Disassembling Digital Identity-Related Privacy into a Set of Services: SoaML-Based Services Design

Privacy could play a key role for digital identity protection and security, which are becoming major needs for individuals, organizations and societies. Digital identity management functionalities are increasingly delivered as sets of services, rather than monolithic applications. So, an identity layer in which identity and privacy management are interoperable could be more realistic and an acceptable situation in the context of distributed environments. Such interoperability could be offered through the design of a set of loosely coupled, publicly hosted and available to on-demand calls services and the implementation on open standards basis. The aim of the article is to disassemble digital identity-related privacy requirements that are drawn from global, domestic and business-specific privacy policies into a set of eight ready-to-use, granular and loosely coupled services that could accommodate a service-oriented architecture (SOA). OMG SoaML service architecture, service contract architecture, message type, service contract choreography, composite application components, and provisioning diagrams are provided.
