In a high-tech world like we live in, there are many ways spies and snoops can keep a bead on you. Is you life interesting enough to elicit such dubious actions as spying and snooping? For the high-tech snoop, almost any tool can be used for their deeds. What if we told you that WiFi signals can help spies and snoops?

Neal Patwari of the University of Utah has discovered that any movement someone makes affects the strength of a WiFi signal. He also realized that this could be accomplished through walls and other barriers. This means that a snoop could possibly set up a WiFi network from outside your house, track the signal strength inside your house, and use that to track movement.

Does knowing this make you want to build super-secure walls in your house made to block WiFi? Don’t worry, these folks will find another way for sure.
