I seems unrealistic. Just run a Tor exit node and encourage a lot of other people to do the same, similar benefits and no downsides.
A more realistic and useful one would be for email clients sending mime email (almost all of them) to always send an encrypted version as well no matter the options in the client. No keys set up? Then just send random data that looks right.
Email providers might hate this because of the bandwidth but if you start sending a lot of encrypted data around right now you are going to match a profile you probably don't want to match. I think step one is to make sending encrypted text around a normal thing.
I want to say a sentence to someone, but in order for an unintended listener not to understand what I'm saying I will say 10 sentences. Five of which will be "I will kill you and everyone you know" and "I will bomb America".
Isn't that just a meaningless waste of energy?
-- The government spies on you because you make it easy for it to do it. Instead, keep your personal data personal, use encryption and there's not much more that it can do, without becoming physical... ( it has no problem doing that either, but at least its intentions will be more obvious that way, and hopefully will wake up all the ignorants that think that some old guys peeking into everyone's lives is justified).
It is. People suck at being random, so there's a good chance that those "false positives" will actually be trivially filtered out. And even if not immediately, this is an algorithmic problem - they will just throw few dozen kUSD at some math and CS graduates to make it go away.
I agree with you and TemPorAL (apologies for incorrect capitalisation!) that these are probably a waste of time for the user - they don't work.
NSA and GCHQ are very good at math - I'm constantly surprised that people don't appear to get this. Maybe it's because secret government agencies don't publish much?
Just for fun here's one extension: (http://trackmenot.org/) (https://cs.nyu.edu/trackmenot/)
People can probably come up with ways to improve it. But still, these are probably pointless measures.
Instead of hiding all our private communication we can generate fake communication across the whole internet which might raise flags in NSA's system. (I would have given more concrete examples but I am scared that tomorrow some NSA freak might knock on my door.)
