Security issues for data sharing and service interoperability in eHealth systems: the Nu.Sa. test bed
This addresses security and interoperability issues for eHealth systems in Italy, but it is incremental as it builds on existing standards and tools.
The paper tackles the problem of secure data sharing and service interoperability in eHealth systems by presenting and implementing a framework focused on privacy, authorization, and encryption, with results showing good feasibility and scalability in thousands of test cases over more than a year.
The aim of the Nu.Sa. project is the definition of national level data standards to collect data coming from General Practitioners' Electronic Health Records and to allow secure data sharing between them. This paper introduces the Nu.Sa. framework and is mainly focused on security issues. A solution for secure data sharing and service interoperability is presented and implemented in the actual system used around Italy. The solution is strongly focused on privacy and correct data sharing with a complete set of tools devoted to authorization, encryption and decryption in a data sharing environment and a distributed architecture. The implemented system with more than one year of experiences in thousands of test cases shows a good feasibility of the approach and a future scalability in a cloud based architecture.
