The OCR idea is indeed nice. However, it is only good for small
amounts of data, or where the accuracy is not so important (English
texts). It is not so good for Hebrew or data (numbers), not to mention
binary data.
Your suggestions assumed there was someone (human) able to go over the
data and say "yes, this is what it is supposed to be". If this is large
amounts of binary data, how do you plan to do that? You will need some
computer that can be trusted. If you do have that, things are, already,
much simpler.

It's more of a logical issue than anything else.
If the "secret" data is not easily recognizable, then the
whole system is at fault.
Close the doors and check every bit. There's no other way.
OR
Follow the output, check who'll access it, where and how,
in short, create a honeypot.
