This repeats a suggestion from 1994 about using computer assisted design programs to conceal text or other data: 1. CAD uses vectors to make graphics, including text, and most programs can import a wide variety of data from other formats. 2. Several features can manipulate CAD objects into unrecognizable forms by modifying scale, dimension, orientation, opacity and so on. 3. The scale feature is useful to reduce, say, a text of any length, or any digital object, to the size of a pixel. This pixel can be located, say, under a visible line, or, be made transparent as a "phantom" object. (An engineer "stipples" concrete with microdot exotica and lofts the docs to the Saudis, getting paid ten times the regular fee.) 4. Or, the text can be distorted by scale and dimension to appear to be a line serving another function. 5. It's a snap to encrypt the text and import it into CAD via several programs that do that duty. Then the message could be distorted or hidden as described above, for piggy-backing on an innocent- looking document issued, say, to GSA for replenishing the Blanco Bunker, where it would be opened by the cp insider-sou-chef for de-distorted, decrypted instructions on how to prepare and place the bean. 6. To be sure, the underlying CAD code of the ciphertext could be identified by an astute auto-message-vetter of the EOP and then the CADbreakers would be beckoned to the roachtrap. 7. Big shortcoming: how to securely transmit the location (virtual coordinates) of the hidden message and what modifications need to be reversed for message access. Beware of using 0,0,0 -- a near-universal data point for CAD docs. However, 0,0,2^50 miles might be overlooked if the 3d view is disabled. 8. Medium shortcoming: Full-featured CAD programs are expensive, however, the popular lite versions are cheap and can usually read the pricier output.
