Approach of Protecting IHE-XDS-I oriented Medical Image Information

IHE-XDS-I (Integrating the Health-care Enterprise-Cross Enterprise Document Sharing for Images) is an inter-organization, involving multiple users, information sharing for medical image integration specifications. The medical image information that shared between the medical institutions mainly include medical images and the medical reports. This information is an important part of the patients medical records and plays an important role in clinical diagnosis, research and teaching. In this case, how to ensure the safety of this data is the key problem to be solved. This article proposes a scheme of IHE-XDS-I medical image information security protection and design an access control algorithm -- Based on cryptographic properties of multi access control algorithm to allocate minimum privileges to users of different institutions IHE-XDS-I, medical image information can be safe and flexible to be shared.
