I remember having seen something called ADM that was a really efficient
protection system.
It was released by American Mitac, I couldn't figure out how exactly.

How it worked : It replaced your boot sector with one of its own. The
program would ask you to enter a username and password before starting
the system. A maintenance program allowed you to give a user a selective
access to the disk's partitions (so that user 1 could only access partition
1 and 2 for example), and to give none, read or read/write access.

I think it crypted the partition table to handle this. Never noticed any problem
with it though.
