Elmar...

My current concept for making a Firebird Embedded Edition somewhat secure 
without a password (and as you say, using password means little if people 
already know a database;s internal structure) is to offer two levels of 
encryption.  The first would be using DotNetZip to compress and encrypt the 
Firebird database file into a zip file with a pass word.  The next level of 
encryption would be to take the zip file and encrypt it again using standard 
file encryption technologies (ie: AES)  Each set of compression\encryption 
processes would use a different internally generated key every time the process 
is initiated.

This may not be a perfect solution but I have it working to a point where the 
response time of these processes are acceptable on a Firebird database file of 
1.5 gigs.  However, it will be up to the user to set what they want through my 
application's security options, which will provide the option to do one or both 
security processes upon opening and closing the application or upon demand.

My concept is distantly related to your own Encryption schemes in Firebird 3.0 
where your security is supported by third-party plugins instead of using a 
singular security scheme built in to the database engine.

I'm not familiar which the technique SQLite uses.

But either they are using the password to encrypt database or it is an
fake protection and anyone can use an modified SQLite to access that
database which is simply ignoring password.

Even the "server side security" is meaningless once the illegitimate
user does have direct access to database file.

Your idea sounds like the "security by obscurity" approach used in some
closed-source systems as e.g. MS-Access - ask google how to remove that
password protection. That approach is worth nothing in an open source
context.
