The European project p-medicine creates an information technology infrastructure that facilitates the development from current medical practice to personalised medicine. The main access point to this infrastructure is the p-medicine portal that provides clinicians, patients, and researchers a platform to collaborate, share data and expertise, and use tools and services to improve personalised treatments of patients. In this document, we describe the community-based structure of the p-medicine portal and provide information about the p-medicine security framework implemented in the portal. Finally, we show the user interface and describe the p-medicine tools and services integrated in the portal. Copyright: © the authors.

Efficient collaboration and data sharing are essential prerequisites for improving efficiency, safety and outcomes in medicine. Current separation of clinical research and care creates a significant knowledge gap, especially in the case of complex diseases such as cancer, hampering research and slowing down the transfer of the latest research results to patient care. The momentum gained by initiatives focusing on these aspects indicates that under the right circumstances, the biomedical community is ready and willing to open up. However, main technological barriers concerning semantic interoperability, security and privacy need to be addressed to make this change possible. In this paper we describe our scalable, standards-based and open approach towards addressing these issues in the context of a large initiative with focus in oncology.

Secure access to patient data is becoming of increasing importance, as medical informatics grows in significance, to both assist with population health studies, and patient specific medicine in support of treatment. However, assembling the many different types of data emanating from the clinic is in itself a difficulty, and doing so across national borders compounds the problem. In this paper we present our solution: an easy to use distributed informatics platform embedding a state of the art data warehouse incorporating a secure pseudonymisation system protecting access to personal healthcare data. Using this system, a whole range of patient derived data, from genomics to imaging to clinical records, can be assembled and linked, and then connected with analytics tools that help us to understand the data. Research performed in this environment will have immediate clinical impact for personalised patient healthcare.

When building cross-organisation data sharing environments in the clinical domain, one is confronted with high security demands. Although at the present time, a broad range of security technology is available, typically not all desired functionality can be easily met. One of these requirements is managing access over dynamically instantiated contexts in collaborative environments. This requirement was encountered during the EU funded projects INTEGRATE and EURECA. This paper presents a solution which enriches XACML with context awareness without changing the policy language itself. Furthermore, it is shown that the presented mechanism (XACML request modification) can also be used for uniformly addressing other security challenges. © Springer-Verlag Berlin Heidelberg 2014.

Authorisation solutions that exist today offer a broad range of functionality for defining complex access control policies. A common requirement that is not covered by these solutions is dynamically instantiated contexts in collaborative environments. This requirement is one of the research topics of the EU funded INTEGRATE project. This paper will focus on the solution proposed for the INTEGRATE project which is XACML based. The approach taken to make XACML context aware, is to enrich the XACML specification using a contextual extension through a generic mechanism, without changing the XACML language itself. This contextual extension operates on the XACML requests with ultimate goal to simplify the management of context aware policies.
