[1] Step 6 will probably never happen if you show a border guard or customs official an article about encryption. You will not get safely through customs, you’ll end up on a secret list and get hassled every single time you travel for the rest of your life. As the database you’re in ages (and people begin to forget how it was created), you might be simply barred entry into places you want to go.
