I've been keeping a journal for many years, in electronic form. In it I discuss very personal matters about me, my family, my friends, my children, etc. I try to be as honest as possible.

Nobody but me has ever read it, or even knows it exists. I would like to keep it that way.

However, it might have some value for researchers in the future (or it may of course not, and this may just be my ego speaking).

Anyway, how would one proceed to "send" this into the future (after my death) so that

- it has zero chance of being found by the people who knew me, including my children and their children

- it has a fairly good chance of being found, still in usable form, after that (say, in 100 years)?

It should probably be printed on paper, but where to put those?
