Abstract:
Health care is currently witnessing increased specialization as well as a need for integrated care delivery. As a
result, care organizations should collaborate and in order to facilitate this, e-health collaboration platforms are
being created. Access control is a primary concern for such cross-organizational platforms and efficient access
control management is crucial to their adoption. Federated access control is a potential technique to achieve
this and our experience in multiple research projects shows that federated authorization is an essential building
block for future collaboration platforms. However, this technology still faces open research challenges. This
paper wants to spark research on these challenges by motivating the need for federated authorization in the
context of a real-world collaborative care platform. Based on this case study, we also discuss the state of the
art and present a set of key requirements to realize wide-scale adoption of federated authorization in
practice.
