</div>The trick is to make the cover traffic actually useful for<br>
end-users.. ideally by making *all* of their everyday<br>
operations a part of the cover traffic. That also implies<br>
that it makes sense to aim for one and only one anonymizing<br>
protocol stack that should integrate all future and past<br>
internet applications, and to make properties like latency<br>
and depth of anonymization configurable by the applications,<br>
so that the routing layer can treat a secret conversation<br>
differently from a bulk video stream. Still, the video<br>
stream you watch while you chat can be enough to protect<br>
your metadata better. GNUnet provides file sharing for<br>
that purpose. secushare is working to add multicast pubsubs<br>
and social networking, so you can indeed be watching a<br>
stream or have chitchat about the weather be going on in<br>
the background that produces cover for the actual private<br>
stuff.</blockquote></div></div><div dir="auto"><br></div><div dir="auto">This could be easily be achieved with something like having a custom smart security camera and a NAS locally plus one remote, that all coordinates with your other hardware to adjust their bitrate in/out, such that your total bitrate over the anonymizing network is close to constant. </div><div dir="auto"><br></div><div dir="auto">It would be pretty simple - it's more effective with friends, so you and your friends all have your security cameras record, you all upload, you all keep copies of some of the other's streams, and the NAS:es can also be used for regular backup purposes (but security cameras as a 24/7 application is both meaningful and flexible). </div><div dir="auto"><br></div><div dir="auto">Whenever you upload more, your camera adjust to upload less.
