This, like PRISM, is governments having to adjust to the loss of privacy as well. The 16 year old girl whom Wal-Mart knows is pregnant because of her loyalty card purchases thought she could keep it "secret". But secret is not what you don't tell people, it's what you don't reveal.

Governments the world over are finding out that their secret airbases, their secret flights, their buildings and purchases are just "private".

You really have to work at keeping secrets. So instead of pretending you can keep everything secret, try being open by default. You will find it a lot easier to concentrate on the things you want to keep secret then. Oh - and never ever let your secret near anything digital
