All of this - and more - would combine with information gleaned from a variety of sources: a GPS transmitter to keep tabs on where that person went, audio-visual sensors to capture what he or she sees or says, and biomedical monitors to keep track of the individual's health.' And so all privacy ends (from Wired).
