Rule: Once an untrusted person has access to your fdb file, you have
no security.

If that is TRULY your requirement, then I am afraid there is nothing
you can do, regardless of database engine or encryption. The best you
could do is hide it through obscurity. I would suggest you don't
distribute the database, but rather host it on a centralised server
which your browser can then connect to on-demand.
