1. A method for inserting a further data block into a first ledger, the first ledger including a plurality of data blocks, the method comprising:
receiving a medical dataset via an interface, the medical dataset being a log of an access of an entity to a medical apparatus and the medical dataset including an identifier of the medical apparatus and an identifier of the entity accessing the medical apparatus, the access of the entity to the medical apparatus including an interaction of the entity with the medical apparatus;
selecting a parent data block of the first ledger, the parent data block being selected based on a maximal sum of distances from the parent data block to each of a first origin data block and a second origin data block of the first ledger;
determining the further data block via a processor, the further data block including the medical dataset and link information, and the link information including a hash of the parent data block of the first ledger;
inserting the further data block into the first ledger via the processor; and
granting remote access of the medical apparatus to the entity via the processor after the inserting the further data block into the first ledger, the interaction of the entity with the medical apparatus being a remote connection between the entity and the medical apparatus.
