Aktivieren und Deaktivieren von Softwarefunktionen

摘要

This application relates to a method of enabling and disabling software features in a software-implemented feature set, to the software itself and to a device with the software thereon. In accordance with the method of the invention, a token formed from identification and feature related information is sent to an authorization device. The authorization device creates a key from this information and sends the key and information on the authorized feature set back to the device. The device generates its own version of the key and compares its version with the received version. If the two keys match, the authorized feature set is implemented.
