Towards User-centric Identity Interoperability for Digital Ecosystems
نویسندگان
چکیده
Digital Ecosystem is a new paradigm for dynamic IT business integration. Its main focus is to provide microand small enterprises with technological solutions bootstrapping their growth and cooperation. In a Digital Ecosystem, institutions compete in some business aspects and collaborate in others, and thus form stable and unstable coalitions. Such a dynamic environment becomes a bottleneck for identity management solutions. Existing and well-researched solutions for identity federation are either too restricting and not flexible enough to support the dynamic nature of ecosystems or they are too complex and difficult to adopt by small enterprises. In this paper we present a model targeting cross-domain identity interoperability between distributed ecosystem entities. The model is based on the recent OASIS SAML v2.0 standard to provide interoperability and convergence between existing identity technologies. The paper presents the basic and extended identity models for single services and service compositions. The aim of this research is to allow small and medium companies to use and enhance their current identity technology with a practical and easy to adopt identity management solution that scales up to the dynamic and distributed nature of digital ecosystems.
