| dc.description.abstract | Inter-organisational data-exchange is common in inter-organisational value-chains. Currently information providing organizations enrol users of suppliers, in order to enable them to access their services and information. This leaves some users with the issue of handling multiple credentials, introducing risks of password-reuse [Iv04] and weak-passwords [Ne94]. Federated identity management eases this scenario, by enabling users to authenticate against their organizations' identity provider [Hü10]. However, the costs involved in managing the underlying identity and rights lifecycle have hardly been considered. This paper addresses this gap, by using the principal-agent theory, and transaction cost theory, structuring the identity lifecycle using [BS08] [IS05] [IS10], and estimating the management costs. We finally analyse the economic benefits of federated identity management in inter-organisational information exchange. We find that while process costs for executing the identity lifecycle are reduced for the information provider, by introducing federated identity management, the control costs reduce, and in one case even diminish this cost benefit. We briefly discuss our findings, and conclude that further mechanisms and research is required to reduce the efforts in auditing, in order to fully unlock the security and economic benefits of federated identity management. | en |
