There are several things you could try, but you can't really guard against
this for experienced users who know how to work with IB/FB directly. You
could try adding a special table with an encrypted key in a field and test
for this. Almost anything you do can be duplicated, though, by just backing
up and restoring the database to a different name, then modifying it.
