How can I be sure that my data will never leak anywhere?
The world is a dangerous place. You can
never be sure your data will never leak, just as you can never be sure that you will not be robbed or assaulted walking down the street. There are many things you can do to protect yourself, online or on the street, but there is no perfect security. And even if you implement the latest and greatest and best security measures... you can still be victimized. It doesn't need to be
YOU that compromises your data... you can be exposed by your bank, your health insurer, your government, the companies you interact with (for-profit or non-profit alike), even the web sites you visit (porn?).
Sorry, I appear to have woke up on the doom-and-gloom side of the bed this morning!


Good luck!
