The sharing of medical data between different healthcare organizations in Europe must comply with the legislation of the Member State where the data were originally collected. These legal requirements may differ from one state to another. Privacy requirements such as patient consent may be subject to conflicting conditions between different national frameworks as well as between different legal and ethical frameworks within a single Member State. These circumstances have made the compliance management process in European healthgrids very challenging. In this paper, we present an approach to tackle these issues by relying on several technologies in the semantic Web stack. Our work suggests a direct mapping from high-level legislation on privacy and data protection to operational-level privacy-aware controls. Additionally, we suggest an architecture for the enforcement of these controls on access control models adopted in healthgrid security infrastructures.
This paper addresses the problem of dealing with privacy management of confidential data stored by enterprises and other organisations. We describe an innovative solution based on an adaptive privacy management system. In this system (arbitrarily complex) data structures are retrieved from standard data repositories, in such a way that parts of these data are obfuscated and associated with privacy policies. Data structures containing confidential data are "first class" objects that can be sent to other parties. Entities that try to access their content can be different from those entities that retrieve these objects. In particular, a Privacy Management Service decides what is visible at a given time for each specific request for content. The visibility of (and access to) the obfuscated data is adaptive, depending on the requestor, the context and purpose. Hence multiple "views" on a data structure can be provided by our system. Our research and development is work in progress; the aim of this paper is to share and describe our current results.
