  There is one area that the IEEE is not working on, at least not directly: privacy and security.. IEEE fellow and member of the Wi-Fi sensing task group.. the goal is to focus on “at least get the sensing measurements done.” He says that the committee did discuss privacy and security: “Some individuals have raised concerns, including myself.” But they decided that while those concerns do need to be addressed, they are not within the committee’s mandate.

> it has been shown that SENS-based classifiers can infer privacy-critical information such as keyboard typing, gesture recognition and activity tracking ... since Wi-Fi signals can penetrate hard objects and can be used without the presence of light, end-users may not even realize they are being tracked ... individuals should be provided the opportunity to opt out of SENS services – in other words, to avoid being monitored and tracked by the Wi-Fi devices around them. This would require the widespread introduction of reliable SENS algorithm for human or animal identification.

Would this require a worldwide database of biometric signatures for each human that opts out?

    Of course, which is why we shouldn't have ever accepted any industry having the option to implement opt-out regimes.

    Of course advertising kinda screwed us in that regard.

Release papers to show Chinese we also have this idiotic technology...then crucially...don't use it on our own populations?

    Makes police raids for wrongthink much easier if the dissident used a public wifi.

      Passive WiFi radar does not require the subject to connect to WiFi.

      WiFi passes through many walls, floors and ceilings and those reflections can be used for human identification.
