this surveillance. And the way US privacy law is currently written, they own all of that data and don’t need to allow us to see it.
