hi!

at first i want to describe the situation i am: customers get a cd,
with an application and a firebird database. the customer has to
install the whole database server to get access the database. the
isc4.gdb has only one user which only my application knows (i don't
want other applications to read my database!).

now i got one big problem: what if the customer changes the isc4.gdb
to the original one? each application (ibconsole,...) would have
access to my database and all its content.

is there a way to avoid this problem?

thanks for you help!
