And if you use OCR, you'll need gibberish text representing the
digital signature. Is that a reason to dump digital signatures, or
to relax the "perception of covert channel" constraint? The average
person won't care about covert channels unless DRE vendors bring it
out, and they are even more vulnerable to the same challenge. We
must publish the content of the bar code, if only to allow 3rd party
verifiers and tabulators.
