Abstract

The purpose of this work is to give a service provider or a resource holder the opportunity to evaluate the trustworthiness of each potential client, react to the client's activity by adapting access policies to the actual risk level, and derive user's access rights from his previous behavior, recommendations from third party and the actual circumstances. It is supposed that the system is able to observe and to log the activity of each client and use this information to estimate correspondent trust values.
