The trick is to make the cover traffic actually useful for
end-users.. ideally by making *all* of their everyday
operations a part of the cover traffic. That also implies
that it makes sense to aim for one and only one anonymizing
protocol stack that should integrate all future and past
internet applications, and to make properties like latency
and depth of anonymization configurable by the applications,
so that the routing layer can treat a secret conversation
differently from a bulk video stream. Still, the video
stream you watch while you chat can be enough to protect
your metadata better. GNUnet provides file sharing for
that purpose. secushare is working to add multicast pubsubs
and social networking, so you can indeed be watching a
stream or have chitchat about the weather be going on in
the background that produces cover for the actual private
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.
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).
Whenever you upload more, your camera adjust to upload less. Whenever you
download more, the streams sent to you have their bandwidth adjusted down
accordingly too. Coordination can help everybody maintain near constant
traffic, by changing bandwidth and routing as needed. People who don't need
constant cover traffic can handle any unbalanced traffic demands for the
So there's a clearly useful source of constant traffic, and a way of
maintaining it constant.
