Intermediary Technical Interoperability Component TIC Connecting Heterogeneous Federation Systems

The spread of digital identity raises many new opportunities and challenges concerning identity. A set of identity management systems has been developed to handle such identities. The aim is both to enhance the end-user experience and to provide secure access for users. Nowadays, we have a large number of heterogeneous identity management initiatives. Proof of its eligibility for identity management is provided under the federation system. The strength of security domains within federated systems is a trusted agreement between communicating entities. However, Federated systems are challenged by the interoperability issue across those federated heterogeneous systems. This work aims to provide a technical interoperability approach for the different federations. The researchers are offering a technical interoperability component TIC, as a midway tool that will enable identity data to be interchanged between heterogeneous federations in total transparency. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.
