New WIFI Systems Will Take The Police State To A New Level Tracking Your Every Move

Now there might be a new concern on the horizon – public WiFi signals that can identify and track groups of individuals, even if they are not holding a personal connected device.

 

As we have come to learn, one of the hallmarks of technology is dual- or multi-use capability. It is for this reason that we are softened up with all of the benefits, before being introduced to the darker side.

 

Researchers continue to pursue invisible, pervasive ways to track human beings. Below is a chronicle of how WiFi signals are being used in creative new ways to ensure that whether or not you have opted out of the latest gadgetry, you still will be caught in an ever-widening net of the latest surveillance tech.

 

A little more than two years ago, the first enhancement of Wi-Fi was labeled WiTrack. It marked an improvement over a discovery by MIT researchers a few months previous that they had called Wi-Vi. At the time, researchers were able to use dual signals to detect the general location of moving objects behind walls, but not an exact image.

 

WiTrack uses radio signals to pinpoint a person’s location more accurately. An MIT press release explained the significant difference between Wi-Vi and WiTrack: WiTrack operates by tracking specialized radio signals reflected off a person’s body to pinpoint location and movement. The system uses multiple antennas: one for transmitting signals and three for receiving. The system then builds a geometric model of the user’s location by transmitting signals between the antennas and using the reflections off a person’s body to estimate the distance between the antennas and the user.
