That depends on your delivery mechanism.

You can render text in PDF or HTML in black-on-black, and it will *look*
right, but the text will still be there for people to copy and paste,
search for, etc.  If you are delivering dead trees printed with the PDF,
then the information should be relatively safe.  This would be
relatively easy to implement; a small change to the CSS for HTML, and a
fairly straightforward implementation of the redact attribute in the FO
stylesheets.

You could also try printing a series of non-breaking spaces or Xs in
black-on-black, equal in length to the characters in the elements in
question; the stylesheet customization would be a bit more complicated
for that solution.

(La plus ça change... I remember a certain government agency asking for
this feature in DynaText in 1995 or so...)
