If you don't want your scheme broken quickly, use widely respected

not to give away the solution as part of the code you supply to
customers.
With the integrity of your keys in tact, you can then blacklist
any keys you discover being published on sites like MacSerialJunkie.com
In a well-known (now dead) music player app, you could see the
blacklisted keys when opening the executable in a hex editor as plain
text. Copy it over, change a digit, save, and boom - you got a great
working serial.
