That’s the promise (and the privacy dilemma) of WhoFi, a new system mapping your unique signal signature. Could this tech be the next leap in security, or is it a surveillance risk hiding in plain sight? Would you trade privacy for convenience if your home could ID you by Wi-Fi alone? #Tech #WiFiSecurity #BiometricTech
