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. ## Claims ### Claim 1 A method for storing information comprising digital data on a data carrier and reading the information from the data carrier, the method comprising the steps of: a) providing a data carrier comprising an individual digital identifier; b) forming a signature comprising the individual digital identifier; c) providing information comprising a processing recipe and assigned machine control data; d) processing the machine control data with a first electronic data processing device and using the machine control data to control a machine only if the individual digital identifier and the signature are in a predefined relation to one another; and e) reading and reproducing the processing recipe with a second electronic data processing device comprising a human-machine interface, regardless of whether the signature and the individual digital identifier are in the predefined relation to one another; wherein the first electronic data processing device is part of a household appliance operable by an electric motor and/or the machine control data is a program sequence for a household appliance operable by electric motor. ### Claim 2 (depends on 1) The method according to claim 1, wherein the processing recipe is a food preparation recipe and/or wherein the machine control data comprises process parameters. ### Claim 3 (depends on 1) The method according to claim 1, wherein to create the signature an asymmetric key pair consisting of a private key and a public key is used, wherein the signature is generated using the private key, and a verification is carried out by the first electronic data processing device using the public key. ### Claim 4 (depends on 1) The method according to claim 1, wherein to generate the signature either the information supplemented by the individual digital identifier is encrypted with a private key or a hash-value formed therefrom is encrypted with the private key. ### Claim 5 (depends on 1) The method according to claim 1, wherein the signature is part of a file stored on the data carrier and comprising the information and the individual identifier, or is a separate file stored on the data carrier. ### Claim 6 (depends on 1) The method according to claim 1, wherein the information is stored on the data carrier as a “mark-up language” file. ### Claim 7 (depends on 1) The method according to claim 1, wherein the individual digital identifier is a unique serial number. ### Claim 8 (depends on 1) A system for carrying out a method in accordance with claim 1, the system comprising at least one non-transitory data carrier, on which information comprising digital data is stored, wherein the non-transitory data carrier comprises an individual digital identifier, wherein a signature comprising the individual digital identifier is stored on the non-transitory data carrier, wherein the information has at least first information components, which can be processed by a first electronic data processing device only if the individual digital identifier and the signature are in a predefined relation to one another, wherein the first data processing device is part of a household appliance operated by electric motor. ### Claim 9 (depends on 8) The system according to claim 8, wherein the information comprises at least one processing recipe and/or assigned machine control data. ### Claim 10 (depends on 8) The system according to claim 8, wherein the non-transitory data carrier is a USB stick. ### Claim 11 (depends on 1) The method according to claim 1, wherein the processing recipe is reproducible in textual and/or graphical form. ### Claim 12 An integrated semiconductor circuit with a control circuit for serial or parallel communication with a first electronic data processing device and a second electronic data processing device, the integrated semiconductor circuit comprising: a storage device; an individual digital identifier; information comprising digital data stored on the storage device, the information comprising a processing recipe and associated machine control data for a household appliance operable by an electric motor; and a signature comprising the individual digital identifier stored on the storage device, wherein the individual digital identifier and the signature are in a predefined relation to one another, the first electronic data processing device can only handle the machine control data stored on the storage device if the individual digital identifier and the signature are in the predefined relation to one another, and the second electronic data processing device reads and reproduces the processing recipe, regardless of whether the individual digital identifier and the signature are in the predefined relation to one another.
