Well, I would take with me a notepad with a written story by me containing the 12 words of the seed distributed along the whole text, very well disguised in a way nobody could suspect anything. You just need to be creative to create a coherent tale, what shouldn't be so hard, since seeds' words are really common ones, being possible to add them to any fictions easily.
And I doubt someone would steal a cheap notepad from your luggage or seize it, because there isn't any reasonable cause to justify that at first point.
This is quite an easy and possible solution. No one will seize or take away the notepad, but we don't know what is our fate. As a common man we can easily move to different countries carrying the notepad. By some problem while we're travelling someone stole the luggage carrying the notepad, what to do. To avoid such scenario memorizing it is good choice or should have the same stored in some other tale.
Recently saw a post in which it is mentioned about Danish police having the right to seize belongings of people entering the country as refugee. By situation if we turn to be a refugee and was to enter Denmark what to do?
