Make a distributed system. Require the user to connect

some service.
Only deliver results.
Yes that would be a very effective solution. If the
input
data is provided to this service, and the output data
is
encrypted, and only the dongle knows how to decrypt
this
data, and each piece of data is only decrypted within
the
dongle, then copy protection may be close to
uncrackable.
You don't need a dongle then.
I would need the dongle to hide the decryption process. I
am
aiming to be as uncrackable as possible.

You don't need an decryption process, only authentication.

From a copy protection point of view you may be correct.
From an intellectual property protection point of view there
would still be a gap in protection if the data was not
encrypted and decrypted within black boxes.
