Situation-aware trust management

ABSTRACT

We present a knowledge-intensive and model-based case-based reasoning framework that supports the truster for situation-aware trust management. The suggested method augments the typically sparse trust information by inferring the missing information from other situational conditions, and can better support situation-aware trust management. Our framework can be coupled with existing trust management models to make them situation-aware. It uses the underlying model of trust management to transfer trust information between situations. We validate the proposed framework for Subjective Logic trust management model and evaluate it by conducting experiments on a large real dataset.
