Paper Abstract

The power of Grid and Cloud computing enables the development of new telemedical services that can be offered using high-speed networks, which are increasingly available to hospitals in Germany. Currently the implementation of such new services is often prevented by hurdles such as heterogeneous IT infrastructure, data protection and safety considerations, and by the significant requirements in terms of transfer speed and computing power. The MedInfoGRID project, which is funded by the German Federal Ministry of Education and Research, is developing a virtual “documentation and information center” for the management of integrated distributed databases. This portal will enable researchers to gain access to relevant imaging, findings and therapies. Because of the large volumes of image data, the image distribution approach implemented in the project, based on DICOM, requires careful attention. For example, some of the post-processing algorithms used require a conversion of non-DICOM image sources including color-encoded pathology images to DICOM and their integration with other images sources. Also, data protection and more generally IT security are a highly relevant topic for the project. Different DICOM conformant data security concepts have been analyzed. First results include a concept for a DICOM conformant selective encryption of personal data (patient demographics etc.) that only requires the encryption of about 5% of the data to be transmitted, thus significantly reducing the speed penalty caused by encryption and decryption. The concept enables standard DICOM tools to correctly process the secure images if the processing algorithm does not depend on the personal data.
