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

       | 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?
