in 2005 i developed 'Crypt DNS' software to encrypt dns queries. It's possible somebody else did it before, i don't know? I honestly wasn't concerned. A few years later somebody came up with "DNS Crypt" which was pretty much the same deal. At the time i was like, OK you flipped it around. lol. The company OpenDNS was promoting it. They still do.
Not sure if it's that exciting, a VPN or proxy is better.
When I was developing crypt dns I noticed that the 'google page rank' plugin (i don't think chrome was out in 2005? but maybe? google search says 2008.) totally ignored the system configuration and did all DNS queries using google's DNS servers. I reported it as a bug, not sure if they "fixed" it. (of course not, it was not a bug right?).
So here we are in 2018 and google has invented encrypted dns queries. it's fine, have fun, but no patents on it right?
There was a recent article about a solo engineer wrecking some autonomous car patent, because it was a bogus claim. (i think that's what it was?)
