<title>Data protection and security issues of PACS</title>

Abstract

It is observed that the dataprotection aspects of PACS have hardly been explored, while for Hospital Information Systems (HIS) considerable attention has been paid to these aspects. In the dataprotection domain around HIS we distinguish the aspects data integrity (safety), usage integrity (confidentiality, privacy) and availability. A wide range of measures (dealing with hardware, software or organization/procedures) has been suggested to achieve adequate protection. For each system a selection of the suggested measures has to be made, where risk is balanced against costs. It seems that it is taken for granted that the usual measures as implemented for HIS will also be adequate for PACS. In this paper dataprotection aspects for PACS are discussed. Apart from similarities with the HIS situation also differences will be identified. In particular safeguarding the image databank requires special measured. Dataprotection should not be an add-on of the system, it should be taken into account in the design phase. As an illustration two alternatives for the organization of the image databank will be considered from the point of view of dataprotection. The one being consecutive historical storage of images, the other the clustering of images of the same patient on the same volume in the storage system.
