I've been giving some thought as to how to protect one's privacy from the ever growing snoopings of the Brit monarchy and all its lapdogs and subordinate dogs' dinners such as GCHQ, the MIxs and the po lice, and to kill off RIPA and the sending of innocent people to jail for not revealing their passwords and security keys to the plodderies.
- In case of computers being seized, you have to guard against previous data being scattered around the disk in various deletions. The solution here would be to store all data in an indexed data base file of such a size that it won't be moved willy nilly by the OS. Then, by overwriting records at fixed and known locations, previous data can be guaranteed to be deleted.
- When receiving encyphered messages, the one-time key is to be the previously received message, giving only one opportunity to read your message before it takes the place of the previously received message at the fixed location in the indexed data base.
- Still working on data that has to be kept indefinitely, watch this space.
