Do you have a: 1) List of files on a computer you know who they are (say you generated their hash when you knew they're OK), and you wish to make sure no other file will sneak? The basic problem here is, finding a computer you can trust in a hostile environment. Once you have a computer you completely trust - copying only those files in the list is trivial. 2) An oracle (usually the information security officer) who can, given a file, verify it is not secret. In that case the basic problem is given a non-secret file, verify that no other information is included with it via stenography. Or is it some other scenario that I'm missing?
