1. A method for safeguarding an apparatus in a medical environment against an unauthorised operation of the apparatus, wherein the apparatus is connected to other apparatuses via a network, and wherein authorisation is dependent upon a linking event between at least two linking partners within the framework of an operation of the apparatus, wherein one of the linking partners is an item of use which is used during the operation of the apparatus, the method comprising:
reading-in a first identifier for identifying a first linking partner of the at least two linking partners in a unique manner and a second identifier for identifying a second linking partner of the at least two linking partners in a unique manner;
applying at least a first calculation rule to the read-in first identifier and applying a second calculation rule to the second identifier for calculating a documentation value that defines a unique signature of each instance of a linking event between the first and second linking partners, wherein calculating the documentation value includes calculating a third identifier as a repetition value which uniquely represents a number of repetitions for a linking event between the first and second linking partners so repetitions of linking events can be documented in a distinguishable manner using a unique signature of the linking partners involved in the linking events;
causing synchronised storage of the calculated documentation value in memories of apparatuses of the network; and
safeguarding the operation of the apparatus for the first and second linking partners.
