Abstract:

Information systems that use the mediation architecture are well suited to accessing heterogeneous data in a distributed environment. These mediation systems utilize a central security mediator that is primarily concerned with securing the internal structure of the mediation system. The current problem with this approach is that clients are unable to have authority and administer the security of their data during the collaboration with the mediation system. This creates a black box scenario from the perspective of the client towards the mediation system, which can have great consequences in transactions that deal with sensitive data within an untrusted environment. In this paper, we present a solution in the form of a decentralized mediator that provides all parties involved in a transaction within the mediation system autonomy over their security that is security model independent and dynamic at runtime. Our approach allows the client to manage the access to data during a transaction with the mediation system.
