Method for the copy-protected storage of information on a data carrier

A method for storing digital data information on a data carrier and for reading the information therefrom uses a disk having an individual digital identifier. A signature is formed, and the information includes information items, which can be processed by a first electronic data processing device only if the identifier and the signature are in a predefined relation to one another. To supply a household appliance operated by an electric motor with process control data, while ensuring that only original data are used, the information components can be processed by a second electronic data processing device even if the signature and the identifier are not in the predefined relation to one another. Also, a household appliance operable by an electric motor, in particular a food processor, has an electronic data processing device. A system and an integrated semiconductor circuit also realize the features for storing digital data information.
