- How about encrypting such news with an RSA-Key or so, and just forget
- the secret key. If anybody cares about the information, he can gather
- computing powers to factorize the public key, and then can read the public
- encrypted message. Just hope that computers are not fast enough into
- break the key in already 10 years :-) (Yes , I know, this is a silly idea:-))
-
- Just for my curiosity: How would you assure the information was stored in
- an archive,which will be openend in 30 years ? In every good thriller about
- spies, there are files which are not recorded anywhere .... :-)
-
- Second Idea: Assuming the information is reliably put into a kind of
- achive and the problem lies only there to get people to 'open' the
- archive after 30 years, make this independent from people.
- Any kind of physical process wil do: Place a radio-mirror in about
- 15 Lightyears distance (yes - silly - I know) and just send out the message
- you want to have publicly available after 30 Years. Or bury it somewhere
- where erosion will let it get to daylight after 30 years. Put the information
- in space, and give it a kind of orbit, which with high probability comes back
- to you after 30 years. In the meantime distance shall be as big as possible :-=)

- Dont take me too serious ;^)
