Generic and Complete Three-Level Identity Management Model

Identity management has become an issue of central importance. It is relevant to service composition and provisioning in telecommunications and in computer systems, especially to their security, enrichment and customization. However, the plentitude of proprietary and open source identity management solutions causes interoperability problems as well as legal issues. This in turn slows down the pace of services development. The key step for reconciliation and cohesive creation of identity management systems is to create a single and complete identity management model. This paper is a step towards this approach. It proposes the generic and complete three-level identity management model.
