Platform for Inter-Institutions E-Governance Based on a Dynamic Web Services Composition

Digital identity can be defined as the digital representation of information about a citizen, entity or organization. institution may need data from other institutions to enable construction of a full or partial digital identity in order to offer its services However, even if, those data are available in each institution, they are not exploitable by the other institutions. Furthermore, no systematic collaboration can be handled to grant access to such data in the absence of a platform offering services for this purpose. The authors propose an interinstitution' web services-based platform, allowing an institution to import data from other institutions in order to construct the needed digital identity for offering its services. The platform relies on an algorithm to perform a dynamic composition of the offered web services.
