Abstract (EN):
Access control is a crucial part of a system's security, restricting what actions users can perform on resources. Therefore, access control is a core component when dealing with eHealth data and resources, discriminating which is available for a certain party. We consider that current systems that attempt to assure the share of policies between facilities are prone to system's and network's faults and do not assure the integrity of policies life-cycle. By approaching this problem with a blockchain where the operations are stored as transactions, we can ensure that the different facilities have knowledge about all the parts that can act over the eHealth resources while maintaining integrity, auditability, and authenticity.
