Next, don't connect to unprotected wifi networks. First, he suggests, you should disable wifi and Bluetooth when you're not using them. McDonald tells people there are some simple steps they can take to reduce the amount of data they leak. ![]() McDonald says people have two main responses to the project: "This is creepy’ and ‘What should I do about this?’”. The issue, McDonald says, is that most of us don't even realize we're broadcasting personal information. Fairly practical information, you might think. Analytics companies like Euclid and Nomi use what they claim is anonymous data to figure out exactly where customers go and how many customers leave without buying something. ![]() Consumers didn't agree, and Nordstrom ended its experiment. Nordstrom argued it was simply the brick and mortar version of what online retailers do with cookies. In 2012, Nordstrom began tracking the wifi signals emitted from shoppers' phones, to pinpoint their location in the store. “Normally these packets are getting sent from one device to another, but there’s no reason you can’t just stand nearby and listen to that same data as though you were the device it was intended for.”īusinesses have actually used this kind of data to build consumer profiles. “We know where the data is in the air,” McDonald explains. The artists built sniffers made from eight Raspberry Pis and wireless antennas, tuned to the different frequencies of open wireless channels. "It's sort of like looking over someone’s shoulder," says McDonald, "except you’re doing it without actually looking over their shoulder.” As festivalgoers walked past the installation, the artwork grabbed insecure data and display it on monitors, while a hidden speaker whispered the stream of data-what networks you've recently connected to and websites you've visited, for example-like a creepy, demon-voiced Big Brother. Recently at Moogfest, a music and technology festival in Durham, N.C., McDonald with the help of fellow artist Surya Mattucreated an installation called WiFi Whisperer that called attention to all that data your phone is giving away for free. “Sometimes it’s really insidious or unexpected.” “Our phones leak data in a bunch of different ways,” says artist Kyle McDonald. If you’re connected to a wireless network, odds are high that little bits of data are trickling out of your device like water from a leaky faucet.
