Method for protecting a device against operation with unallowed consumables and arrangement for the implementation of the method |
摘要 |
In a method and apparatus for protecting a device against operation with unallowed consumables whose authenticity is checked in a remote data center, at least one code word is generated, an allocation to a specific consumable is stored in the form of a dataset with a reference code word, the consumable is aggregated with the generated code word, which has a predetermined relationship to the reference code word or to a group of reference code words that are stored in the data center. An operation for the replacement of a consumable in a device remote from the data center is detected and a communication connection is set up between the device and the remote data center and the code word aggregated with the consumable is communicated to the data center. The communicated code word is received in the data center and the authenticity of the consumable on the basis of a stored reference code word is checked at the data center, which transmits a message to the device after checking the code.
