I'm not sure what "cognometrics" means -- Is the author suggesting that
one should hash a FILE, such as a passport photo, when selecting an
encryption key? This would have the advantage of precluding a user's
effective knowledge of technical details of the actual key. If the initial
file were selected from an album (on a CD, e.g.), then sequential photos
from the same gallery, or sequential tracks from the same audio CD, etc.,
could key successive blocks of the plaintext. Exchanging passwords might
be as simple as mailing a fair copy of a CD, or discussing a particular
track from a popular music album.
