Scientists at the Karlsruhe Institute of Technology in Germany have demonstrated that WiFi routers can be used to track individuals even without their phones present, raising privacy concerns.
The research, conducted by scientists at the Karlsruhe Institute of Technology in Germany, revealed the potential for WiFi signals to track people using sound waves. The experiment showed that it’s possible to monitor individuals even if they don’t have their mobile devices with them.
According to the New York Post, the scientists were able to track people using sound waves from WiFi routers that surround people every day. The details of how this tracking is achieved weren’t fully elaborated in the provided summary, but the implication is that the routers emit or reflect signals that can be analyzed to determine a person’s location or movement.
The study highlights a previously unknown vulnerability in everyday technology and suggests that individuals may be subject to surveillance without their knowledge or consent. The New York Post article frames this as a potential privacy issue, as it demonstrates that constant connectivity, even without active device use, could be monitored. The researchers have not yet released details on potential countermeasures or the extent to which this technology could be deployed.
