A layered IT infrastructure for secure interoperability in personal data registry digital government services

摘要

In this paper we describe the architectural solution defined and implemented to ensure secure interoperability among information technology (IT) systems managing personal data registries in Italian municipalities and Ministry of Interior. The architecture features a clear separation between security services, provided at an infrastructure level, and application services, exposed on the Internet as Web services. This approach has allowed to easily design and implement secure interoperability, since - notwithstanding the huge variety of IT solutions deployed all over the Italian municipalities to manage personal data registries - existing application services have not required major changes to be able to interoperate.
