Comment Re:Document escrow is not new. (Score 1) 208
How about you just give the document escrow folks a one time use pad cypher and simply keep your "secure" documents encrypted using that pad. You can then "update" everybody electronically with an encrypted document that they cannot decrypt until they can obtain the one time pad from escrow.
While you are alive, you need to protect your copy of the pad, but its not hard to invent some classy way to do that given that the pad has absolutely no useful information in it...Like using a your favorite MP3 or something...
I think that using the one-time-pad to encrypt multiple items ends up leaking information if someone gets their hands on those multiple updates. Since you are sending out those updates to "everyone", that doesn't sound optimal. I don't know that this "attack" is particularly feasible however.
