An innovative trust-based security model for Internet systems is proposed. The TCoRBAC model operates on user profiles built on the history of user with system interaction in conjunction with multi-dimensional context information. There is proposed a method of transforming the high number of possible context value variants into several user trust levels. The transformation implements Hierarchical Agglomerative Clustering strategy. Based on the user’s current trust level there are extra security mechanisms fired, or not. This approach allows you to reduce the negative effects on the system performance introduced by the security layer without any noticeable decrease in the system security level. There are also some results of such an analysis made on the Gdańsk University of Technology central system discussed.
