Therefore it is obvious to define one Fig. 3. ) . 20 E. Hermann history, the Dataset History. )). The Dataset History contains the complete information about the sources and actuality of the data contained by the dataset of the agent. Definition 5 (Dataset History of an agent) For each instant of time t ∈ N and each agent x ∈ SA let x AH t with the property ∀ j ∈ Ot : ∀ t1 , t2 ∈ N : (j, t1 ) ∈ x AH t ∧ (j, t2 ) ∈ x AH t =⇒ t1 = t2 be the Dataset History of the agent x. The Dataset History is the set of tuples (j, t ) of the object or agent j that have been read accessed by the agent x in the past, or where the dataset has been read and has been written to x afterwards and the instant of time t of the individual read access to j.

Hardware UCON Engine (HUE) [25] is another enforcement mechanism based on trusted computing that unlike most mechanisms does not rely on a built-in Trusted Platform Module (TPM). Instead, HUE is designed as a secure co-processor with a designated software stack to provide integration with the operating system. While obviously more flexible and efficient than TPM-based systems, the downside is that it the tailor-made hardware is not commercially available. Software-based enforcement. The RightsEnforcer [24] is a product for enforcing simple usage control restrictions such as limiting the ability to view, print, copy and store.

6 Conclusion The main contribution of this paper is a preliminary evaluation of several approaches to access control for public screens used in a perioperative setting. The evaluation criteria used are derived from a risk analysis of the COSTT system. In the evaluation, the facilitator based and the situation aware approaches received high scores, and so did the possible extension of using pop-up windows or handheld devices to get access to additional information. Of the simpler and most feasible approaches, the location-based approach turned out to be the best candidate.
