The copy protection system is a combination of a signature method and a coding or encryption method that uses a variable key. The data set is written only onto a predetermined device and it is released to a host for reading and deciphering only upon proper authorization. Copying of the encrypted data set is entirely useless, because the dataset is signed with a unique identification (e.g. the serial number) of the device.
