I've seen some interesting posts here recently, but I have yet to
see the topic of padding data with garbage.  It seems to me that
if you had an algorithm that would not only encrypt the data, but would
also insert random data into the original data (without following
a regular pattern) that it would be almost impossible for someone
to tell what was real information and what was just junk.  Although
the size of the document would increase, the difficulty in decrypting
the message would also increase considerably.

The only problem I can see with this method is how do you insert data
in a non-regular pattern and still have the ability to remove it later.
Please comment on this type of procedure.  I'm sure people have thought
on these lines before and would be interested in seeing what they have
to say......
