@ ink that incorporates the owner's blood/DNA into it
I thought that was already done? I remember reading about a cartoonist who was using it to sign original of his artwork.
I don't suppose anyone thought of the practicalities of testing it (how long a a sequence would remain stable in the ink solvent and paper acid) but it was a cool publicity stunt.
