The fractal steganography sounds promising. Is this yours or
has it been done?
The need for authentic sigs on architectural and engineering
drawings is not merely aesthetic. Right now municipal agencies
will not accept digital documents because of the lack of
verifiable authorship to establish responsibility, and
liability, for the health and safety of the design and
construction. Hard copy with original seal is required to
prevent unauthorized manipulation.
Beyond copyright protection, architectural and engineering
documents are means to guide actual construction, rather than
end products like paintings and drawings in the art world.
If there could be a way for buildings themselves to convey
authenticity, say, that they are healthy and safe, by a kind
decryption by the public that could help prevent concealment of
shoddy construction. It's not the drawings that assure safety
but field verification of the end result that construction work
was done right.
What a great help if a building could convey its own message of
authenticity about its fitness and safety for habitation and
use. That might keep us architects more honest.
Probably a long shot that your fractal idea could be stretched
this far, but it is certainly needed in the flim flam world of
New York City real estate where deception about building safety
and health is all too common.
Any other thoughts?
