1. 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.

Write a program that writes 55H to every byte of every unallocated sector?


2. 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.

To easy to corrupt and lose the thread


3. Still working on data that has to be kept indefinitely,
watch this space.
