Privilege management infrastructure for virtual organizations in healthcare grids

This paper is focused in the management of virtual organizations (VO) inside healthcare environments where GRID technology is used as middleware for a healthcare services oriented architecture (HSOA). Some of the main tasks considered for the provision of a well established VO management are: management of users, assignation of roles to users, assignation of privileges to roles, definition of resources access policies. These tasks are extremely close to privilege management infrastructures (PMI), so we face VO management services as part of the PMI supporting access control to healthcare resources inside the HSOA.
