The scientists claim this identifier, a pattern derived from Wi-Fi Channel State Information, can re-identify a person in other locations most of the time when a Wi-Fi signal can be measured.

Are there any scientists out there working in stuff that's useful and beneficial to society? Or are they all just focusing on sneaky shit that makes it easier for The Man to make our life worse?
