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.
