You might be able to do something like that by opening all your IO handles via a specially made layer, and by tainting all sensitive data. Your layer can then prevent output of tainted data, unless it's the handle is marked to accept tainted data.

You might be able to do something by tieing your filehandles. Or you could dive in the Perl internals, and use XS to set some special magic on sensitive data.
